Spidertrax Off-Road Ultimate steering knuckles set the standard for rock crawling and rock racing performance. They now include 7/8 in. spherical bearings and 4340 Spider shoulder bolts across the line. In addition, they feature internal gussets on both upper outer knuckle and lower inner knuckle, adding crucial strength from extreme steering forces and those high impacts from jumps. Ultimate knuckles are designed for Ultimate unit bearings, Ultimate U-joints, and 4140 bolt-on high steer arms (sold separately). They install on any Spider 9 housing with 3 1/2 in. O.D. tubes. * CNC-machined: Tight tolerances are necessary for proper fitment. Post welding, all inner knuckles are CNC-machined. This provides not only a perfect 7/8 in. spherical bearing fit but a precise tolerance between upper and lower spherical bearings. No guesswork, no compromise. * 7/8 in. bolts and bearings: The spherical bearing assembly consists of a 4340 Spider shoulder bolt, shim washer, spherical bearing, shoulder washer, and Type C nut. Combined, each knuckle can withstand over 21,500 lbs. of axial loading and over 130,000 lbs. of radial loading. No grease, no weak links, no hassle. * 50 degrees of steering: An OEM-style 60 knuckle can turn only 38 degrees. Ultimate knuckles can turn all the way to 50 degrees, tighter than any steering knuckle on the market. Plus, the use of a 6-bolt interlocking chromoly steering arm makes them one of the strongest, as well (steering arms sold separately). * Internal gussets: Ultimate knuckles take performance to an all-new level with the addition of internal gussets. Upper outer knuckle gussets add critical strength for steering, while lower inner knuckle gussets add extra strength for those high sailing jumps. They're simply Spidertrax's strongest Ultimate knuckle yet.

The last thing you would ever want is failure in a steering component. Spidertrax Off-Road's Ultimate High Steer Arm kits go above and beyond the competition in providing the safest and strongest steering arm available today. They start with only the finest U.S. grade 4140 chromoly steel and CNC-machine every arm to guarantee a perfect fit on every Spidertrax Ultimate Knuckle. Each arm is heat-treated after machining, never before, making it the strongest high steer arm on the planet. Spidertrax goes to great lengths in keeping your drag link and tie rod mounts parallel to the ground, providing the maximum amount of strength and articulation in your steering joints. In addition, every arm has three 5/8 in. diameter mounting holes for your drag link so each application can be dialed in perfectly. To keep your steering arms secure at all times, every arm uses six 1/2 in. bolts that exceed Grade 8. In addition, every arm has an interlocking keyway that secures it to the top of your Spidertrax Ultimate Knuckle. Additional notes: * Kits are available separately for driver or passenger side * Complete with arm and six matching bolts and lock washers * Designed and intended to use on Spidertrax Ultimate Knuckles for bolt-on steering
