Has anyone thats used these ever run into problems? thinking of levelling the back of a new 4x4 which from what i read is about 2"

 

I put some Bell Tech 2" drop shackles on my 2wd. Leveled the truck up nicely. I really like the look. Ride completely uneffected. I don't load my truck up heavily, so for me, no effect on utility either.

I did have to re-aim my headlights lower, though. Everybody and his brother would flash me, even though my brights were not on.

I do not have the 4wd, but others on the forum might know if you can level your truck just by removing the block between the leaf spring and the axle.
