Product Description

The QA1 R245‑200 Rear Coil‑Over Conversion System is engineered as a premium upgrade for 1999–2006 Chevy Silverado 1500 and GMC Sierra 1500 2WD short‑bed trucks equipped with the GM 10‑bolt rear axle. This kit replaces the factory leaf‑spring layout with a torque‑arm multi‑link system and high‑performance coil‑over shocks, delivering improved ride quality, stand‑alone adjustability, and better traction under load.

Featuring double‑adjustable coil‑over shocks with 18 clicks of independent compression and rebound tuning, the system gives drivers the ability to fine‑tune ride and handling from comfortable daily driving to aggressive performance use. Additionally, the design supports an approximate drop of 4″ to 7″ for a lowered stance while maintaining proper geometry and clearance.

Installation is simplified thanks to the bolt‑in fuel‑tank crossmember and included hardware, eliminating the need for welding or major fabrication. Perfect for owners looking to combine show‑truck aesthetics with performance hardware, the QA1 R245‑200 offers a full rear suspension transformation—just be sure your truck meets the 2WD short‑bed specification and GM 10‑bolt axle requirement before ordering.
