With the Hipermax III suspension series, the driver gains increased wheel control with improved performance of all vehicle dynamics and increased driver command in all conditions.

Hipermax III combines track-quality control with excellent ride and handling characteristics at real-world street speeds. HKS' all-new Hiper Linear Piston Fluid Channel System damping system creates a positive relationship between piston speed and damping force, making it possible to produce a suspension that provides track-level control and feedback with exceptional ride quality at the same time.

In addition, the Hipermax III is shock-body adjustable to allow vehicle height adjustment without affecting spring rate and piston stroke.

Key Features:
• Hiper Linear Piston – Linear progression piston adjusts oil passages for precise stroke management resulting in smoother valve movements. As piston speed increases, dampening rate linearly increases.
• Strengthened rubber upper mounts – enhanced durability
• Monotube design
• Shock-body length adjustable (most applications)
• 65mm diameter springs – Cold wound and manufactured in-house at HKS to ensure quality and consistency
• Stainless lock nut & ride height adjuster – feature anti-rust & corrosion characteristics for enhanced durability.
• 30-way adjustable dampening
• Hard chrome-plated cylinder shaft
• Non-electrolysis Nickel plated shock bodies provide durability in severe weather conditions.
• Pillowball upper mounts optional on certain applications
• Dustboots standard
• 1 year limited warranty

Fits: Subaru WRX STi 2005-2007
