Suspension

Whose droppin there silverados and what are you using.

i didnt do it to a silverado. but i just got rid of a 99 sonoma which i
slammed 3 inches.  i would recommend a Ground Force lowering
kit.  they got the thickest springs and in my mind the best ride.
i matched up the springs and the rear leaf spring block with belltech
nitro shocks and it rides as smooth as stock but handles much better.

did you go directly to there website or from a dealer. and how much was the drop

I got everything u need to drop it except for the nitro drop shocks on
ebay for $150 new.  the 4 shocks were 50 bucks a piece.  the
installation for everything i got done for about $180 from an owner at
a muffler shop.  but that usually runs 200- 400 bucks

well im sittin on 20". im wondering if a 3-4 would be too low cuz i dont have low pro tires(rubberbands)

well since the silverados have big wheel wells u shouldnt have too much
of a problem.  but yeh u would probably want to get that measured
out then
