Spring Shims - 1.250 OD .050 Thick

PAC Racing Springs Spring Shims 1.250 OD .050 Thick are precision-engineered suspension components designed for serious enthusiasts and builders who demand exact ride height and spring rate tuning. These shims sit between your coil spring and its perch, allowing you to dial in precise preload adjustments without replacing entire springs or resorting to crude spacer stacking. Whether you're setting up a road race car, autocross platform, or high-performance street machine, spring shims are fundamental to achieving the suspension geometry and compliance your setup requires.

The 1.250-inch outer diameter with .050-inch thickness provides the right balance of contact area and deflection characteristics for most coilover and traditional spring applications. PAC Racing Springs' manufacturing tolerances ensure each shim maintains consistent flatness and hardness, preventing spring binding or uneven load distribution that can cause premature wear and unpredictable handling. The compact .050-inch profile allows for fine-increment height and preload adjustments—stack multiple shims to achieve exactly the spring seat position your suspension geometry demands, without the guesswork of heavier spacers or the cost of custom-length springs.

Mechanics and builders working with coilover kits, double-adjustable shocks, or OEM spring platforms benefit most from these shims during corner-weight tuning and ride-height finalization. Compatible with most MacPherson strut, A-arm, and multi-link suspension designs, they're essential when fine-tuning spring preload in competitive environments or when adapting aftermarket springs to existing perches. Installation is straightforward—simply insert the shim between the spring and its seated perch, then torque to manufacturer specification. These precision components are ideal for suspension shops, race teams, and dedicated enthusiasts who understand that suspension geometry precision directly translates to predictable handling and longevity.
