About Us

Penske Racing Shocks UK - a division of GXC Engineering

We offer a comprehensive range of racing dampers for both 2 and 4 wheeled motorsports. Penske Racing Shocks have enjoyed championship winning success in a variety of motorsports from Formula One, to GT Racing, and the British Touring Car Championship.

Penske Racing Shocks are manufactured from the finest materials available for quality, simplicity, consistency and most importantly high performance. The shafts are machined from 4130 chromoly, whilst all aluminium parts are machined from 7075-T6 or 6061-T6 and are then hard anodised to prevent corrosion. 

Penske Racing Shocks develop the majority of their damping force at the piston – the forces achieved are determined by the piston and shim stack selection. Our piston and shim combinations allow an infinite range of damper graphs and styles to be achieved.

All Penske Racing Shocks are completely hand built to customer specification. No racing car/bike is exactly the same and we tailor the damper spec exactly to your requirements. 

Customer support is very important to Penske Racing Shocks UK – we offer extensive support when specifying your damper requirements and also when using your dampers – we like to win just as much as you do!

Penske Racing Shocks UK also offer the highest quality servicing/re-valving at our workshop facilities which includes a full diagnostic and development damper dynamometer test rig. We also offer test/trackside engineering accompanied by our fully equipped mobile workshop which includes damper dynamometer.
