Revolution Gear and Axle D30 27 Spline Axle Kit - Front

Revolution Gear and Axle D30, 4340 Chromoly US Made Front Axle Kit for 1997-06 Jeep Wrangler TJ, LJ, 27 Spline kit without Locker. 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 Revolution Axles are backed by a fantastic lifetime warranty against failures, including but not limited to U-Joint failure.

Revolution Gear and Axle USA MADE Axle Kits 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 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.

Specifications:

A: Factory Dana 30 axles are made from lower-strength materials and can be prone to bending or breaking under stress. The Revolution Gear 4340 chromoly shafts offer significantly higher strength, making them ideal for larger tires, lockers, and off-road abuse.

A: Yes, these chromoly shafts are a popular upgrade when stepping up to larger tires (typically 33"–35" and beyond), helping prevent axle breakage during off-road use.
