These H section steel con rods are stronger than standard rods, plus give a massive weight saving and use ARP2000 bolts made from EN24V material and shot-peened, which gives added strength to the con rod.
Using fully floating small ends, these con rods can only be used with pistons that use circlip grooves as per our part number COM224.
The big ends are a different size to the standard Healey to benefit from modern bearings COM246R so they can only to be used with our steel crankshafts COM237 & COM238.
MUST USE STEEL CRANK
