Post 35" Tires

I have got a 1985 CJ-7 with 31" tires on it now, and want to run 35 x 12.50. How large of a body and suspension lift am I going to have to get to make the larger tires fit without rubbing.

85 CJ-7, 350, T-18 Tranny, Dana 300 Transfer Case, Solid Moser Rear Axles with Detroit Locker, 4.10 Gears, 2-1/2" Suspension Lift & 1" Body Lift, 33" Cooper Mud Terrains.

Well, first....think GEARING. Make sure your gearing can handle 35" tires. In the 80s, Jeep CJs sometimes had as low as 2.73s in them, which are marginal even for 31" tires. Most of us with CJs can GET AWAY with 33" tires with 3.54 or 3.73 gears, although 4.10s are ideal. 35" tires should really be run with 4.56 gears to be "comfortable".

Anyway, that aside, without rubbing, you will need a bit more than 4" lift to comfortable fit 35" tires. I have between 5-6" lift on my '77 CJ-7 and could fit 35", but am going to stick with 33", as I don't feel like regearing right now, and don't want to overstress my stock axles. So, my advice is to use a 4" suspension lift, coupled with 1-2" body lift, but NO MORE than 2"! That should get you to a comfortable height. Be prepared to make adjustments (clutch bracket, steering shaft, radiator, gas filler, e-brake cable, etc.). It does involve some work, it won't simply be a "bolt-on-and-go" application.

Good Luck, and keep us updated! <img border="0" title="" alt="[Wink]" src="wink.gif" />

here is how I am set up no body lift spring over and a 2.5" sus lift 1.5" shackles and running 36 12.50 with no rub now.. I didnt really have any rub before with out the shackles... and then I also turned my CJ into a flat fender to get a bit more space in there for really good articulation so all in all I am running about 8 or 9" of lift
82 CJ7 36" superswampers. SOA ,2 1/2 inch lift springs and a whole lot of dreams. My baby.
