Fusion HP Dana 60 Super Kingpin Front Axle - 3.5" or 4" Tube

Sku: FUS-SKP60

Product Number: FUS-SKP60
Brand: Fusion

For current axle lead times and shipping details:  See this page

The Fusion Super Kingpin HP60 is designed for those looking for the largest and strongest high pinion 60 axle in the industry.       

All tubes are cut to length and machined in-house. Assemblies are pressed together, plug welded, and then 360 welded to the cast and C's using a semi-automated welding process to ensure high quality welds that look bad ass. We use only USA made and sourced DOM for our tubes.

Please call or email us with your specs: width, drop, offset, caster/pinion separation. If you have a reference axle, that makes it even easier (e.g. 78-79 Ford Sno Fighter).

What makes the Super Kingpin so great?

  • It's big, really f-ing big
  • Kingpin assembly, which means no ball joints to replace or wear out
  • Utilizes the stout Dana 60/70 upper and lower kingpin assemblies for the utmost in strength
  • 1.5″ increased yoke spread allows fitment of 1480, 1550, and Rockwell 2.5-ton U-joints and a greater load carrying capacity
  • Uses OEM 2005-present Ford Superduty unit bearings, lockout hubs, stub shafts, U-joints, and 2005-2012 calipers and rotors
  • Outer stub shafts can be oversized to directly engage the unit bearing’s 2.5-inch hub splines when the lockout components are removed
  • Flat-top pad machined for 6 ARP high steer studs, allows for aftermarket steering arms that provide a wide range of steering options
  • Knuckles cast from high-strength ductile iron and beefed up with extra material and ribbing
  • Cast-in steering arms tapered from the top down for standard “1-ton” tie rod ends; extra-wide arms allow the tie rod holes to be drilled out for oversized bolts, heim joints, etc. Extended arms allow a straight tie rod to clear most differential covers
  • 100% Made in the USA
