This GPM Delrin main gear, DNMT2053T, is specified as a 53 tooth replacement for HPI Nitro MT2 applications where reduced friction and extended wear resistance are required. Delrin offers a low friction contact surface that helps stabilise gear mesh and limit abrasive wear on plastic pinions and spur sets. Fitment is direct and intended as a straightforward drivetrain upgrade for hobbyists seeking consistent engagement and longer maintenance intervals.
