Overview

CNC & heat treat.

All components are CNC manufactured out of domestic grade 4130 chromoly steel, legs are now heat treated, and all inner knuckles are machined post-welding for a perfect spherical bearing fit. Every single part is made right here in the USA, no exceptions, no compromises.

7/8" bolts & bearings.

The spherical bearing assembly consists of a 4340 Spider Shoulder Bolt, shim washer, spherical bearing, shoulder washer, & type C nut. Combined, each knuckle can withstand over 21,500 lbs of axial loading & over 130,000 lbs of radial loading. No grease, no weak links, no hassle.

50° of steering.

An OEM style 60 knuckle can turn only 38°. Our Pro Series Knuckle can turn all the way to 50°, tighter than any steering knuckle on the market. Our unique fully integrated 4130 double shear high steer arms are perfectly integrated into the knuckle as well. Stronger steering, stronger knuckle.

Gussets & tig.

Upper outer knuckle gussets add critical strength for steering while lower inner knuckle gussets add extra strength for those high sailing jumps. Tig weld the entire knuckle with high strength high elongation filler rod and you end up with a product fit for the worlds toughest races.
