Since the standard connecting rods cannot withstand an increase in performance from 500 HP, we lead steel connecting rods.

From a boost pressure of 2 bar, TURBO piston pins must be changed. (see further below)

FSR pistons:
The asymmetrical FSR piston line (Forged Side Relief) by JE Pistons includes a modern forged design with a wider piston shirt on the main pressure side and a smaller, friction-reducing shirt on the side pressure side. In combination with precise CNC machining, a high-strength, lightweight piston is created that is extremely durable.

Ultra series:
The pistons of the Ultra series combine all premium functions from JE and the brand new technology of the forging industry!
The revolutionary Perfect Skirt coating from JE is one of the many technologically advanced aspects of the Ultra series. It protects the piston shafts, reduces friction and prevents cold start piston shocks and incorrect knocking.
All pistons in the Ultra series are supplied with a ceramic crown coating as standard to ensure a longer service life and better exhaust gas cleaning properties.
Thicker piston pins made of premium material are another feature of the Ultra series.
In combination with the special grain flow-optimized forging technology, the Ultra series is ready for enormous performance.
