A Builders Guide To The Hottest Parts

If you're looking to make upgrades and repairs to your old tired axles or to rebuild junkyard iron, or you need complete replacement assemblies, then you just got lucky! We've gathered a few new products from the top axle and axle-parts manufacturing companies and put together this giant guide. If you don't find what you need, then check out the websites or give them a call.

1. 4x4 Posi-Lok

The Alloy USA '03-'06 Jeep Wrangler Rubicon chromoly Dana 44 front axle kit includes 4340 Chromoly shafts that are up to 40 percent stronger than stock 1040 axles.

The kits include everything you need to complete the job: both passenger- and drive-side inner and outer axleshafts, seals, U-joints, and clips.
