Fits Yerf-dogs with 5 - 6.5 HP engines that use Max-Torque torque converters.  This is NOT the belt for Yerf-dogs with Comet torque converters.  The two belts are very different.

This is the original Max-Torque MXT97L belt, not an after-market.

Also used on some early Brister's Thunder Karts, but those should be replaced with the 20671 (not applicable to Yerf-dog).
