This is a complete 5 Ton Rockwell “Black Boot” Axle, pulled from late-model M939, M809, or M54 series military trucks. These axles are highly sought after in the off-road world thanks to their heavy-duty construction, top-load design, and iconic black CV boots that protect the steering knuckles.
The Black Boot variant is known for improved durability and factory upgrades over earlier 5 Ton Rockwell axles — including stronger axle shafts, better sealing, and reinforced housings. These axles are perfect for mega trucks, mud trucks, off-road builds, and military vehicle restorations.
Available in front (steering) and rear (non-steering) configurations. Whether you're planning a Rockwell axle swap, building a monster off-road rig, or restoring a military truck, the Black Boot 5 Ton axle is the top-tier choice.
