Chevrolet/GMC Silverado/Sierra 6" Suspension System 6 Lug 4WD 1988-1998

BDS Suspension Chevrolet/GMC Silverado/Sierra 6" Suspension System 6 Lug 4WD 1988-1998

This kit is based around new upper A-Arms, two one-piece, ¼” laser cut high clearance crossmembers and replacement steering knuckles. The high clearance crossmembers increase ground clearance for off road performance. Compression struts are included to support the crossmembers under impact. The replacement steering knuckles reduce installation time as well as maintain proper steering angles and ball joint angles. A differential skid plate is included for off road protection. Front stainless steel braided brake lines are included for optimum performance and to ease installation.

• Requires exhaust modification.
• Special tool (Kent Moore Tools Part #J-36202-A) required to unload/load torsion bars. Not available through BDS.
• Requires frame bracket modification and differential mount modification.
• Not recommended for long box extended cab models due to crossmember interference.
• All models equipped with auto-trac may require a new front driveshaft. The auto-trac New Process 246 transfer case can be identified by the silver dollar sized plaque on the rear of the transfer case that reads "NP246". The dash mounted display will display the Auto 4WD symbol. NP243 is not auto-trac.
• Aftermarket wheels required.
• System will not work on some '88-'95 vehicles equipped with spindle mounted front ABS sensor.
• Traction bars will not work on regular cab, short box models.
