Dana 27 Axle Parts for Jeep CJ

The Dana 27 front axle, a step up from the earlier Dana 25, powered various Jeep models including CJ-5 (1960s-1970s), CJ-6, some CJ-3B, and military variants, featuring a 7.625-inch (7 5/8") ring gear diameter, 10-bolt differential cover, and commonly available ring and pinion ratios of 3.54:1, 3.73:1, 4.27:1 (most common stock), 4.88:1, and 5.38:1 for improved low-speed torque in off-road or steep terrain use. Known for its closed-knuckle design, drum brakes, narrow width, and solid but limited strength compared to later Dana 30/44 axles, the Dana 27 is popular among vintage Jeep restorers and flat-fender builders—upgrades typically include fresh bearings and seals for rebuilds, stronger aftermarket axle shafts to handle modern tires, regearing for tire size changes (though ratio options are somewhat limited), or adding traction devices for better grip without major swaps. Browse a wide variety of high-quality Dana 27 axle components, including precision bearings, heavy-duty shafts, ring and pinion gear sets in available ratios, traction devices like lockers, and overhaul kits, to help you restore, strengthen, or customize your classic Jeep for dependable trail performance and longevity.
