Protlum Race - Yugo

Shock absorbers with external reservoir without damping adjustments

Doubletube gas-liquid dampers RACE class are intended for racing use and developed for very hard conditions. These dampers are equipped by external reservoir for separation of oil and nitrogen content. 

Advantage of this solution avoiding of foaming of oil during drive, resulting into the change of damping characteristics and degradation of damping performance. Negligible advantage is bigger content of oil, ensuring better distribution of heat on the whole damper surface.

Shock absorbers of RACE class are supplied with optimal setting for each vehicle, but customer has a possibility of slight tuning by change of internal pressure in external reservoir.

Properties of RACE shock absorbers:

• external reservoir with possibility of gas pressure change

  adjustable car height

• progressive springs (linear optionally)

• axial bearing on struts/McPherson units

• steels parts made from highstrength CrMo steel

• alu parts made from highstrength dural
