Product Description
This axle is new in crate in Macon, GA. It includes all that is pictured.
This is a complete axle assembly (drive axle with differential, suspension arms, and brake components) used on tactical wheeled vehicles. The 3680 lb weight and packaging point to it being a Meritor ProTec™ series independent suspension axle, developed for heavy armored trucks.
Military Vehicle Applications
Besides MRAPs, this axle is known to be fitted on:
• M-ATV (Oshkosh M-ATV MRAP variant)
• Some FMTV A1P2 armored variants
• Certain JLTV prototypes (Oshkosh JLTV used Meritor ProTec independent axles early on)
• It may also appear in Buffalo and Cougar MRAP sub-variants depending on configuration.
It is essentially a heavy-duty independent suspension drive axle designed for armored 4x4 and 6x6 tactical vehicles.
Manufactured by Oshkosh. Axle is absolutely beautiful. Mrap Axle.
From Frame Rail to Frame Rail they measure 4 Ft or 48 in. Perfect for all of those great projects! All axles are securely packaged in a wooden crate.

Fitment:
• Oshkosh TAK-4® Family brochure — platform list + performance specs (wheel travel up to 16–20 in, ground clearance figures, GAWR bands for light/medium/heavy). Vehicles shown using TAK-4 include MTVR, LVSR, M-ATV, RG-31A3, RG-33, Cougar (MRAP family), PLS A1, and L-ATV (JLTV).
• Meritor (now Cummins) ProTec ISAS sheet – 3000 Series — comparable independent axle specs (front up to 12,000 lb, rear up to 15,400 lb, up to 33.5° steer, CTIS-ready, geared hubs, etc.). Useful for spec comparison to other MRAP-class axles.
• ProTec overview page (Cummins) and defense catalogs for additional context on independent suspension axle systems.
Fitment notes
• Oshkosh TAK-4 IDS front steer module used across multiple Oshkosh-built tactical trucks (not just “MRAP” generically). The TAK-4 brochure shows the specific families above; MTVR is the closest direct match (your label also aligns with MTVR/LVSR service kit lines in the Oshkosh parts list).
