C/O Spring Seat - Slotted Clear Anodized

The C/O Spring Seat - Slotted Clear Anodized (QA1 9018-102) is a precision coil-over spring seat designed for custom suspension builders, fabricators, and enthusiasts who demand reliable component control in aftermarket coil-over systems. This universal slotted spring seat accommodates 2.5-inch inner diameter springs, making it an essential upgrade for independent suspension tuning, track racing applications, and street-performance builds where spring alignment and load distribution are critical to ride quality and handling consistency.

Manufactured from aluminum and finished in clear anodize, this spring seat combines corrosion resistance with a clean, professional appearance that resists oxidation in both wet and dry environments. The slotted design permits fine-tuning of spring preload and height adjustment without complete disassembly, reducing installation time and allowing for on-track or garage tuning. The 2.5-inch ID specification ensures proper seating of common coil-over spring diameters, while the universal fitment means integration into various suspension geometries and platforms. Clear anodizing preserves the natural aluminum finish while providing a protective oxide layer that maintains durability through repeated adjustment cycles.

Performance suspension shops, chassis builders, and DIY enthusiasts benefit most from this component when constructing or upgrading double-adjustable or triple-adjustable coil-over systems. The lightweight design—just 0.23 pounds—minimizes unsprung weight while the compact 4.2 x 1.75 x 4.95-inch footprint fits seamlessly into tight suspension bays. Individual sale allows buyers to purchase the exact quantity needed for their project, whether upgrading a single corner or replacing worn seats across all four suspension points.
