PEC Steel Con-Rods with Wossner Forged Pistons




PEC Steel con rods- H-Beam  connecting rods are forged from AISI 4340 (En24) steel. Heat treated to HRC 35-38 and then shot peened for a higher fatigue strength. Small ends are bushed for a fully floating pin and big ends are fitted with high quality ARP fasteners with different specification bolts available depending on the level of performance required.



Wossner are regarded by Europes leading motor sport engine builders as being the piston of choice when building an engine not only to perform, but to withstand the stresses and duress's of competition life, Wossner pistons feature a unique PTFE coating on the skirts and grade of 4032 alloy t6 which allows the engine builder to run a closer piston to bore tolerance then he might do another piston. This helps remove the slapping noise during cold start, common place among engines running forged pistons due to larger then OE bore clearances. The crowns of the pistons are also polished to better resist detonation on a high performance engine. Polished allows a more even spread of heat inside the chamber which will help prevent hot spots on piston crowns. Includes all piston rings and gudgeon pins.
