RETROARMS CNC piston for DSG 9T made of Nylon GF30

A specially extended, reinforced and significantly lightened piston designed for DSG assemblies. The piston can be used in standard gearboxes, but is optimized for RetroArms DSG gearboxes. This piston differs from the standard piston in that it has a longer body and at the same time adjusted dimensions of the guide rails ensuring less leverage during a short stroke of the piston. This piston has a precise surface at the top for the ball bearings integrated in RetroArms DSG gearboxes.

The rear part is significantly reinforced to withstand the forces created by the use of strong springs in TSG, DSG and SS assemblies in combination with rapid load changes due to high cadences. 

The Nylon material used is resistant to oils and despite the fact that it is not absolutely necessary to lubricate the guide grooves of the piston body, some lubrication pockets are integrated at the point of contact between the piston and the gearbox. The piston rack is made of high quality spring steel by CNC milling. The material used is flexible, and at the same time, thanks to the heat treatment, it is also hard, resistant to wear and tear.

This extended piston can also be used in combination with the extended DSG/TSG spring guide, which prevents the spring from twisting and there is teeth piston no risk of breaking the front part of the piston.
