Honda TRX420 Rancher Rear Brake Drum – 2007–2010 – OEM 43620‑HP5‑600 Replacement – OE‑Spec

OVERVIEW

This rear brake drum is engineered specifically to deliver consistent stopping power and safe deceleration for your ATV. Designed as a direct mechanical replacement, the one-piece cast-and-machined body provides a smooth friction surface that pairs reliably with standard brake shoes. It restores secure pedal contact while fitting precisely onto the Honda TRX420 Rancher platform.

ENGINEERING & PERFORMANCE

The precision-machined interior works in tandem with factory-style shoes to eliminate pedal pulsation and maintain predictable friction under repeated loads. This one-piece cast and machined construction resists thermal warping and distributes friction evenly across the drum face. Built to meet or exceed OEM dimensional tolerances, the hub slides directly into the existing backing plate for immediate installation without drilling or modification, ensuring uninterrupted riding control.
