HKS HiperMAX IV GT - Although this is a product designed for comfort and stylish appearance it is able to hold its own with regards to road performance. We recommend this product to people who would use this vehicle daily and want as much comfort as possible for themselves and their passengers and those who want to reduce arch gap or lower their car.

HKS has developed the MAX IV according to thorough data analysis of many cars in the market and tested them all. They didn't only increase the rate of damping but also analyzed balance and stroke, which made this product more safe and fun to drive. HKS also redesigned the inner parts and developed new parts for MAX IV. MAX IV has new design of needle which gives more stable damping and steering characteristic at a low to mid speed range. We also revised dial adjustment by oil path and this new design makes even under 10 step dial, it will not be too stiff. 

Single Tube Damper Design

Mono tube dampers allow for more accurate and stable control and adjustment of dampening. Lower ride height and center of gravity gives a more stable ride.

Dustboots Standard

Shaft damage by rocks and pebbles from bouncing onto the shaft can be prevented.

PNE Coating

Using this special surface coating provides 5 times better durability over standard galvanizing. This prevents buildup around the threads of the adjustment areas allowing for easier adjustment.

M Shaft (46 Normal Type)

Hipermax M1 "M Shaft" which was created to pursue "suppleness" has been used to optimise internal oil pressure properties. producing proper dampening even with the smallest strokes, a supple yet stable ride is possible.

New Design Needle

Newly designed needle has been used to revise the low speed dampening which is key to ride comfort.

Reduction of Unsprung Weight

In order to reduce unsprung weight, rear bracket, ride height adjusters and lock nuts are made from aluminium. (front bracket is made from steel for strength)

30 Step Dampening Force Adjustment

30 levels of dampening adjustment allow fine tune adjustment for street or circuit.
