Revolution Gear and Axle D30, 4340 Chromoly US Made Front Axle Kit for 1987-95 Jeep Wrangler YJ 1985-92 Comanche MJ 1985-97 Cherokee XJ, 27 Spline kit with Disconnect Eliminator included. All Revolution Jeep Front Axle Kits come with 2 US Made 4340 Chromoly inner axles, 2 US Made 4340 Chromoly outer stub axles, 2 Dana Spicer 5-7166X U-Joints and 8 Full Circle Snap rings to hold it all together. Revolution uses the large 1350 Style U-Joint for all of our Jeep applications. Using the substantially larger 1350 Style U-Joint provides a substantial increase in strength over the smaller 5-760X U-Joint and allows extra clearance for tighter turning. All American Made Axles are backed by a Limited Lifetime Warranty covering manufacturing defects and axle breakage, bent axles and twisted splines. This warranty is non-transferable. U-Joints are only covered under warranty for 1 Year (Other than Revolution Gear HD Chromoly U-Joints). Parts subject to normal wear are not covered under warranty; this includes bearings and seals.
