LEADING FUNCTION AND MECHANISM Point.1　NON PRELOAD VALVE

The leaf valve of CR damper piston does not need preload to stick each other.
This non preload valve can improve the oil flow and make the damping force earlier than conventional products.
It solves the rugged feeling on street.

Point.2　Barrel form spring

The barrel form spring is used for strut type front suspension that realize softness in low speed range and stiffness in high speed range by making the difference of spring inside diameter.

Point.3　Double seat ring

"This is our measument against for strut noise when turning the steering.
Pleastic seat reduces the sound and stainless seat smoothes the spring turning."

Point.4　Special chrome coating and aluminum material

"Special chrome coating is on thread part as it cannot be painted.
For lower seat and lock seat, the corrosion‐proof material (A6061) is used."

Point.5　Special design for each car model

"All of CR is designed for each vehicle even ride height, spring rate, damping force bracket shape and so on.
It works for smooth installation and best quality and performance."

Point.6 Durability test

"Test standard
Oil/Guss leak : less than 1/100mm
Oil seal durability : 1,000,000 times stroke (100,000km drive)"

Point.7 Testing run

All of CR trial samples are installed on the car actually and tested the riding comfortability, steering-feeling, stability etc.
