Revolution Gear and Axle Discovery Series D30 Front Axle Kit HD U-Joints

Revolution Gear and Axle Discovery Series 4340 Chromoly Front Axle Kit, fits 2007-18 Jeep Wrangler JK Sport and Sahara Models with Dana 30 front axle and 27 Spline axles. This Front Axle Kit replaces the Spicer 1350 Style 5-7166X U-Joint with Revolution Gear and Axle's Heavy Duty Chromoly 1350 Style Needle Bearing U-Joints creating the strongest axle setup and allows extra clearance for tighter turning versus the smaller 5-760X U-Joint.

Note: Revolution Gear and Axle Discovery Series Axles are backed by a 10 Year Warranty covering manufacturing defects and axle breakage, bent axles and twisted splines. This warranty is non-transferable. U-Joints are only covered under warranty against manufacturing defects for 1 Year (Front Axle Kits with Revolution Gear HD Chromoly U-Joints carry a limited 10 Year Warranty). Parts subject to normal wear are not covered under warranty; this includes bearings and seals. Revolution Gear and Axle reserves the right to either axle replacement or credit after the first warranty claim.
