Kurtis T4R Build Thread

So....I have been busy lately. The rear frame chop is complete. Shock towers are in place along with ORIs. Front axle is fabricated, gears installed, King Pins replace, knuckles rebuilt, and double ended ram mount installed.

At ride with trail tire pressure we are looking at a frame height of 21.5"/22.5"-ish with 5" of up travel in the front and 6 " in the rear. 4 link in the front was successful but exhaust is going to be a pain in the ass with all the up travel. The wheel base came out at 109". Front is 82.5" wide and rear is about 79.5".

I had to preheat the 60 diff housing to 400 degrees to weld on it. I had to use Nickel-55 welding wire, which is stupid expensive. But it should be plenty strong.

It's getting closer to being done. I think it should be done by the end of September. I have 6 months to make up in abuse to this thing.

Next on the chopping block is:
-Steering pump/Finish steering
-Finish skid/Trans Mount
-Fill ORIs with Nitrogen
-Drivelines
-Brakes (Cutting/Line Lock)
-Exhaust
-Wiring for moving the battery to the rear/Air line routing for ARBs
-Fix some clearance issues
-Beat the shit out of it

Full bump





Still need to do a bit of clearancing here.





The Dana 60 tucks up nicely here.



Wiring is going to be a zoo. I got rid of a lot of those accessory things.



Front strut mount. No strut bar for the front. It's not needed for how I did this.



Orbital valve mount for the hydro steering



Testing clearances during fabrication. Full droop.

The Tamers is my club. Awesome people.

I got interviewed at the Expo because of my truck. There will be a couple videos coming out with my 4Runner in it. I will post them here when they are published.
 
How do you find the 5.29's/5 speed off road? Im running stock 4.10's with 33's and its my biggest complaint about my truck. Im constantly riding the clutch to prevent stalling. I've been researching and planning a dual case setup. I feel my gearing is limiting me way more than the ifs.

I run a different set up now. But previously I ran 5.29's with a 35" tire. Even that was a bit much for highway driving. 4.10's are about where you need to be if you are wheeling a 33" tire. The next set up is 4.88's but I wouldn't recommend regearing just for 33" tires unless you really hate your wallet. Doing a doubler t-case setup will help a ton. Before the 4Runner I had a Toyota P/U with a doubler. It's fantastic.

Yeah I find the 4.10's quite comfortable on the road. I wouldn't really want any lower gearing on the highway. I was just curious how you liked wheeling with low diff gears and the stock t-case.
A second T-case would be the answer for me. It doesn't seem that hard or expensive either. Im trying to find a 23 spline gear case (I know they are rare) so the only major cost would be the adapter plate kit. I can make/modify everything else myself. It surprises me more people don't do duals on 3rd gens.

Looks like a pretty cool club! I saw your rig pics from the expo and the reiter video. Damn sweet man!

Thanks dood. There should be a couple professional videos coming out soon. It's going to be strange to see my 4Runner in the videos.

Trail riding is fine with the stock t-case. It's when you get into places that have obstacles very close together that started to annoy me more than anything. Trails with big rocks are a little more difficult but it can be done. There isn't a whole lot of people that really wheel their 3rd Gen 4Runner. Most go for the occasional fireroad or overland stuff so there really isn't a need for a crawl box. And don't forget about changing drivelines. That can be spendy.

True. Though there are guys out there who have proven that you can wheel these trucks pretty damn hard with dual lockers and the stock ifs

I have a lathe so was just going to machine stepped inserts to match the inner and outer diameters of the driveshafts and just weld them in and balance if necessary. Unless I'm missing something, it seems fairly straightforward. My only concern is that with the rear output being moved back ~8" combined with my 4ish" of lift in the rear, the driveshaft is going to be at quite an extreme angle compared to stock.

Dude, I've apparently missed a lot lately. I never knew you flopped your truck. Looks like you're taking care of it the right way. Sweet progress.
