If you're running bigger tyres, a lift, and actually using your Jeep off-road, the factory Dana 30 axles are going to be your weak point sooner or later. This Rough Country 4340 Chromoly Front Axle Kit with Grizzly Locker is the proper fix — up to 50% stronger than stock, built to handle the punishment that Cherokee XJs, Wrangler TJs, YJs, and Grand Cherokee ZJs dish out on the trails.

The 4340 chromoly construction is the real deal for serious builds. You get 30 spline inner axles and 27 spline outer axles, plus everything you need in the one kit to get it done properly.

  • 4340 chromoly axle shafts — up to 50% stronger than factory
  • Grizzly Locker included for maximum traction
  • Includes inner and outer shafts, U-joints, axle seals and disconnect delete kit
  • Fits Dana 30 front axles: XJ, ZJ, TJ, YJ
  • 5-year warranty against manufacturer defects

As NZ's official Rough Country importer, Magwarehouse stocks these ready to go. Give the team a call on 09 250 1803 or come into our Manukau workshop to sort your Jeep's drivetrain properly.
