Ashcroft P38/Wolfe Locker
This model is to suit the P38 Range Rover and the 2002 onwards 110 rear axle.
Ashcroft wanted a selectable locker which would fit into the rover diff casing with minimal installation work, ie without mods to the axle housing. We looked at electric and pneumatic activation and decided pneumatic was preferable for reliability and simplicity. One of the key requirements for our design was zero air leaks as this is one of the main issues with other air operated lockers. To achieve this we opted for a static piston rather than the rotating seal used on other air lockers, which was prone to leaks. We also wanted to ensure we had a full 6mm of engagement when locked as other air lockers have just 2.5mm and are prone to skipping out of lock when loaded
