4-Link Rear Suspension System

The RideTech 11387199 is a bolt-on 4-link rear suspension system engineered for 1999-2006 GM 1500 2WD trucks (including the 2007 Classic). The kit includes all necessary components for installation: upper and lower bars, a panhard bar, mounting brackets, and bolt-on C-notches for reinforcing the OEM frame rails. It features patent-pending R-Joint rod ends to prevent binding and noise, and is compatible with both RideTech CoilOvers and Shockwaves for adjustable or static ride height. This 4-link system provides a 6-inch drop at ride height, and up to a 9-inch drop when used with fully deflated Shockwaves. It enhances handling and traction by optimizing anti-squat, roll center, and pinion angle migration. This system is compatible with all cab size and bed length configurations for the specified 1999-2006 GM 1500 2WD models. CoilOvers or Shockwaves are sold separately and are required for operation.
