ASHCROFT DISCOVERY II HEAVY DUTY HALF SHAFTS AND CV KIT

Heavy Duty front halfshafts and CV joints to fit the Discovery 2.

As the D2 has a “open knuckle” type front axle we are able to put in a much larger diameter CV joint, this increased diameter not only allows a much thicker wall of the CV bell but also allows the use of bigger balls which reduce stresses and also allows us to increase the halfshaft from the small stock 32 spline to the much larger 24 spline, same as the 24 spline at the diff end.

Ashcroft have used the same proven materials in other shafts and CV”s, ie 4340 for the shaft and CV outer and 300M for the cage and inner.

Note when fitting these shafts you will have to swap the dust covers off the old shafts and refit to the new shafts with loctite.

From testing on Ashcrofts hydraulic test rig, the stock CV”s fail at 3700 ft/lbs, when testing the heavy duty ones the shaft failed before the CV at 7460 ft/lbs, over twice as strong.
