Industry Insider: Tein’s Shock Service


The fluid is carefully poured into the assembled shock body.
The piston rod assembly is carefully lowered into the fluid.
The seal retainer is screwed down and torqued to the proper tightness, sealing up the shock.
The shock is then pressurized with nitrogen gas using this device which injects it under the seal. The nitrogen pressurizes the oil and reduces foaming and cavitation in the valve pack for more consistent damping during hard use.
The freshly revalved shock is then run on the shock dyno to make sure everything was assembled correctly.  The dyno measures hydraulic force over velocity.   If something is wrong it will become immediately apparent.  Our shocks passed with flying colors.
The rest of the coilover components for our shocks receive a thorough cleaning and inspection.
