The 5 Ton Rockwell Zipper Boot is a quick-install split CV boot designed to protect the steering knuckles on front Rockwell 5 Ton axles. Commonly found on M939, M809, and M54 military trucks, these boots are a game-changer for anyone running Rockwells in a mud truck, off-road rig, or military restoration.
Unlike traditional boots that require full knuckle disassembly, this zippered version wraps around the knuckle and seals securely — allowing you to replace damaged boots in the field or shop without pulling shafts. It keeps your knuckles clean and sealed, protecting against mud, water, and trail abuse.
Built to last, this is a must-have upgrade or replacement for anyone using Rockwell 5 Ton front axles in extreme conditions. Keep your axle protected and maintenance simple with this rugged, no-hassle zipper boot.
