Damn it! Was really hoping a buddy and I could finally come out and watch you guys race and pre run but I'll be shooting a wedding on Saturday. Truck's looking too good, best of luck to the Sherpa crew!

Ready for the Big Sky 200 with Ultra4 and Yellow Stone Offroad Racing.

Shocks have been rebuilt and revalved by our friends at Rockware with the help of Locked Offroad. Fronts are back to 8" shafts and now on a 800lbs spring.

Really excited to see how it rides. We are now also able to run much lower pressures in the shocks. Used to be running around 250 psi and current setup we are at 100psi. Excited to see how it does pre-running and mess with it from there.

Here she sits after some tom foolery.

Excited for this one, tune in this Saturday to The Big Sky 200 (Broadview, MT) North series | Ultra4 Racing to watch the race live!
Exciting stuff!

What's the reason you guys are running lower PSI in the shocks? I've always heard that higher PSI means less cavitation, which means less heat and less shock fade.
Curious about the nitrogen pressure too. How do you determine how low you can go?

We have experienced the opposite running higher pressures we have had major shock fade. After any extended run time, you can't even think about touching a shock body. With the current setup, there was literally no noticeable shock fade, I was blown away. You could also hold your hand on the shock body after over an hour of hard run time.

God damn she looks good.

Thanks man!

I'm curious why 800 lb coils in the front.

The 700lbs coils were nowhere near enough to catch this truck. We were blowing through them so fast. Even on the 800's with stiff valving we are going to add more to compression as we still find ourselves nosing in pretty hard on G outs.

Also where'd you get the rear axle hydro bump plates? Gonna need something like that when I deal with mine.

We made them!

Would have been awesome to have you out, catch us at the next one!

We listened to the wizard that worked on our shocks. 100psi worked great, we almost dropped the rear to 80psi to balance it out as the front was a bit softer than the rear causing it to buck every now and again.

Weird. I wonder if it has to do with higher pressures creating more damping force and turning the kinetic energy to heat faster. More heat = more shock fade. Maybe the lower pressures makes the shock less effective and generating less heat, leading to more consistent results.

lower pressure means less IMFs (intermolecular forces) = less friction and heat.

Yea our shock guy is wanting to go up to 850's but we want it to still handle the rocks well and get some slow speed up travel so pushing for stiffer compression and a slower rebound. Leaving the rear alone to see if it balances out with the front changes.

Sucks that your guys' class doesn't allow more shock than single 2.5" per corner. You guys are squeezing every bit of performance out of those 2.5's. Definitely some challenges to work through.

@Alex Fleming Just watched your KOH and High Desert 100 videos. Cool stuff and Way to go guys!! :usa2:




Shitty situation at KOH though, maybe next time :thumbsup:
Super pumped with how we did for our first year. It was a win to even be able to drive it back and on to the trailer after the abuse. Excited to be better off next year!

Well, the time has finally come. We have been wanting to get this suspension under the truck for a very long time.

We are in the process of installing the Marling Crawler +3.5" RCLT HD Long Travel Kit and some other goodies to continue to take this truck to the next level.

If you are interested in reading more about the kit go check it out here.
RCLT, Heavy Duty | Marlin Crawler, Inc.

But without further ado, here it is.

We opted to paint it with Steel It Coatings and are really happy with how they turned out.

Compared to a Total Chaos +3.5" Race arm

Started by gutting the front end. We also are having the diff rebuilt as we blew the R&P last race.

Lastly, prepping to finally add a quick release smaller diameter wheel!!!

More to come, cranking away for the YORR Columbus, Montana race on September 18th.

Got everything buttoned up. Not an insane amount of work. By far the hardest part was the steering rack as it required a good bit of modification to the motor mounts outside of passing the bolt through the lower control arm mounts.

Instead of plating the motor mount all back in, this was my quick fix to reinforce the mount.

Didn't want to rebuild our bump mounts, so we made a simple strike pad. This worked great.

We got all new factory hardware for everything that came out and needed to be reused. So new diff mounts/bolts, upper control arm bolt, and a few others.

Everything went back together smoothly. Everything looks great except the damn droopy headlights. Someone needs to make a stronger housing.
The ground clearance is awesome!

The front end handled great at the most recent race. Recap coming soon.

You might want to consider the dmz motor mount reinforcements. I think they offer more reinforcement than your workaround. My driver side sank into the frame.

They have to modify the perch for the steering shaft to clear. I don't think the DMZ kit would work.
