Pistons Genuine Z20LEH 86.5mm and Forged Steel Rods - Z20LEx Turbo Set of 4

Genuine GM/Vauxhall/Opel Mahle Forged Z20LEH Piston Set and Forged Steel Rod Kit.

Four Oversize 86.5mm Z20LEH Pistons and Forged Steel Rod Set.

The Z20LEH pistons (as used in the Z20LEH Astra H VXR/OPC engines) are exceptional quality for a standard fit piston. They are made by Mahle of Germany and as well as being a forged piston they have the extra benefit of Teflon coated skirts for low noise. They are capable of withstanding engines producing up to 500bhp, providing correct fitting tolerances are observed and mapping is accurate.

Bore Size: for 2.0 Z20LEx engines - 86.5mm will require rebore and hone to correct tolerances.

Uprated Forged Steel Con Rods.

Forged Steel 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 8740 fasteners. Balanced to within 1g.

Available for Z20LEx (Z20LET, Z20LEL,Z20LER)

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

Package includes 4 x Oversize 86.5mm Z20LEH Genuine GM/Vauxhall/Opel Mahle Forged Pistons, piston ring sets and gudgeon pins, 4 x Uprated Forged Steel Rods complete with uprated rod bolts. No need to purchase extras, this package allows you to fit Forged pistons seamlessly.
