suspension adjustable coilover kit for VW Jetta

Piston Rod
The piston rod, larger in diameter to increase the strength, is hard-chrome plated, induction hardening , and fine polished for greater resistance to corrosion, thus, assuring of smooth action.

Oil Seal
The special Multi-slip oil seal, made of oil and wear-resistant high quality synthetic rubber, having high sealing efficiency to keep vital oil and gas in and dirt out of the cylinder.

Rod Guide
The sintered iron rod guide with a PTFE-bushed sliding surface, assures smooth rod action with minimal resistance and wear.

Nitrogen Gas
Nitrogen gas is filled in the reservoir except hydraulic type shock absorbers.

Rebound Stopper
A rebound stopper, made of a high quality synthetic rubber, or resin, is installed on the piston rod to act as the rebound stop.

Pressure Tube
The pressure tube, with a precision sliding surface mirror-like finish is designed to withstand tremendous internal working pressures, thus, providing greater reliability.

Piston Valve
Unique automatic control rebound disc valve, which automatically adjusts to all ride conditions, is designed to assure maximum performance and smooth ride control.It also provides instant response for full performance without any time lag.

Absorber Oil
Our absorber oil with constant viscosity, blended with chemical additives provide optimum operating performance keeping its efficiency, in any weather conditions.

Bottom Valve
Compression disc valve, which provides excellent performance, has automatic control actions similar to the rebound piston disc valve.
