DJM Suspension 6" Rear Lowering Kit (1999 - 2006 Chevy Silverado / GMC Sierra) - FK2599-6
Complete 6" Rear Drop with Adjustable Geometry
The DJM Suspension 6" Rear Lowering Kit - Part Number FK2599-6 - is engineered for 1999-2006 Chevy Silverado and GMC Sierra trucks, including 2007 Classic models. This complete rear system delivers a true 6" drop using a fully featured axle flip design combined with frame reinforcement and geometry correction components.
This kit includes heavy duty flip kit brackets with fully adjustable pinion angle, allowing you to dial in proper driveline alignment after lowering. C-notch brackets are included to provide necessary axle clearance and restore suspension travel at the new ride height.
New U-bolts and spring plates, bump stops, and all required installation hardware are included. The flip kit also includes a shock extender for the passenger side only to accommodate the factory staggered shock configuration.
Important: Your factory rear shock mounts are staggered, with one shock mounted in front of the axle and one behind it. This is why different shock part numbers are required.
Shocks are not included. DJM recommends:
Rear Driver Side Shock 1800 sold each
Rear Passenger Side Shock 1900 sold each
