Similar to Skunk2's industry-leading Pro-C Coilovers, Pro-S II Coilovers for the 01-05 Civic feature adjustable ride height and a state-of-the-art mono-tube design. Thanks to threaded shock bodies, Pro-S II Coilovers offer height adjustments independent of spring preload, which results in significant ride-height changes without sacrificing shock travel or ride comfort. Quick and precise ride-height adjustments can be made for dialing in corner balancing as well as for improved handling, responsiveness, and overall balance. Skunk2's track- and street-tested Pro-S II shock valving offers the perfect balance between daily driving and track performance and its all-new, shortened shock bodies and reduced shaft strokes help maintain adequate suspension travel on lowered vehicles for improved performance without sacrificing comfort. Pro-S II Coilovers feature vehicle-specific valving dialed in by Skunk2's suspension engineers, carefully selected springs designed to dramatically improve handling, and a race-inspired, mono-tube design for superior performance. Skunk2's micro-polished, mono-tube design and one-piece, forged shock bodies, combined with its precision-machined, oversized shafts and pistons, ensure that each Pro-S II Coilover is both responsive and durable. The results are unmatched cornering grip, reduced body roll, and a feel of vehicle control and stability like no other. Pro-S II Coilovers feature hard-anodized, CNC-machined, forged 6061-T6 aluminum spring perches and CNC-wound racing springs manufactured from high-quality, SAE9254V spring steel. Each spring is designed to optimize the balance between comfort and performance and is custom-matched to their respective shocks. Pro-S II Coilovers offer ride-height adjustments as low as three inches for an aggressive and sporty appearance. Just like the entire Pro Series lineup, Pro-S II Coilovers set the benchmark for suspension performance.
