Go Low with a 4/6 Drop on Your Silverado or Sierra

Take your 1999–2006 Silverado or Sierra 1500 with torsion bar suspension to an aggressive new level with the MaxTrac KS330946T 4/6 drop kit. Designed for torsion key front suspension models, this setup delivers a deep 4" front and 6" rear drop for a bold, slammed street stance.

This kit is built for trucks that want to sit low without losing drivability. By lowering the center of gravity, it improves handling, stability, and overall control, while still maintaining a smooth, near factory ride quality with the included matched shocks.

Up front, drop spindles combined with torsion keys achieve the full drop while keeping suspension geometry in check. In the rear, the flip kit and shackles provide the full 6-inch drop, while the included C-notch and shock angle corrector ensure proper suspension travel and alignment at lower ride heights.

Constructed from heavy-duty steel and finished in a durable powder-coated finish, this kit is designed for long-term performance. It comes as a complete package, making installation straightforward with all major components included.
