Have the ability to get on and off the trail every time. If it’s off-road reliability that you’re searching for, install one of these bad boys on your rig and hammer down with less worry. The only true solution to driving as hard as you want is quality parts built to withstand abuse.
Crane Axle’s heavy-duty 14 Bolt Axle Assemblies start with a Brand New USA Made 14 Bolt Axle Housing that is cast from high-strength nodular iron. Our team expertly machine presses 4” x ½” (.500”) wall DOM Tubes into that housing for increased strength to resist bending & torsion. From there, the axles are assembled to your chosen Specs.
100% designed, manufactured and assembled in the USA
Crane Axle Inner C’s, Knuckles, and Diff Cover
Cast from 8620 Chromoly Steel
We start with the finest domestic grade 8620 chromoly steel and have our Magnum Knuckles cast in the USA. This allows for strict quality control and for a better end product.
After casting, each part is individually CNC machined for maximum precision. Our process systems ensure a consistent end product every time.
MIG Welded Install
The Magnum Inner C’s are expertly MIG welded by our fabricators to your 4” x ½” (.500) DOM Tubes. Once these things are burned on, they aren’t going anywhere.
We can safely say we stand by our products because they have been tested in the roughest of riding. From trail riding to rock racing, these knuckles will hold up. Crane Axle Inner C’s and Knuckles can be seen on the rigs of racers such as Bubba Bacon, Randall Key, Wes Kean, and more. These guys abuse and put these knuckles to the test. This includes use in Southern Rock Racing Series, Pro Rock Racing, and Ultra 4.
