14mm Shock Collar Shim Kit 1in 2pk

The 14mm Shock Collar Shim Kit 1in 2pk from Allstar Performance is designed for suspension tuning on race cars, street performance vehicles, and high-end sports cars where precise shock damping control is essential. This kit allows users to modify shock absorber collar geometry without the need to replace entire components, making it ideal for both professional and amateur tuners.

Constructed for durability under high-stress suspension cycles, the shims work by altering the effective collar seat surface, which changes how the shock spring nest sits and loads under compression and extension. The shims have a diameter of 14mm and a thickness of 1 inch, allowing for controlled adjustments to ride height, spring preload stiffness, and shock response characteristics without modifying base valving.

Professional suspension builders, weekend track enthusiasts, and street tuners will find this kit beneficial when working with bolt-on or adjustable coilover platforms that accept 14mm collars. The two-pack format provides flexibility to experiment across multiple shocks or keep a backup set for track day adjustments.
