Im thinking about some 37/12.50/18 pro comp xtreme a/ts for my next tires. If I do so I will need some longer control arms made, but how much longer do they need to be? Im just running three inch blocks in the front. I will also be putting on some new wheels but I like the wider look so I want them have as little of back space as I can. Anyone have any input?

Thanks Joel

 

4.5 to 5" of lift with 5.5 BS on a 8.5 wheel with a 37x13.5 is as close as you are going to cut it.

I have tuff country CA's....maybe just a 1/4" shorter than those might work with 3".

 

top gun customz will make you a set for $240. that's the route i just took, waiting to get them.

 

Just to give you a reference, stock arms are are:
Upper: 16 5/8"
Lower: 18 5/8"

 

Carli's are 1/2 " longer. They have two grades of arms.

 

Thanks guys. I may have to throw some on and see what happens. The wheels I have now are 9 wide with 4.75 BS and they dont rub anywhere with 35s. I bet its gonna be close even with new CAs.

 

Call Mike at LazarSmith, I saw the one's he made for his truck and they are sweet.. Not sure if he makes them for the public, need to check out his site, but they definately are nice.

 

37x13.5 on 4.75 BS will tear your fenders off unless you have 6-8 inches of lift and NO travel.

 

Yah I wouldnt put them on my present wheels. I plan on new ones with more bs.

 

I usually go 1/2" longer with leveling kit-range lifts (2-3").

Backspacing is a tradeoff between losing lock-to-lock steering and rubbing the plastic fenderwell & chin fairing.
