The Bilstein 4600 Series rear shock absorber is the ultimate solution for owners of 1973-1986 Chevrolet C20 trucks who refuse to compromise on ride quality or durability. Designed specifically for light trucks and SUVs, these shocks provide a significant improvement over factory equipment, delivering a controlled, comfortable ride whether you are hauling a load or cruising the highway.

Legendary Monotube Performance

Bilstein’s 4600 Series utilizes a monotube gas-pressure design that keeps the shock oil cool and prevents aeration.

  • Monotube gas-pressure construction for fade-free performance
