The Spicer 1410 Universal Joint & U-Bolt Kit is a heavy-duty driveline solution built for rock crawlers, one-ton Jeeps, Ultra4 cars, trail buggies, towing applications, and high-performance off-road vehicles. Manufactured by Spicer, this kit combines a premium 1410 series non-greaseable universal joint with matching U-bolt retention hardware to provide maximum strength and reliability in demanding driveline environments. The 1410 series is widely considered the sweet spot in off-road driveline performance because it offers a significant strength increase over a 1350 series driveline while maintaining excellent driveline angles, articulation, and serviceability. The non-greaseable solid-cross design eliminates internal grease passages that can weaken the cross section of the joint, making it the preferred choice for competition vehicles and extreme-duty applications. Whether you're servicing an existing driveshaft or building a complete driveline system, this kit provides the strength and durability needed for serious off-road use.

The 1410 series uses a wider cross and larger overall footprint than a 1350 series joint, providing increased torque capacity and improved durability for heavy-duty off-road applications. Why choose a non-greaseable U-joint? Non-greaseable U-joints use a solid cross design without internal grease passages, resulting in greater strength and improved resistance to shock loads. What yokes does this U-joint fit? This U-joint fits standard 1410 series yokes, including Spicer 1410 carrier bearing yokes, driveshaft yokes, pinion yokes, and flange yokes. Is a 1410 U-joint good for rock crawling? Yes. The 1410 series is commonly used in one-ton Jeeps, rock crawlers, Ultra4 race cars, trail buggies, and high-horsepower off-road vehicles. Should I replace the U-bolts when replacing a U-joint? Yes. New U-bolts are recommended whenever a U-joint is serviced to ensure proper bearing cap retention and prevent future loosening.
