On a 88 k5 can i safely run a 2" adda leaf in the front and back running 33x12.50 on 15x10s with no trimming and street driving...just the occasion street curbs and snow weather... If it has a helper spring in the back am i right by saying that i will need to run a 2" block in the back if it already has a spring ?? edit: and will i have to do nething to the steering? or anything longer shocks??
