HIPERMAX R specification

■ HIPERMAX R Special Equipment

HIPERMAX R Exclusive newly developed oil "SRF (Super Response Fluid)"

Special high-viscosity oil that is resistant to heat sagging has been developed. Damping starts up from a very low speed range, resulting in reliable handling, great damping and high stability.

HIPERMAX R Exclusive High-Strength Spring "LVS(Low Vibration Spring)"

Newly developed special spring for high-strength wire that is ideal for sports driving. Provides excellent response and smooth ride.

Spring Retainer

Retainer on top of spring is standard equipment. This eliminates side forces and lowers friction. Stability is improved by following changes in load.

■ HIPERMAX R Core Technology

Dual PVS: Dual Preload Valve System

Features the Dual Preload Valve System originally designed for the HIPERMAX S. By carefully selecting valve shims for each vehicle model, the settings are tailored to the vehicle to provide direct handling and reliable stability.

WR Needle: Wide range damping force adjustment mechanism

The improved shape of the needle expands the oil relief channel. Each step of the 30 steps adjustment is now more prominent. Having softer adjustment options gives more options for street driving.


The advanced bump rubber newly featured for HIPERMAX S is utilized.
The shape aims for an early bump touch, gradually damping the load and suppressing abrupt changes in movement.

Single Tube System

The Mono-Tube design of the HIPERMAX series is adopted. The structure allows the gas and oil chambers to be separated, and the use of a large-diameter piston provides high quality and stable damping force characteristics.


Inverted Type Damper for Strut Type

Firm rigidity against stress has been achieved. It works to the advantage of various performances when driving, and provides excellent handling and ride comfort.

PNE Coating

Prevents sticking due to rust, which is the bottleneck of full-length adjustable dampers. Also, the smooth surface reduces the force required for vehicle height adjustment.

Pillow Upper Mount

The genuine rubber upper eliminates unnecessary movement, making more precise and sharper handling.

"KODAWARI" of Exterior: Chamfered Upper Mounts

The aluminum upper mount has been chamfered by machining to evolve the beauty of the product. The machining process was increased to improve the feel and appearance of the product.

"KODAWARI" of Exterior: Laser Marking

The logo expresses a sense of luxury through the delicate characters created by laser marking, which cannot be expressed by pad printing.
