16mm Shock Shim Starter Kit

The 16mm Shock Shim Starter Kit by Allstar Performance is engineered for serious suspension tuners and performance mechanics who demand precision control over shock damping characteristics. This kit provides the foundational shims needed to begin customizing shock absorber valving, making it essential for drag racing, circle track, and street performance applications. Whether you're fine-tuning compression or rebound damping, this starter package gives you the core components to dial in your vehicle's suspension response without purchasing full assortments you may never use.

Shock shims function as precision valve components that regulate oil flow through shock internals, directly controlling how quickly your damper responds to suspension input. The 16mm diameter format is standard across many high-performance shock designs, allowing users to stack and layer different shim thicknesses to achieve desired spring rates and dampening curves. These starter-kit shims are manufactured to exacting tolerances, ensuring consistent performance and repeatability across multiple shock rebuilds. The compact 5.5 x 1.05 x 9.05-inch package is space-efficient for shop storage, and the modest 0.26-pound weight makes this kit ideal for transportability between shop locations or race venues.

Technicians and enthusiasts rebuilding coilover systems, off-road suspension setups, or competition shocks benefit most from starting with this kit before investing in full shim assortments. The 16mm size is compatible with popular performance shock platforms used in circle track, drag racing, and road racing vehicles. Installation requires basic shock disassembly knowledge and proper valve tools, but the starter configuration provides the flexibility to experiment with shim stacking before committing to larger, more expensive packages. This kit represents smart purchasing for mechanics developing their valving expertise or for first-time shock builders seeking proven Allstar Performance quality.
