Serious 4/6 Drop Kit for 2003-2006 Silverado / Sierra Crew Cab
The DJM Suspension 4" Front / 6" Rear Complete Lowering Kit (Part Number DJM2999-4/6) is engineered specifically for 2003-2006 (2007 Classic) Chevrolet Silverado and GMC Sierra Crew Cab trucks. This kit delivers an aggressive 4" front and 6" rear drop while maintaining proper suspension geometry and driveline alignment.
Note: Designed for Crew Cab trucks with leaf spring eye hangers welded to the frame.
Up front, lowered control arms paired with factory coil springs produce a true 4" drop. Each arm comes assembled with new ball joints, urethane bushings, and twin tube pivot sleeves for simplified installation and long term durability.
Out back, the system uses an axle flip kit to achieve a full 6" rear drop. The kit includes pinion adjusting axle brackets, u-bolts, spring plates, thick frame reinforcement brackets for the required c-notch, a passenger side shock relocator, and all necessary hardware to ensure proper fitment and suspension travel.
Shocks are included to complete the suspension package and maintain ride control once lowered.
