C/O Slotted Top Koni

The C/O Slotted Top Koni coil-over spring seat is a precision-engineered suspension component designed for vehicles equipped with Koni shock absorbers. This aluminum spring seat accommodates 2.5-inch ID springs and features a drilled construction that reduces unsprung weight while maintaining structural integrity. Black anodized finish provides corrosion resistance and a professional appearance suitable for both street and performance applications.

The slotted top design allows precise ride height adjustment by enabling multiple mounting positions, a critical feature for tuners optimizing suspension geometry. The 2.5-inch spring ID matches common coilover spring specifications found in aftermarket performance suspension systems. Aluminum construction delivers a lightweight solution compared to steel alternatives, directly reducing sprung mass and improving responsiveness. Black anodized treatment resists oxidation and maintains appearance through repeated exposure to moisture, road salt, and UV conditions.

This component serves builders and enthusiasts working with Koni shock systems on road course vehicles, daily drivers running lowered suspension, and off-road rigs requiring adjustable spring rates. The compatibility with Koni hardware makes it an essential piece for anyone replacing or upgrading existing coilover setups. Individual sale (one per order) accommodates both single-shock replacements and customers building complete front or rear axle assemblies incrementally.

Suspension tuning demands precision at every level—spring seat geometry directly influences how load transfers through the shock and into the chassis. OEM and aftermarket builders standardize on the 2.5-inch ID specification to ensure compatibility across widely available spring options. Slotted adjustment capability separates this product from fixed-position alternatives, providing flexibility for mid-build modifications without component replacement.
