Description


Polini offers a reinforced primary kit for the Smallframe engines. This kit uses reinforced shock absorber springs that can cope with the high torque of a revised engine. These springs, unlike original springs, no longer go on block. This means that the springs are not completely compressed but still have sufficient travel. This means that load peaks are no longer introduced into the transmission and the components are protected despite higher engine performance. The primary kit is delivered ready to install and has reinforced cover plates for the primary springs.

An optimal supplement to adapt the engine to another race track or modified components are the additionally available primary pinions. This allows the reduction ratio of the existing primary kit to be lengthened or shortened in a wide range.
