Skunk2 Racing [88-91 Civic/CRX] Pro-S II Coilover Set - 10K/8K Spring Rates

Similar to Skunk2's industry-leading Pro-C Coilovers, Pro-S II Coilovers for the 88-91 Civic and CRX 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.

Upgrade the suspension performance of your 1988-1991 Honda Civic or CRX with the Skunk2 Racing Pro-S II Coilover Set, part number SKK541-05-4715. Designed for both street and track use, this set combines adjustable ride height, vehicle-specific shock valving, and a race-inspired monotube construction to improve handling, responsiveness, and overall vehicle balance.

• Ride-height adjustable with independent spring preload
• Fixed damping with front and rear 10K/8K spring rates

The Pro-S II Coilovers use fully threaded, shortened shock bodies that allow ride-height changes without sacrificing shock travel or ride comfort. The reduced shaft stroke helps maintain useful suspension travel on lowered vehicles, while the adjustable design supports corner balancing and precise chassis setup. Ride height can be lowered by as much as approximately 3 inches for a more aggressive stance while retaining functional suspension performance.

Each shock features vehicle-specific valving developed by Skunk2 suspension engineers, along with custom-matched racing springs manufactured from SAE9254V spring steel. The micro-polished monotube design, one-piece forged shock bodies, oversized precision-machined shafts and pistons, and super-finished hard chrome shafts are engineered for responsive operation and long-term durability. Polyurethane bushings help improve shock feedback, while billet top hats and hard-anodized, CNC-machined forged 6061-T6 aluminum spring perches provide a precise and durable foundation for adjustment.

This four-piece Pro-S II set includes front and rear coilovers with fixed damping, adjustable ride height, independent spring preload, and 10K/8K spring rates. It is intended for 1988-1991 Honda Civic and CRX applications and is suited to drivers seeking improved cornering grip, reduced body roll, and more controlled handling without giving up everyday usability.
