The kit was from YotaMasters and yes, its long enough.

Better question is, is it too long and going to break his t case again?
I was very specific about the collapsed length when I dropped it off with my driveshaft guy. We don't want another T-case explosion mid race!

Did you account for bushing and spring deflection when hitting stuff at speed? I'd imagine that you could push the axle back another inch or maybe even 2 vs just flexing on a ramp.
I'll also agree that slip looks awfully short.

That kit looks identical to the kit I just built from Marlin.Throwing in some fresh spark plugs and got the parts to make a spare front driveshaft.
We have shirts and stickers for everyone helping out in the pits. Shoot me a message - I'll send you a shirt after I've handed out crew shirts.
Not when I installed the new housing. I put the truck at full bump, did some ghetto math to account for the bushings and got the new full bump measurements. The current pinion flange to pinion flange measurements that we have are accurate. I still think that the TG housing moved the pinion back slightly, bottomed out the drive shaft in the whoops and killed the t-case.
The new drive shaft has about 1 1/2" of spline engagement when the truck is on the limit straps.
4653 waiting to be loaded in the trailer.
It probably is the same. I will try and buy it directly from Joint Fuji next time. Welcome to JOINTFUJI.COM

Pitbullcruiser setup looks great and safe travels. Really like the usage of the maps inside of the trailer.

Any updates? how was the race? I tried to watch the live stream at work a little bit but didn't catch you on camera.

Broke rear diff and stripped splines in a driveshaft around Race Mile 60.

Bummer, especially with the thorough prep and maintenance this rig sees! Curious of the breakage details...

I'm surprised he's still running an 8" rear, axles are unlimited, so why limit yourself with a tiny axle? And also not surprised that cheasy slip stripped out.

i thought you had to stay with in the family, like toyota 9.5 or tundra 10.5 but not dana 44 or 60 i could be wrong though.

Totally wrong, axles and tcase are unlimited. He could run D80s or spider 9s if he wanted to.

stock style suspension and motor are the requirements for emc stock class?

Correct. Then an insane amount of limitations for body, frame, and firewall requirements too.

I'm not trying to be the authority on 4600 rules, as it's pretty complex. But as far as I understand, axles and tcase are basically unlimited, and everything else is pretty limited.

after i read awfawk s comment i remember reading that part. i think when i read all that jazz was when justin won a few years back, saw he had a diamond front i think and just assumed all that was under the stock style BS rules. and never thought to use a dana or anything.
but yeah fuck it all to hell and get 35 spline 9 inches and fab housing and call it a day.

KOH 2023 Race recap!
We got to the lakebed and setup with our 2 other teams. We started the week off pre-running a few rock trails, trying to get up the lap 2 sand hill and pre-running portions of the desert lap. During pre-running the primary fuel pump died and wouldn't allow the engine to go over 3k RPMs when in gear. The fuel pump was swapped out with the backup fuel pump and pre-running resumed. A new spare fuel pump was ordered and picked up in town a few days later. After passing contingency we headed back to the garage and prepped the truck for the EMC race.
Race day we got the truck staged early, drank some coffee and got ready to go. The 4800 cars start moving and that is the signal to get the helmet on and get strapped in to the race truck. We made our way to the start line and 3, 2, 1, go! We were off the line and moving towards the sand hill on the backside of Backdoor. We made it up the hill first try and headed down to the lakebed. We made our way through the desert to Remote Pit 1. At RP1 we got a visual inspection, took some fuel and got moving again. Around Mile Marker 45 the rear end started making broken differential noises. We pulled off course, got out and inspected the damage. We determined the rear diff was broken and decided to keep going in front wheel drive. We were still moving at a decent speed hoping to make it to the Main pit and swap out the diff. Around Mile Marker 60 the splines on the female portion of the front drive shaft stripped out. We coasted off the race course, got out, determined we were out of the race, called it into Race ops and waited for a tow. Race Ops got us towed off course and to a spectator area. A guy form our crew towed us back to camp and we started to do a full inspection of the damage. Most people think the diff broke from driving in 4WD through the desert whoops. We put the spare front driveshaft on, got the truck and all the gear loaded up and started prepping for the 4400 race the next morning.
Overall we had a great time and cant wait for the next race in May.

Thanks for the recap. Curious what caused the front splines to strip out like that.
