Product Description

The HKS 80330-AN020 Hipermax S is a complete front and rear coilover kit purpose-built for the 1997-2001 Nissan Stagea AWD (WGNC34) equipped with either the RB25DET or RB26DETT inline-six engine. Built on HKS's monotube damper platform with Flat Ride Concept (FRC) and Dual Preload Valve System (Dual PVS) tuning, this kit is designed to lower the WGNC34's center of gravity and tighten body control without sacrificing the compliance needed for daily street use. The 30-step WR Needle damping adjustment allows the driver to dial in feel across a wide range of conditions - from relaxed highway cruising to spirited mountain-road driving. Front and rear spring rates of 98 N/mm and 88 N/mm respectively are set firm enough to control the Stagea's AWD chassis under load while remaining livable on imperfect road surfaces.

Ride height adjustment is preload-independent via the length-adjustable shock body, giving a front lowering range of up to -79 mm and rear of up to -52 mm from factory ride height. DURA BOOTS and Advanced Bump Rubber Plus contribute to long-term durability across a range of environmental conditions. This kit is compatible with AWD 4WD manual transmission models only (chassis E-WGNC34 and GF-WGNC34) and is not suitable for rear-wheel-drive Stagea variants. It supersedes part number 80300-AN020, ships via UPS or FedEx only, and is covered by HKS's 3-year / 60,000 km manufacturer warranty.
