The low-speed adjusters use a special designed bore of which the area can be varied. The adjuster is located on top of the remote reservoir and has eight adjustment positions. Changes made to low-speed damping forces (shock rod velocity of less than 2 inches per second) have a major effect on handling because corner entry, corner exit, braking, and power down are all about low speed shock rod movements.


In the current shockprogram, ProTrac damper technology developed complete sets for several Circle Track Cars. These extremely succesfull sets are available in single, double or triple adjustable configuration.

ProTrac is capable in manufacturing every damper for Circle Track purposes. All build with exact characteristics and the highest quality material.

The triple adjustable dampers have separate adjustment devices to control the low speed compression damping forces without effecting the mid- and high-speed range. Because the large 22mm piston rod provides sufficient oil flow on very small low-speed damper movements, the low-speed adjuster mechanism is very sensitive and responsive.

Pavement Modified Series


These complete sets are the way to go to fine tune your Circle Track Race Car.
