The Rear Axle Part You Never Think About Until You Need It

Your rear differential does a job you never notice until something goes wrong. It sends engine power to the rear wheels and lets them turn at different speeds through a corner. On a RAM 3500 that tows and hauls, it works hard every day. When one needs replacing, you want a part made for your truck. The Mopar 68721221AA is a genuine Mopar rear axle differential for 2025-2026 Ram 3500 trucks. Mopar is Ram's own parts brand, so you are buying from the same name that supplies your factory parts. This part number is new for the 2025-2026 model years, so confirm your axle setup before you order.

What Mopar Lists For This Rear Differential And What To Confirm Before You Order

The Mopar 68721221AA is a rear axle differential for 2025-2026 RAM 3500 trucks. Mopar lists its position as rear and its other name as differential. A differential splits engine torque between the two wheels on an axle and lets them rotate at different speeds in a turn. Mopar does not list the gear ratio, spline count, or whether this unit is an open or locking design. Ram 3500 trucks come in several rear axle and wheel configurations, so those details matter. Check your truck's axle size, wheel setup, and gearing against Mopar's fitment data before ordering.

Fitment: 2025, 2026 RAM 3500
