Chevrolet/GMC 1500 Pickup 4WD 4" High Clearance System
Rear Leaf Springs
This new high clearance design is a true blend of performance,
appearance, and function. The suspension geometry creates an
OE style ride
with a desert racing appearance. These high arched crossmembers
blend perfectly with the lower control arm angles to give a truly
OE appearance while lifting your vehicle a full 4” and increasing
ground clearance at the front crossmember by 91%. The custom valved
front BDS struts are designed to handle increased tire & wheel
weight, without sacrificing ride quality. A new front skid plate
and differential skid plate are included for extreme off road
protection. This option also includes new BDS Glide-Ride rear leaf
Strut compressor required for installation.
This system will not fit 2007 Classic models.
Installation of the optional rear leaf springs requires removal of
the fuel tank.
Requires frame bracket modification.
Less trimming is required if 20" x 9" Wheels with 5-3/4"
backspacing are used.
Denali/AWD models will require a new CV style front driveshaft.
Will not fit 2009-2011 Two Mode Hybrid models with Electronic Power
