Skunk2's Drag Launch Adjustable Sleeve Coilovers for the '88 - '00 Civic and CRX, 93 - 97 del Sol, and 90 - 01 Integra are the industry's most affordable suspension system specifically designed for drag racing. Carefully chosen spring rates help distribute weight more optimally when launching for improved sixty - foots and quarter - mile times. 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.
