Done a few trucks and worked out great I've tried other rear set ups but as always the 5305 coils do ride the best which has been proven on this forum for years and rear will not be way high like you see on the other kits out there.
My kit consists of
Belltech front drop struts and camber kit
Rear Belltech 5305 Coils
Rear Belltech Shock Extenders
Rear 1" Spacer
Rear Shorter Swaybar Endlinks
Rear Bumpstops for Free travel mod (manditory for 4.5 drop)
5/8 heater hose tubing (more on that...
NORCAL SS 1-2.5/3.5-4.5 2wd/4wd kit.
