This Mace Torque-Lock limited slip differential (LSD) uses a sophisticated design to provide a quiet, automatic splitting of torque. It performs like an open differential under normal driving conditions, automatically transferring torque to the wheel with better traction when ground conditions warrant.

The advantage of the limited-slip differential design is apparent when comparing it to the standard or "open" diff. In vehicles with this older style ofdiff when one wheel began to slip or lose contact with the ground the slipping or non-contacting wheel would still receive the majority of the power whilst the contacting wheel remains stationary with the ground.

This issue is completely resolved with the Torque-Lock LSD. Harnessing a similar configuration to the Harrop and Eaton Truetracs, the automatic torque biasing design makes it the perfect limited slip differential upgrade for any enthusiast that will be using their vehicle for either straight-line drag, circuit, off-road or tough street work.

The proven helical gear technology found in the Torque-Lock LSD eliminates the need for wearable parts, resulting in maintenance free traction recognized not only for its durability, but its smooth and quiet operation as well. The low cost and effective operation all make the Mace limited slip differential the ideal choice for performance vehicles.

Fresh Spark Plug for the Mowing Season
Just what my push mower needed! Very compatible with my Craftsman M220 push mower. It was the right replacement part and workings just like the original brand B&S plug. Gap was correct right out of the box as my push mower fired right up first pull. Would recommend for anybody with a Craftsman M220.
