  • (2) 2005+ Super Duty Unit Bearing Adapters
  • All Required Hardware

Engineered for extreme off-road applications, Crane Axle’s Magnum Knuckle Aluminum Unit Bearing Adapters seamlessly integrate the robust 2005+ Ford Super Duty unit bearing with our Magnum Outer Knuckle. This setup delivers one of the strongest, most compact steering knuckle assemblies on the market.

Designed for the harshest rock-crawling and racing environments, these adapters reduce unsprung weight and simplify maintenance while accommodating massive drivetrain power. 

Whether you are building a Magnum Knuckle setup or adapting a modified 2.5-ton Rockwell knuckle, this system creates a hybrid axle solution with modern serviceability, superior bolt strength, and a standard 8x6.5" bolt pattern.

Key Features & Benefits: 
  • Adapts 2005+ Super Duty Unit Bearing to Magnum Outer Knuckle
  • Works with Modified Timken 2005+ Super Duty Unit Bearing
  • Compatible with 2.5-Ton Rockwell Knuckle Conversions (with modification)
  • Simplified Maintenance: Uniquely designed to allow RCV Big Bell axle shaft installation without disassembly.
  • Modern Performance: Compact, lightweight, and stronger than traditional spindle setups.
  • Complete Package: Includes all necessary mounting hardware.
  • Made in the USA

Compatible Bolt-On Brake Kits

Technical Note: 

Easy Shaft Installation Traditional setups often require you to break down the CV joint to get the shaft into the housing. Our Unit Bearing Adapter is machined with a larger internal bore, allowing you to slide a complete RCV Big Bell axle shaft directly into the housing without disassembling the boot. This feature significantly speeds up assembly and field repairs.
