The GPM 85T spur gear is manufactured from hardened steel #45 to deliver consistent wear resistance for the ELEMENT ENDURO SENDERO TRAIL TRUCK. This gear provides a modest reduction in tooth count from 87T to 85T, producing a higher final drive ratio while allowing the original motor pinion to remain fitted. The component is intended as a durable, drop-in upgrade for hobbyists focused on reliable speed gains with minimal drivetrain changes.
