Dana 25 Axle Parts for Willys Jeep CJ

The Dana 25 front axle, a rugged and reliable design from Dana Spicer, powered early Willys/Jeep models including the CJ-2A (1946-1949), CJ-3A (1949-1953), CJ-3B (1953-1968), early CJ-5 (1955-1971), and some military variants from the 1940s through the 1960s, featuring a 7.75-inch ring gear diameter, 10 cover bolts (typical Dana style), and commonly available ratios of 4.27:1 (standard), 4.88:1, 5.38:1, and occasionally 6.17:1 for low-speed crawling in off-road or steep terrain applications. Known for its durable semi-float design and straightforward serviceability, the Dana 25 remains popular among vintage Jeep restorers and flat-fender enthusiasts despite being phased out in favor of Dana 27/30 in later models—upgrades often focus on fresh bearings/seals, stronger axle shafts for modern tires, limited regearing due to limited ratio availability, or adding traction aids for better grip on trails. Browse a wide variety of high-quality Dana 25 axle components, including precision bearings, heavy-duty shafts, ring and pinion gear sets in available ratios, traction devices like lockers, and full overhaul kits, to help you rebuild, maintain, or strengthen your classic Willys Jeep for dependable performance on the road or off.
