Tuning your vehicle’s suspension is one of the easiest ways to instantly improve overall performance. The HKS Hipermax Damper II suspension, which offers both ride height and shock dampening adjustments, provides improved handling characteristics while maintaining your vehicle’s ride comfort. Ride height is adjusted by simply rotating the 60mm spring retainer perches around the chromed steel shock body. The dual interlocking spring retainer perches prevent spring movement and unwanted ride height changes. Dampening can be adjusted at 30 settings (20 on some applications) to deliver the desired shock compression and rebound stiffness for custom tailored driving characteristics. The included anodized aluminum upper Pillowball mounts retain spring placement and improve steering response and maintains suspension geometry. Additionally, some applications offer camber adjustments on the upper Pillowball mounts. Each HKS Hipermax Damper II suspension system comes with all the need adjustment wrenches, stiffness adjusting knobs, and miscellaneous hardware for a complete installation and tuning.Features:Chromed Steel shock body assembly with precision-cut threadsShortened cylinder body and piston strokeSingle tube structure with large free pistonSingle tube structure with low-pressure nitrogen gasDual oil and gas chambersAnodized aluminum Pillowball upper mountsAnodized aluminum spring perchesDual rate progressive coil springsFully rebuildable
