Keep the massive torque of your First-Generation truck securely planted with our premium selection of 1989-1993 Dodge 5.9L 12V Cummins axles and components. While the legendary 12V engine block is built to run forever, decades of heavy towing, high-mileage wear, or increased tire sizes put immense stress on your classic rig's factory drivetrain. Maintaining and upgrading your front and rear differentials ensures smooth power delivery and eliminates catastrophic failures on or off the road.
At Norcal Diesel Performance, we offer a rugged catalog of driveline parts engineered specifically for the iconic Dana 60 front and Dana 70/70U rear axle setups found on classic D250 and W250 platforms. Eliminate whining and restore factory tolerances with high-quality ring and pinion gear sets, chromoly high-strength replacement axle shafts, and complete master overhaul installation kits packed with premium bearings and seals. We also carry high-capacity, finned aluminum differential covers that maximize fluid capacity and keep your gear oil cool during grueling hauls.
Whether you are rebuilding an original Dana axle back to OEM specification, adding a traction-locking differential for off-road performance, or upgrading universal joints, we provide the specialized components your truck requires.
