1999–2006 Chevy Silverado & GMC Sierra 1500 4/6 Drop Kit – 2WD

Give your truck a low, aggressive stance with this Slamrite 4/6 lowering kit for 1999–2006 Chevrolet Silverado 1500 and GMC Sierra 1500 2WD trucks. Designed for V6 and V8 models, this complete suspension drop kit lowers the front approximately 4 inches and the rear approximately 6 inches while maintaining dependable street performance.

The front suspension uses 2-inch drop spindles combined with 2-inch lowering coil springs to achieve the full 4-inch drop. The included drop spindles help retain proper steering and suspension geometry, while the lowering springs complete the lowered stance.

At the rear, the axle flip kit provides approximately 6 inches of drop. A bolt-in C-notch with bump stops is included to increase axle-to-frame clearance and provide the suspension travel needed for a properly lowered truck.

Built from heavy-duty steel, this Silverado and Sierra 4/6 drop kit is a great choice for daily drivers, street trucks and custom builds that need a deep drop without an overly complicated suspension setup.
