Why can't I put a lift block on my cherokee in between the leaf springs and the axel and Chevy Pick-ups can?? My dad has tried asking the same question and he got "It's just not a good idea" and thats all he got, I can understand all the torque but Chevy pick-ups have 2-3 times more torque than a Jeep does. Why can't I do it?

 

The rear springs in a Cherokee are too thin and soft, they don't have a real overload spring, like a truck. You can do it, most companies sell block lifts for Cherokees, it's just not the best way to go. DO NOT use blocks over 2". Trucks may have 2-3 times more torque, they also have 2-3 times thicker spring and spring ratings about 500-700lbs vs 1100-3000lbs.

 

my buddie did that to his old skool cutlass to fit 23"s on it.worked fine for that.not sure about off road stuff..

 

you can do it its just not something that I would personally recommend for any vehicle as it will make the leafs want to sag worse then with out them.
get aal or new leaf pack and there are some budget ways to get a lift if your tight on money like most of us are

 

sure you can a 2 or matbe 3" budget lift, block on rear and spacers on the front, make sur you get longer shocks though

 

you can

but shouldnt

more axle wrap
more wheel hop
leaves will sag quickly
driveshaft can separate
some lift blocks can break

 

I just finished removing the 1 inch block that was in the rear of my Jeep. Even that tiny little 1 inch block was causing my axle pinion to move up 3 inches on a normal take off. I can only imagine what it did under hard acceleration. While I was removing them I realized the centering pins for my leafs were severly bent and needed replacing. To better explain the excessive force that blocks create on your leaf springs. Think of trying to remove a rusted seized bolt with a standard ratchet. It can be extremely difficult if not impossible. Now put a 3 foot piece of pipe on the end of the ratchet so you can apply more force with less effort. That is why blocks are bad on your springs.

 

alright thanks guys. yeah i have always wondering y it wasn't really able to do it.
