Skunk2’s Adjustable Sleeve Coilovers 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-inch drop (sometimes more).
