89T Diff Spur Gear - CAT XLS

The Schumacher SCH-U7178 is an 89-tooth differential spur gear for the CAT XLS, suitable as a like-for-like replacement during routine maintenance or restoration. It helps maintain smooth, consistent drivetrain operation on vintage Schumacher RC buggies, supporting original gearing and preserving the handling character of the CAT XLS platform.

If your existing spur shows wear or chipped teeth, a fresh 89T spur can restore a clean mesh and reduce excess noise, helping protect other transmission components. Referencing the SCH-U7178 part number makes it straightforward to select the correct spare when servicing your model.
