Lift??

[BookspanS]

Are rear leaf blocks and from spring spacers a safe way to get a little lift?

Since the MJ is SUO (spring under axle) a lift block will actually lower the rear.

 

The cheap/easy way to get lift out of the rear is to use a longer extended shackle. Coil spacers for the front. I wouldn't recommend doing anything more than 1.5" of lift this way though.

blocks only work for lift on a sprung-over vehicle. unfortunately, our trucks are sprung-under, so any blocks would actually lower the truck.

 

for our trucks, without being converted to sprung-over, the only options are extended shackles, add-a-leafs, or new springs. if you convert them to sprung over, you gain 4.5" to 6" lift depending on what kind of spring perches you use/make. at that point, I would highly suggest that you do not use blocks or spacers as they increase the likelihood of axle-wrap.
