Ashcroft Heavy Duty Shaft Set - Rear - Discovery 2

There shafts are made from '4340' alloy steel. They have also made some design improvements to remove the stress concentration which typically causes failure at the diff end, this allows the shaft to flex along its length absorbing much of the shock loads.

Ashcroft designed and built the testrig mentioned above to allow them to twist shafts until they failed to get a definitive measure of the elasticity and ultimate strength. The rig consists of a steel box section frame which holds a 3000 PSI hydraulic power pack, pressure gauge, 100mm diameter ram, 75mm duplex chain and a large diameter sprocket. This sprocket is bolted to a drive flange and another drive flange is bolted to the frame, the shaft is fitted between the 2 drive flanges and when a valve is opened the ram pulls the chain which in turn twists the shaft.

All Ashcroft HD shafts have a 5 year warranty against failure.

Supplied as a pair.
