I don't know about you guys, but I've broken off the stock rack mounts a few times now. My shit's way too heavy for the steering/skid plate layout that's pretty much identical to a 1G taco and 3G 4runner.
Minimum fix it adding a crossmember behind the steering rack to keep the tranny skid from tearing off the steering rack. That's boring. Why not add an external hydraulic cylinder to gain ~1000 LBs of steer force? This can also function as a rack-slider to help alleviate some of the stress at the rack and rack mounts.
Rough specs:
So far everything is floating where it needs to be. Initial cradle from sheet metal wasn't to my liking, so I'm starting fresh. Geometry is far from ideal. Fitment of everything is really tight and needs to allow structure around it and fitting access. Transmission pan isn't shown.
I think I tracked down all the fittings for the lines. Still unsure how much room i'll need at the rack high pressure port to do a 90 deg bend. Could end up with a custom fitting.
Dashed line is where the cradle goes.
Needs to somehow tie into the rack or rack mounting itself to prevent relative movement. Still working on a few options. As of now I have no way of reinstalling any kind of bellows over the stock rack. I think all the aux stuff will be fine, but the stocker needs to be protected from grit.
Now is when you guys poke holes in this idea.

Why not add an external hydraulic cylinder to gain ~1000 LBs of steer force? This can also function as a rack-slider to help alleviate some of the stress at the rack and rack mounts.
Rough specs:
- +1000 LBs of steer force. Stock should be around 1600 LBs+ manual contribution. This will end up at ~2600 Lbs of assist + manual contribution.
- Requires 60% more fluid flow, so it might drive like shit.
- Retains 100% stock rack for easy off the shelf rack swaps. No custom work or seals on anything that can wear out.
- Inner tie rods replaced with 3/4" heims, outers could be stock toyota outers or 80 series LC TREs (requires reduced droop travel)
- passive upper bar acts as rack slider which reduces vertical deflection of stock rack ~50% by initial simulation. Not as good as a purpose built, but not horrible
- Systems are synchronized with the beefy clevis adapters (green). They need to transmit high loads so they're pretty huge.
- Ties into stock sway bar mounts and also supports the transmission skid to avoid future damage
- No decrease in ground clearance
