Fitting 35’s with minimal trimming NOW ADDING LONG TRAVEL AND 934 CV’s

That really makes me want to talk to a few people about making a bullet proof ADD shaft. We have a place here in Michigan that will machine 300m shafts for anything.

 

I havent heard of many people blowing up the solid FJ ADD, and im not sure if it would be worth it to upgrade past that. You gotta have a weak point somewhere and i wouldnt want it to be my diff.

 

The shock from the shaft breaking is likely what pushed his diff over the edge. That shock alone is likely what spiraled it all out of control. People need to stop thinking about “fuses”. They don’t exist. What breaks, breaks. The goal is to make it all strong.

And personally, I kinda like having the ADD. It has its benefits. So if it can be made stronger, why not?

 

But 2lo is rad and so is that stick shift into place with no worries about when it will or will not unlock

 

Those fuses are just not wanting to actually put in the effort or $$$ to upgrade and make it stronger.

 

I’m already twin sticked, and I have yet to have one single issue with the ADD. And coupled with the twin stick that ADD button allows you to do some cool things. Like put power to one tire and one tire only up front. Which has proved to be very nice in some situations.

 

Yes his probably broke from shock, but mine did not. I rarely bump anything and i try and be very smooth with my truck, yet i still blew up my front ADD. In a race application i would agree with you, build everything as strong as possible. But for a weekend warrior, its easier to replace a $200 ADD tube rather than a $2000 diff.

I think @Tacoma1192 already looked into 300m shafts. Maybe talk to him if you really want to go that route. Theres also other issues with the stock ADD, the plastic teeth on the motor can break, are you going to upgrade those too?

 

Actually, a buddy is already designing a full mechanical actuator like the jeep guys used to do when the vacuum ones failed.

I like to improve the things that are convenient not delete them because they have their problems.

 

Seems like alot of work to still be limited to the factory 8 inch diff.
When designing parts like this, there needs to be a market for them. A 300m shaft is a great idea, if there is a need for them. Seeing that you havent had an issue with it, and there arent many people that have had issues with them. And theres a solid upgrade to the fj tube, i dont see a market for it.

 

Currie 9” center mount diff. That’s my plan until @81Trekker does some thorough testing of the ttb kit. 2-3yrs from now my truck will be under the knife and for some very serious work. Borderline tube chassis build hopefully/ unfortunately for my wallet. Luckily as we’ve seen the wife is cool with these things

 

Doesn’t need to be a market when you’re not planning to sell them. Not everybody needs a 200k$ truck. And many do appreciate improving the factory weak points.

 

Is the lower arm pivot still what would provide the best solution I'm looking for? I suck ass at alignments in the driveway and I've already chewed the shit outta 2 35s, my steering is whining like a house cat stuck outside too. Tires rub the F outta all the sheet metal things!
Just wondering if I should get a mid-travel arm kit and gusset the LCA area as seen from Marlin/TC, instead.

Tell me what to buy damn it! lol

 

Going to an MT kit and adding gussets won't solve any of your main complaints. The JD lower pivot kit was designed to allow you to move the tire forward to minimize rubbing with bigger tires and strengthens everything in the process.

That and the Howe pump upgrade and you'll be in a much better position than doing the MC kit with a standard MT setup.

 

1000 thank you's!

Never going back to 33s, btw

 

The pivot kit solved all my 35's rubbing issues and i have all the caster now. Do it.

 

My LCA pivot kit is out for delivery as we speak. If I can possibly make the meet up at rush, you'll be able to see it 1st hand and go from there.

 

Seriously, everything in this link will solve all your problems.

Yeah, I know it lol

 

Plan to have it before then. My front end feels really fragile tbh

 

Hit me up when you do it, hopefully I'll have mine done and can help if you have any questions
