Spartan Locker for Dana 30 differential with 27 spline axles includes heavy-duty cross pin shaft

The USA Standard (Yukon) Spartan Locker SL D30-27 is a mechanical locker designed for Dana 30 differentials equipped with 27-spline axles. It is a cost-effective solution for improving traction in off-road and slippery conditions. The Spartan Locker replaces the spider gears in your open differential, providing automatic lock-up when torque is applied, and unlocking when the torque is removed for smoother turning. This unit includes a heavy-duty cross pin shaft for increased durability. Installation is relatively straightforward for those with mechanical experience, as it does not require carrier removal or shims.
