40Cr STEEL SPIRAL-CUT 37-TOOTH RING AND 13-TOOTH PINION DIFFERENTIAL GEAR SETS

Description

The GPM SLA1337RS is a precision-oriented 40CR steel spiral-cut differential gear set designed to improve meshing consistency in the TRAXXAS Slash 4X4 rear gearbox. The kit includes a 37-tooth ring and a 13-tooth pinion made from 40CR steel; the spiral tooth profile promotes smoother engagement and more even load distribution across the contact area, which helps reduce shock loading and supports predictable torque delivery under demanding conditions.
