Improved Traction

Help both driven wheels contribute when one side loses grip on uneven ground.

Serious Off-Road Capability

A valuable upgrade for demanding green lanes, competition, work and expedition vehicles.

Axle-Specific Options

Products designed for particular axle types, differential centres and spline configurations.

Supporting Components

Related switches, airlines, compressors and installation parts where required.

Identify the exact axle and differential

Diff lockers are highly application-specific. Confirm axle type, spline count, differential, model and any existing drivetrain modifications before ordering.

Built for life outdoors

Choose specialist traction products from respected off-road manufacturers and established 4x4 brands.

Adventure tip: Professional fitting and correct setup are strongly recommended. Incorrect installation can damage the differential or axle.
