HKS Hipermax S Coilover Kit – Nissan 300ZX (Z32)

Upgrade your vehicle's suspension with the HKS Hipermax S Coilover Kit (part number 80300-AN019), designed to replace the factory shocks and springs on your Nissan 300ZX Z32. Engineered to balance handling stability, reduced body roll, and daily street-driving comfort, this kit features a single-tube (monotube) upright damper layout for both the front and rear axles.

At the core of the Hipermax S is a Dual Preload Valve System (PVS) which improves response and smooths out harsh road vibrations, paired with a Wide Range (WR) needle that offers 30 distinct levels of manual damping force adjustment. The shock bodies are protected with HKS's signature PNE coating to deliver superior corrosion resistance, while heavy-duty rubber upper mounts control deflection. Full-length ride height adjustment is handled independently via the lower brackets, ensuring you can lower the vehicle without compromising shock stroke or changing spring preload.
