Smooth Power on Every Trail: Driveshaft Solutions for Your Jeep Wrangler YJ.
Due to its short-wheelbase configuration, the drivetrain of any 1987-1995 Jeep Wrangler YJ is highly sensitive to suspension changes. Installing a leaf-spring lift kit forces the factory rear driveshaft to operate at harsh angles, leading to severe driveline vibrations and accelerated seal wear at the transfer case output. Our online inventory features both premium standard replacement parts to restore factory smoothness and essential heavy-duty upgrades to handle extreme trail usage.
Trusted Trail Quality: RT Off-Road, Dana Spicer, and Crown Automotive Excellence.
The definitive fix for any lifted YJ is our RT Off-Road Slip-Yoke Eliminator (SYE) Kit, which replaces the factory slip-yoke style rear output with a rugged fixed flange. This setup allows for the installation of our heavy-duty RT Off-Road rear CV driveshaft (double-cardan), engineered to handle steep angles and high torque loads seamlessly. For front-end repairs, we stock complete front driveshaft assemblies from Crown Automotive along with protective rubber boots.
For mechanical durability, we strictly rely on the OEM standards of Dana Spicer for high-tensile U-joints (also available from NTY), strap kits, slip yokes, and input flanges (including full yoke kits from Crown). Our comprehensive range is finalized by target components like driveshaft oil seals, pinion nuts, crush sleeves, and a vast selection of speedometer gears to accurately correct your dashboard cluster after tire upgrades or axle re-gearing.
