Pistons Forged Wossner and H-Beam Steel Rods - C20LET Turbo Set of 4

4 x pistons, 4 x piston ring set, 4 x gudgeon pins with circlips, 4 x steel rods, 1 x ARP rod bolt set

Wossner Forged Piston and H-Beam Steel Rod Package. 

The pistons feature a unique Moly coating on the skirts which allows the builder to run a much closer piston to bore tolerance than might be required on other piston makes. This helps remove the slapping noise during cold start, common place among engines running forged pistons due to larger then OE bore clearances.

The piston crowns are mirror polished to better resist detonation on a high performance engine. Mirror polishing allows a more even spread of heat inside the chamber which will help prevent “hot spots” on piston crowns.

No need to purchase extras, this package allows you to fit Forged pistons seamlessly.

Compression Ratio - 8.5:1

Bore Sizes: 86mm, 86.5mm, 87.0mm

Uprated H-Beam Steel Rods complete with uprated rod bolts.

H-Beam Con Rods are stiffer and more ridged which makes them better suited to high power/higher torque engines for example high power turbo builds. Our lightweight, H-beam section connecting rods are forged from 4340 high tensile steel. Heat treated and fully shot-peened for higher fatigue strength. Small end bushed for fully floating pin and big end fitted with high quality ARP fasteners.

Available for C20LET

Important Note:
For any engine rebuild we recommend and use oversize pistons (86.5mm) which require a mild rebore and hone to ensure correct piston to bore clearance to allow the pistons and bores bed in correctly.

Using standard sized pistons (86mm) in bores that have already been subject to wear (i.e. use) or bores that have not been machined to the specified clearances of the pistons, will lead to pistons and bores not bedding in properly and an engine that may be subject to high oil consumption.

Standard sized pistons recommended for use in Brand new engines only.
