Skunk2's Adjustable Sleeve Coilovers for the '01-05 Civic Si are the industry's most affordable yet aggressive suspension system that allows street and track enthusiasts to fine tune vehicle ride height, balance, and handling performance. With nearly 15 years of spring technology and suspension tuning experience, Skunk2's race-inspired, Adjustable Sleeve Coilover system provides a cost-effective alternative to more expensive full coilovers like our Pro-S II and Pro-C systems. Each Adjustable Sleeve Coilover kit features hard anodized, CNC-machined aluminum sleeves, forged spring perches, SAE 9254V racing springs, and mounting hardware that allows for as low as a three- in. drop (sometimes more). Designed to be used with OEM or aftermarket shocks, Skunk2's Adjustable Sleeve Coilovers allow for independent shock replacement, which means suspension systems can be upgraded in stages. When applicable, Skunk2 Adjustable Sleeve Coilovers should be paired with Skunk2 Sport Shocks for maximum performance.
