Builds Box Rocket 1995 FZJ80 Build (2 Viewers)

I completely agree - Keep them torqued correctly an you'll have no issues. I usually recheck after first install after 500 miles and a few heat cycles. Not sure weather I've been lucky or diligent, but never had issued including years running 44s and 800+HP with a ton of quench cycles through water/ mud.

If you check StreetSpeed's YouTube channel he stacked 8x cheap spacers on each wheel and installed 44" boggers on a new TRX - flogged the hell out of it and never had any issues (at least not with the spacers). I've seen desert racers run spacers without incident as well. Pretty good endorsement in my mind.

(I'll stop hijacking Adam's thread now)

Good stuff. No hijack.

How long did it take to stitch the wheel. I think mine comes tomorrow.

About 3.5 hours start to finish. But I’m sure it could be done faster.

did you pull the wheel first? Or do it sitting in the driver seat the whole time?

I did one years ago, pulling the wheel is the way to go!

Same Kit as Adam? How has it held up?

I did not pull the wheel. Wasn’t bad. I had a game on the TV in the garage that I could watch while I worked.

but pulling the wheel could make some of it easier. Probably won’t change the stitching time much and will add a little time to remove the wheel so plan accordingly.

Hit a 2' ditch at 65mph on a recent trip. Suspension handled it just fine. The hinge spindle on my bumper didn't handle as well. I can't complain though, I built the bumper 16 years ago and it's had more than 100k miles of use and abuse with either a 35 or 37" spare tire on it. Fortunately, our group was a little spread out so when it came off it didn't create a dangerous situation. It ended up 30yrds or so off the road after it fell off and bounced into the weeds.

The bumper was still completely fine, there was no failure of any welds. The spindle just snapped at a stress riser where the spindle was machined to step down to a narrower diameter. We found the broken spindle and you could see that it had developed some cracks already sometime in the past and there was only about half of the spindle that was still intact.

I got it fixed up this weekend using a 4xInnovation double shear hinge. This hinge looks like a really strong piece and I'm hopeful that it lasts another 16 years. The hinge outer tube was slightly different so I needed to cut the end off the swing arm and modify the arm a little. The arm is all built from 1/4" tube so it's strong (but heavy). I needed to add about 4" to the arm length so I sleeved the arm and added another section of 1/4" tube and welded them together using rosette welds as well as the joint itself. I think its a strong repair. The hinge worked out well. It's got two roller bearings with sleeved stainless inner sleeves with a 3/4" grade 8 bolt as the hinge pin.

Had to do something similar over the summer. Nothing broke but the terrible hinge that was used seized up despite all the grease I put in it. Turns out the original designer put one geese port inside the bumper and removed the zerk

I thought about this event today as I was rapidly moving through the Gila National Forest in NM. Look for the holes, look for the holes!

Looks like you were having fun out there.

Fun was definitely had! Awesome trip. I’ll post more from the trip later.

Heavy weight rally cars…how can you not have fun!

Dang! that sucks.

It never seemed like a great idea to load a 100 lb+ tire carrier off a single shear spindle, but that's how almost all of the bumpers on the market are built. Double shear makes a lot more sense if you can brace the top tang enough to make it rigid.
