Land Rover Defender/RRP38 Ashcroft HD Crown & Pinion



Heavy-duty 4.10 ratio using a tooth count of 41 on the crown wheel and 10 teeth on the pinion.

Rear short pinion

  • Defender - 7A onwards

  • Range Rover P38


With the standard diff design, under extreme conditions, the front diff tries to climb out of full engagement under full power and then easily strips the teeth. 

Ashcroft has cut the gears in reverse for the front so they try to push together in mesh rather than push out so much stronger then the original design. Ashcroft looked at the materials used and compared these to the genuine materials used by Land Rover. The new range are now made from improved materials which is an improvement over the genuine specification.

All pinions accept the later 24 spline drive flanges and have the female thread to accept the later type bolt (FS112301P) and washer (FTC5413), all ring gear threads are the stock 3/8 UNF, we stock the late flanges head high tensile bolts for these also FTC5150, see related parts.

Ashcroft have chosen to coat the crown wheel and pinions in chemical black to aid corrosion resistance and offer a unique appearance.
