Axle Shaft Assembly

Engineered for ideal strength off-road and optimized for use with larger tires, Spicer nickel chromoly axle shafts are trusted for vehicles including Jeep. With factory-quality built into every Spicer part, you get an axle shaft that fits your off-road vehicle and delivers original performance. Manufactured from SAE-4340 Nickel Chromoly Steel. Not all chromoly shafts are alike. SAE-4340 nickel chromoly axle shafts are engineered to exceed factory standards and meet the exacting demands of off-road. Nickel provides additional toughness, Chromium ensures high-temperature strength and resistance to abrasion, and Molybdenum helps maintain a specified hardenability that is ideal for these specific parts. Spicer nickel chromoly steel axle shafts are also put through rigorous heat treatment processes to ensure optimal hardness throughout the part, offering the same surface hardness and case hardness while achieving higher core hardness, providing even greater strength for confidence on the trail. Designed to deliver added strength and durability, these genuine Spicer axle shafts are one more example of the innovations we bring to performance applications. That's why we include them on our Ultimate Dana 44™ and Ultimate Dana 60™ axles.
