Get Power Back To The Rear Wheels With A Part From Ram's Own Parts Brand

When something goes wrong in the rear differential, you find out quickly. Noise or leaks from the rear axle can park a working truck. The Mopar 68721135AA is a rear axle differential for the 2025-2026 RAM 3500. Mopar is Ram's own parts brand, so this part comes from the same name that supplies your truck's factory components. The differential splits engine power between the rear wheels and lets them turn at different speeds in a corner. On a 3500 that tows and hauls, it carries a lot of that work. This part is listed specifically for the 2025-2026 RAM 3500. Matching it to your truck is the first step, and Mopar's fitment lookup is the best way to do it.

Listed For The Ram 3500 Only With The Axle Details Left To Confirm

The Mopar 68721135AA 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 torque between the two axle shafts and lets each wheel turn at its own speed through a corner. Mopar does not list the gear ratio, spline count, axle size, or whether this unit is an open or locking design. Mopar's store shows this part as not fitting a 2025 RAM 2500, so it is listed for the RAM 3500 only. RAM 3500 trucks come in several axle and wheel configurations, so the right match depends on how your truck is built. Check your axle, wheel setup, and gearing against Mopar's fitment data before ordering.
