HKS 80330-AH001 Hipermax S Coilover Suspension Kit

The HKS Hipermax S (80330-AH001) is a premium monotube coilover suspension kit engineered by HKS, one of Japan's most respected performance tuning brands. Designed for enthusiasts seeking an ideal balance between daily drivability and spirited performance, the Hipermax S delivers a refined, adjustable suspension solution built to HKS's exacting standards.

Key Features:

• Single-Tube (Monotube) Design: Provides more consistent damping performance and improved heat dissipation compared to twin-tube designs
• Ride Height Adjustment: Full coilover design allows ride height to be adjusted independently of spring preload for a proper, dialed-in stance
• Street-Tuned Damping: Factory-set damping valving optimized for real-world street use while retaining sporty handling characteristics
• High-Quality Springs: HKS-spec linear-rate springs matched to the damper valving for predictable, progressive handling response
• Pillow Ball Upper Mounts: Included on select applications to improve steering response and handling precision
• Rust-Resistant Construction: Corrosion-resistant materials and finish help ensure long service life
• Direct OEM Replacement Fitment: Bolt-on installation with no modifications required on supported applications

The Hipermax S series sits within HKS's performance street lineup, offering a significant upgrade over factory suspension for drivers who want improved body control, reduced dive and squat under braking and acceleration, and a more engaging driving experience — without sacrificing everyday comfort. As with all HKS suspension products, the Hipermax S is developed and validated on Japanese test courses and real-world roads.
