Hydraulic Steering Damper Kit for 1979-1986 GMC and Chevrolet K-Series Half-Ton and Three-Quarter-Ton Trucks
The Skyjacker 8055 is a hydraulic steering damper kit engineered for 1979-1986 GMC and Chevrolet K-series trucks, including the K1500, K2500, K5 Blazer, and Jimmy. The square-body GM platform from this era is a beloved foundation for both restoration builds and trail rigs, and the 8055 addresses the shimmy and steering wander that develops on these trucks after suspension lifts, larger tires, or simply with age and wear. The 8055 bolts directly to OEM mount points for a clean, factory-style installation.

FAQ
What is the Skyjacker 8055?The Skyjacker 8055 is a hydraulic steering damper kit designed for 1979-1986 GMC and Chevrolet K-series trucks including the K2500, K1500, K5 Blazer, and equivalent models. It reduces shimmy and steering wander by mounting directly to OEM locations on the front axle.
Does the 8055 fit a 1979-1986 Chevy K10 or K20?Yes. The 8055 is compatible with the 1979-1986 Chevrolet K10 and K20 (and K30) trucks built on the same square-body GM full-size platform as the GMC K1500, K2500, and K3500 models.
Will the 8055 work on a lifted square-body truck with bigger tires?Yes. The 8055 is an appropriate upgrade for square-body GM trucks that have received suspension lifts and larger tires. The hydraulic damper absorbs the increased steering forces generated by larger tires and caster angle changes from a lift.
Does the 8055 require any brackets or adapters to install?No. The 8055 uses the existing OEM steering stabilizer mounting points on the 1979-1986 GM front axle. All hardware is included and the installation requires only standard hand tools.
What warranty comes with the 8055?Skyjacker backs the 8055 with a lifetime limited warranty for the original retail purchaser covering defects in materials and workmanship, excluding competition use and commercial vehicle applications beyond one year.
Is this part hard to find for 1980s GM trucks?Skyjacker still supports the square-body GM platform with purpose-built part numbers like the 8055. Aftermarket support for these classic trucks remains strong, and the 8055 is designed as an exact-fit replacement for these specific applications.
Does the 8055 contain Prop 65 chemicals?Yes. This product contains chemicals known to the State of California to cause cancer or reproductive harm. A Prop 65 warning label is included with the product.
What is the correct Skyjacker part number for a 1985 GMC K2500?The correct part number for a 1985 GMC K2500 steering stabilizer is Skyjacker 8055. Always verify the fitment year range and your vehicle's drivetrain configuration before purchasing.
Installation Instructions
