Plastics Guy DuroBumps and a little more

[DuroBumps]

I think you all need to take a step back and understand what a bumpstops purpose is. It's primarily to limit where your max up travel point is and these obviously aren't doing that seeing as he started rubbing after installing them because they allowed too much compression and the bumpstop then failed. I'm fully aware that these aren't hydros but the failure happened at incredibly low speeds, less than 5mph. That's hardly into the hydro bump territory. The other side is completely intact even though it was ran much harder for several more days after the initial failure. Not trying to be a dick I just find it ironic how these bumps are marketed to be the toughest out there, designed for the hardcore wheeler, and when a single failure happens there's no backing behind them.

So if this happened at 5mph how did the suspension ever compress to the point of contacting the bump stop? Spring rate to low? No shock oil?? Must have been one hell of a boulder/cliff to compress the suspension to the point it even contacted the bump stop let alone compress it far enough to split.

Another issue is 5th gens do rub tire with 35's. You knew that ahead of time and that is why you suggested to your friend to use washers as shims to help prevent tire rub. Your boy threw you under the bus with that one.

And what the fuck do you mean by not backing of my product. I offered a full refund what else can I do?? Seriously???

I have several hundred of these identical bump stops on the market and I certainly cant justify making any changes to the design because of one issue. As you know yourself when there is an improvement to be made I make it!

Take a step back and realize that several Hundred of these 5th gen front bump stops have been sold without an issue and I find it Ironic that your friend told me on IG that the failure happen at high speeds and he was jumping his truck. He also mentioned destroying the tie rod end.
There is no need to bullshit me to try to prove your point.

All I can do is give a refund like I have stated, there is nothing else I can do.

Happens literally all the time crawling lol. Its called articulating. Come downhill and have one tire droop into a hole and the other get stuffed to maintain a level ride. That's how the suspension works. How could it be that I was not in my truck, it isn't moving but the tire is stuffed all the way up and resting on the bump stops. It's not a spring rate, valving, shock oil, whatever bullshit excuse. Its just articulation

I didn't suggest to him to run shims. I am the one that installed them. I sent you a PM to keep from "junking" up your thread but there was no response there so here I am. The bump stop should limit the up travel regardless of where it is positioned. 1/4" shim is not going to be the difference between failing and not here

And what the fuck do you mean by not backing of my product. I offered a full refund what else can I do?? Seriously???

Its one failed bump. He sent you a message and your immediate reaction was placing the blame entirely on him. Would it seriously be that hard to replace the 1 failed bump stop the could have failed entirely due to a contaminant in the mold or something of that nature? I don't think so. The refund is a step in the right direction but to me seems more of a way to brush it aside.

I have several hundred of these identical bump stops on the market and I certainly cant justify making any changes to the design because of one issue. As you know yourself when there is an improvement to be made I make it!

That's part of business, if a product goes out an runs fine but starts having issues a company makes the change. Is it more expensive? yeah that's what prototyping is for, to prevent that. Will you make the change? yes. But I distinctly remember the same situation with the 3rd gen bumps. I broke the prototype and was immediately told that it was my fault and can't expect them to do that. The change was then made and like magic they haven't broken.

Take a step back and realize that several Hundred of these 5th gen front bump stops have been sold without an issue and I find it Ironic that your friend told me on IG that the failure happen at high speeds and he was jumping his truck. He also mentioned destroying the tie rod end.

Im not going to sit here and be in a pissing match with you over the internet about this stupid bullshit and you being too stubborn to be open to suggestions or other possibilities of failure other than "it had to of been his fault". Its a waste of my time. Upon closer inspection I can see the hardware inside my front bump stops has started to tear a hole through the bump because it contacts under full compression pinching the rubber and tearing it. But clearly, that's my fault for using the included hardware that have been contacting the frame at full stuff since day 1 but as expected I was told that since I was the only one noticing the issue no change should be made to the proper hardware to give enough clearance.

No backing them. He is willing to return the purchase price. They are intended to replace stock bump stops. Do stock bump stops have two washers stacked behind them to limit up travel? Lots of variables here to deal with. What size tires are being run? How hard of an impact mangled the tie rod and could that have been a contributing factor?

Truck in question is running 2.5 radflo coilovers and 35s. The stock bumps had the two washers on them for 4 months before the durobumps went in. The tie rod wasnt magled from an impact, it bent in half climbing a ledge with the front locker on. Its a very common failure point on the newer trucks. Tie rod wouldn't have contributed to the failure at all, the failure happened very early on in the trail during the low speed crawling. I have the tie rod break on video. I'll see if the site will let me upload it

Swap in your stock bump stops and go take that jump again and let us know how it turns out.

@plasticguy this bromance isn't going to work out. Give the guy that busted the stops his money back because his low speed crawling requires hydro's.

 

[Theblackflag]

The truck wasnt jumped when the bumpstop failed. The passenger side failed early on in poison spider mesa. The driver side was fine and ran for several more days which included jumping it. It is still intact now. the passenger side is the only failure that happened

Apparently you don't understand that I am talking with the gentleman that owns the truck AND is the one who was driving it the day the bump stop failed. All I know is, the information you are providing as a third wheel is not the same information I received in messages on IG. If I really want to prove my point I can Copy/Paste those IG messages for everyone to read what I am trying to polity explain. Your story is BULLSHIT.

As I had asked before, "what else could I do?" other than offer the Full Refund and suggest the true solution to your buddies suspension issues. Which is GAS BUMP STOPS FOR JUMPING / HIGH SPEED DRIVING. Your friend clearly stated that he was hauling ass and jumping all day. Just like with your own Durobumps failure on your 3rd gen 4Runner when you were admittedly driving 55+mph on rough terrain for miles on Billsteins with 30,000+ miles on them... Any chance you over heated the shocks and they shit the bed??? Of course SOMETHING is going to fail. Honestly I would be stoked to lose a $70 bump stop in that situation over a bent LCA or cracked shock tower. Your expectations are unrealistic. In your opinion when are Gas Bump Stops needed? when do you start to think they are the realistic solution?? say over 45mph in whoops??

This isn't a pissing match at all, I am trying to determine what the most realistic cause could be because this failure has never happen before with this particular bump stop. I am interested in looking into potential improvements if I can determine that one is needed. Instead of sorting through the potential causes and FACTS of this failure I am having to sort through TWO COMPLETELY DIFFERENT SIDES OF THE STORY, Like Snowflake Kids. Just like I have already wasted my time to specifically explain to you through multiple messages on T4R "The reason your Durobump is chunking on your bolt head is because on a 3rd Gen 4Runner there is two bump stops per LCA. Our Durobump is only acting as a pillow in the rear of the LCA and still relies on the front OEM bump stop to provide the ultimate stop". You are exceeding what your FRONT OEM bump stop can handle (wouldn't be surprised if it has a split in it)
You also acknowledged on T4R (Funny no mention here on IFS) that you understood this 5-6 months ago when you replied by saying you were going to replace my provided JIS hardware with a button head Allen Bolt to reduce the bolt head height. But it appears you have forgot about that conversation. If your front OEM bump stop was not being over compressed there would not be an issue is the bottom line. This is why I keep repeating the fact "You are out driving what your current suspension setup can handle."
I know this from my own personal experience of doing the identical thing.

I am however working on a second Durobump that is intended to be installed at the front of the LCA that is much stronger than the OEM and in turn it would also not allow the rear Durobump on the LCA to chunk on the hardware from over compression. This development was in direct response to our customers who installed Durobumps being able to obtain higher trail speed with Durobumps installed. it became clear that there was a need to also replace the FRONT OEM bump stop with an Aftermarket that could handle higher compression rates.

The truck wasnt jumped when the bump stop failed. The passenger side. The driver side was fine and ran for several more days which included jumping it. It is still intact now. the passenger side is the only failure that happened

BULLSHIT!!!

Your friend (The actual Customer with the failure) directly contradicts what you are saying... I am honestly not trying to argue or cause any issues. I asked him what he did the day of the damage and he was straight up and honest about his day. I really appreciated that and said that I would "Absolutely replaced his bump stop set" Then after looking at the picture of the failed bump stop I could see that washers were used as spacers. He told me the washers were your idea... I explained that if I were to replace the set of bump stops and he installed them the same way that he could potentially have the same failure" Instead of lying and bullshitting him, I told him the TRUTH. He might be better with another bump stop brand and that I'll refund him in full. Our Durobumps are actually a fined tuned piece of art and by using spacers AND the High Speeds is what caused the bump stop to split. I already new this was a potential issue and that is why we do not offer spacers... (We do have a second size for this exact application BUT you thought you knew what you were talking about and you advised your friend in the wrong direction opposed to talking with a fellow IFS forum Member/Actual Manufacturer of the product.). All it would have taken was some communication .

All I have to work with is the information provided to me. Its clear that you guys drive hard and like I said to you on T4R I suggest Gas Bumps for the high speed and jumping you like to do. There is nothing wrong with how you like to drive, you just cant expect ANYTHING short of a Gas Shock to handle the that abuse. If your convinced that one of my competitors products is better PLEASE go try them out...

And one other Glaring issue with your story is you said the Bump stop "failed early on in poison spider mesa" Then you continued for several days jumping with only one good bump stop on the passenger side??? So with a failed bump stop you thought it was a good idea for your friend to keep driving like that??? What happen to the concern of protecting the shocks??? I would assume its obvious that a failed bump stop would also fail to properly stop the up travel and destroyed those 2.5 Radflos with the first jump... AND how is it that there wasn't any tire rub issues when continued jumping for several days on the driver side after the bump stop failed?

FYI - You are completely incorrect about RadFlo being comparable to KING. That's just ignorant. Radflo Is a good shock option above OEM, but they are not KINGS.

POUND SAND...

Adam the actual customer with the failure has actually been pretty cool and honest about it all. Then the cheerleaders jump in and stir the pot....

First thing I did was offer replacements, then realized how he was installing them and decided that a refund would be a better option for him because Durobumps installed the same way might have the same failure in the future. I feel this was good business practice and being the honest, stand up Gentleman that you all know here on IFS!

I’m think it’s so cool that this forum is a home base for so many innovative products and ideas. Like how we’ve watched durabumps grow from concept to where it is now , mad props. Also very cool to be able to get the ear of the ceo and asked questions, voice issues and suggest improvements. With that power comes the responsibility to not adversely impact the fundamental engine that allows such an awesome perk. Plastics guy’s stuff is top notch, I’m not being a blind fan. If I had issues as your friend does,with any product I’d follow up with company, through their proper channels. It looks like your friend is being taken care of and will have an amicable resolution. So why blast a product, you admitted to adding washers (changed) and then come here saying it broke and is no good?i read all the essays and that’s my retort.

 

[Theblackflag]

Like I said. Not gonna sit here and argue back and forth as the"3rd wheel" I was there when the bumpstop broke. I'm the one who fucking found it in his truck when I replaced the tie rod. You're acting like an irrational fool and not reading what I'm actually saying. Good public image for your company though.

Thankfully timbren has stepped up and approached both of us about running their bumpstops which I'm stoked about. Working with a company that has a no questions asked lifetime warranty and appropriately markets their product will be a welcome change.

You clearly have absolutely zero knowledge of how suspension systems actually work other than "I can throw money at coilovers and it helps" so take your rubber and shove it up you ass.

 

[4runner DOA]

Alright enough is enough. You don't wanna run them, then don't. @Plastics Guy has very much been forthcoming with his product and information regarding it. He's making the situation right with the actual customer, which is to be expected, and this can now quit.

Get hydro's. That's the only thing that will withstand the abuse you dish out.

LOL what!!! I found the last sentence to be a too funny.

"Good public image for your company though". DAMN strait son, @Plastics Guy did nothing but help out the customer that was having the issue and the customer who was just having personal issues apparently. ( also modifying its original orientation on how it was supposed to be mounted was kind of dumb and in my mind shouldn't be replace because of it being alter from how it should have been mounted on the truck BUT IT WAS what terrible Image I agree lol ) It might be because I'm not enough of a race truck driver and JUST SEND IT all the time guy but my 4th gen with the same bump stops (Duro Bumps front and rear) on 35's with icon 2.5 coil-overs w/ 14inch 700lb coils (Thanks to @4runner DOA ) don't have rubbing issue nor do I need to modify the spacing of my Duro Bumps not to rub just saying. Have fun with new foam towing bump stops lol.

How about we just stop with the pissing match. It doesn't make anyone look good and clogs up a thread with useless arguing.
