Ultra4 4628 Race car - Sherpa Motorsports

Looking forward to KOH and seeing your truck in person.

This thing looks amazing

The team made some amazing progress over the weekend.

First, we got the rear axle and 4link finalized and installed. We started with coil perches, shock mounts, and hydro strike pads.






We are running bent upper links to clear the factory cross-member as we are not allowed to cut it out per the class rules.

We mocked up coil placement after cutting and planting the truss.





Then started the shock placement.






Then, hydro bump pads.


Then got the axle full welded and prepped to paint.

The 200 series rack is getting ready to go in as well. We started by removing the factory bushing to have our offset spacers machined. The hole spacing needs to change about 1/2" to fit the 4runner frame.




So, that is off having the parts made, should have them back sometime today actually.


Stocked up on a bunch of fluids for the truck.


Got the roof rack ready to rock as well. We gotta do some marketing so threw some Maxtrax on the rack (which may come in handy) and a rotopax for show.


Replaced our final original bump stop mount.



Painted these.



Installed our Yukon Air Compressor


And here is where she sits. Front end comes Wednesday... hopefully.



There is a lot of other small things we have done that I don't have pictures off such as more cage reinforcements, wiring, took all the decals off to prep for a wrap, and a whole lot more.

That is some amazing work! Can't wait to see it in action!

Forget bulletproof, that rear axle is bomb-proof.

Another very important piece to the 200 Series Land Cruiser rack swap.

Black Peak Engineering whipped up these new bushing replacements "Solid Spacers" for our steering rack to bolt into the factory location on the 4runner.
These are made to the exact spec of the factory bushings but offset to line up with the 4runner frame, they are press fit and made out of 7075 Aluminum. Thank you, CNC Mills.

amazing build and progress. Can't wait to see this complete. It's going to be one hell of a t4r..

I'm sure you guys are busy but could you elaborate a little more on the 200 series front rack and pinion?

Other than the offset spacer aluminum bushings and maybe some minor plumbing, did you have to do any other custom stuff to fit it?

Inner and Outer TRE's mate up fine?

Do you think the solid aluminum spacers will cause the rack to wear faster? Or?

It's a bit of trial and error over here. So far it looks like everything is just going to work as far as plumbing goes. As far as the tie rods we are using the inners but making the outers out of DOM tubing and a hiem joint on the spindle side. So using a but welded on the inner side and a jam nut to allow adjustment just like factory but way stronger. On the spindle, we are doing a double sheer mount.

The solid mounts will definitely be harder on the components.

Tonight is the last night before the 4runner is loaded up and headed out to California to get wrapped, fiberglass installed and buttoning up a few loose ends.

Here is what we have finished.

First, the front suspension, steering, front diff, and everything that goes along with that.

The arms are from Total Chaos, it is their +3.5 kit. We ended up having to run the 8" Coilover again as we couldn't really get the 10" to work without need a coil compressor to install and uninstall and we did not want to deal with that on the lake bed if we had to pull it out for some reason. The 8" will still work amazing but hope to get the 10" to work with maybe a shorter shaft down the road.

We made our double sheer steering and hiem setup, this was hard as the misalignments we got were not right and we had to get creative to get our travel back without binding the hiem. This isn't ideal yet and definitely stole some down travel from us. Still way stronger and will work. Also, drilling out spindles suuuuuuucks. We upsized to a 3/4" bolt which was awful. We may end up sleeving this and running a smaller bolt to get more misalignment in the future.

The front diff, steering rack and oil pan are all really tightly packed now. It's extremely tight with the 200 series rack in there but it works.

We also swapped the studs on the front to match the rear axle.

Here it all is together.





















Its wide...







But, all the wiring is finished, diffs are in, the rear axle is done, custom brake lines are all done (that was a big project), new window nets, new limit straps front and rear, intake is in, new radiator and hoses, fluids changed and a good bit more of random things.

We have a decent list of things to knock out tonight then it's off to Beyond Wraps for some tasty vinyl goodness.

Badass work guys!!

Sherpa!! #4628

Watching in between work, spicy unit spotted

Still racing

I’m really hoping there’s a good write up on that 200 series rack install I’m wildly interested in it

What is everyone watching this on tomorrow ??

I think they ran out of time. They were stuck in the rocks with about 4 or 5 other cars that hadn't moved for close to an hour.
Last I saw was 12th in class.
Edit: Only 2 finishers in the stock class. By all accounts, even the desert section was brutal this year.

Thanks for following along with the race and our progress! We have a full race recap and photos coming soon!

We did not finish, but I would count what we accomplished as a great success and puts us in a good position for the rest of the season and next year!
