There was a time when Jeeps and other trail rigs had little aftermarket support in the way of axle upgrades. The best and beefiest option back then was to find some Dana 60 axles at a salvage yard and either cut down the tubes or simply run them wide. When you snapped shafts or bent an axle tube, you ordered the same part that broke, straightened the tube, and put it all back together. These days, the options are numerous. We have high-strength front and rear axleshaft kits backed by multi-year warranties and heavy-duty, bolt-in axle assemblies that will seemingly never break, bend, or explode. You can now replace your broken or failure-prone parts with something substantially better without building a custom salvage yard Dana 60. Check out the following to read how.
