SpiderTrax starts with only the finest US 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.
They go to great lengths in keeping your drag link & tie rod mounts parallel to the ground, providing the maximum amount of strength and articulation in your steering joints.
To keep your steering arms secure at all times, every arm uses six 1/2 bolts that not only exceed grade 8, but are all cross drilled for safety wire. In addition, every arm has an interlocking keyway that secures it to the top of your Spidertrax Ultimate Knuckle which is included with the Spider 9 Roller Kits.
Spidertrax 4140 Ultimate High Steer Arm Kits come complete with passenger or driver arm and six matching bolts and lock washers.
