Shock Absorber B6 Rear GM K1500 / Suburban

The Shock Absorber B6 Rear GM K1500 / Suburban from BILSTEIN is a premium monotube shock designed specifically for full-size GM trucks and SUVs that demand superior damping control and longevity. Built for owners who push their K1500 pickups and Suburban platforms hard—whether hauling heavy loads, towing, or navigating rough terrain—this rear shock replaces worn OEM components with tested performance engineering. BILSTEIN's 4600 Series shocks are engineered to restore lost suspension responsiveness and improve ride quality on vehicles that factory shocks can no longer adequately support.

Constructed with a robust steel body and finished in BILSTEIN's signature yellow paint, this monotube shock absorber delivers consistent, fade-resistant damping across a wide range of operating conditions. The monotube design eliminates the complexity of twin-tube architecture, allowing heat to dissipate more efficiently and reducing the risk of performance degradation during extended use. At 5.05 lbs and measuring 26.75 inches in length, this rear unit is engineered to work in harmony with properly matched front shocks to deliver balanced suspension geometry and predictable handling characteristics that OEM shocks often fail to maintain after 80,000+ miles.

Mechanics and enthusiasts upgrading full-size GM platforms benefit most from this rear shock when replacing both front and rear units as a complete system, ensuring uniform damping response across all four corners. Installation is straightforward on 1992–1999 GM full-size trucks and SUVs, though professional installation is recommended to guarantee proper alignment and torque specifications. Whether you're restoring aging suspension on a high-mileage Suburban or enhancing the ride quality of a K1500 used for towing, the BILSTEIN B6 rear shock absorber delivers the durability and performance control that OEM components cannot match after years of service.
