6.7 Powerstroke Axle and Differential

Heavy-Duty 6.7 Powerstroke Axles, Differentials & Gear Upgrades

Transferring the massive torque of a 6.7L Ford Powerstroke engine to the ground requires an incredibly robust unsprung drivetrain. Whether your truck is utilizing a front Dana 60, a rear Sterling 10.5, or a heavy-duty Dana M275/M300 assembly, the internal components of your axles and differentials face immense stress. Under the strain of heavy fifth-wheel towing, hot shotting, or high-horsepower street launches, factory open differentials can leave you spinning a single tire, while stock ring and pinion gears can experience premature wear or chipped teeth. Upgrading your 6.7 Powerstroke axles and differentials ensures that your truck maintains maximum traction, structural integrity, and reliability on any terrain.

Our comprehensive selection features premium drivetrain upgrades and replacement components engineered specifically for the 6.7L platform. We stock high-strength replacement axle shafts, rugged ring and pinion gear sets in various ratios to correct speedometer and RPM ranges after installing larger tires, and performance traction add-ons. From selectable air and electronic lockers to automatic limited-slip differentials like the Detroit Truetrac, these upgrades provide true dual-wheel power delivery when pulling heavy loads through mud, snow, or loose gravel.

Beyond internal gears and carriers, managing the fluid health inside your axle housing is critical to long-term dependability. Upgrading to a heavy-duty, cast-aluminum differential cover adds extra fluid capacity to lower gear operating temperatures, incorporates cooling fins to shed heat rapidly, and reinforces the housing against structural deflection under maximum load. Most performance covers also feature magnetic drain plugs to catch loose metallic debris before it can damage your bearings.
