Coilover Components
Coilover components include the springs, pillow ball mounts, camber plates, top hats, bump stops, and hardware that allow you to build, service, or upgrade an existing coilover system rather than purchasing a complete new kit. Sourcing individual components extends the service life of a quality coilover investment and allows fine-tuning of spring rates and ride height without replacing the entire assembly.Popular UpgradesReplacement coilover springs in progressive and linear rates are the most frequently purchased components, allowing spring rate changes to suit different driving applications without swapping the full shock body. Pillowball upper mounts improve steering response and reduce deflection compared to stock rubber upper mounts, making them a popular upgrade on track builds. Coilover lock nuts, spanner wrenches, and ride height adjustment sleeves are essential service hardware for ongoing coilover maintenance and adjustment.What spring rate should I choose for a street coi...
