Similar to Skunk2's industry - leading Pro - C Coilovers, Pro - S II Coilovers for the 02 - 04 RSX 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.
