The GPM XRT033TS Carbon Steel Spur Gear is engineered for TRAXXAS XRT 8S drivetrains, using a 33T gear forged from 40Cr carbon steel to increase wear resistance over the original component. The three-point support arrangement improves mesh stability and helps maintain consistent power transfer. The kit includes a 7075 aluminum mount, bearing and cush drive input shaft to support reliable installation and service life.
