We start 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. We 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. In addition, every arm has three 5/8 inch 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 inch 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. Spidertrax 4140 Ultimate High Steer Arm Kits come complete with passenger or driver arm and six matching bolts and lock washers. These kits are designed and intended for use on Spidertrax Ultimate Knuckles.
Spidertrax was founded in 1999 by two New Jersey guys who met each other in vocational school and who both were really into off-roading. Thomas Kingston is an mechanical engineer and Eddie Casanueva is a manufacturing engineer. Their engineering backgrounds combined with their love of off-roading is the key to Spidertrax innovative products. Eddie and Thomas custom produce mods for their own Jeeps. Then they run those mods up and down rock crawling trails until the mods fail. Then they meticulously examine the exact cause of the failure. They then incorporate a solution to the failure into the product design before starting mass production. The Jeep way of build-break-repeat is the very process that brings the quality to Spidertrax products. Shop Spidertrax Offroad Now
