Spidertrax Ultimate Knuckle (3.5 in.) Mild Steel, Bolt-On Steering
Since 2007, our fabricated knuckles have set the standard for rock crawling and rock racing performance. Our latest generation Ultimate Knuckle takes this standard to an all new level. Ultimate Knuckles now include 7/8" spherical bearings & 4340 Spider Shoulder Bolts across the line. We didn't stop there though. Our Ultimate Knuckles now include internal gussets on both upper outer knuckle & lower inner knuckle. These gussets add crucial strength from extreme steering forces and those high impacts from jumps we all love to do. Designed to surpass the performance of our previous generation knuckles, there is no rock crawl or rock race these knuckles can't handle. This Ultimate Knuckle is designed for Ultimate Unit Bearings, Ultimate U-Joints, and 4140 Bolt-On High Steer Arms (sold separately). Installs on any Spider 9 Housing w/ 3-1/2" OD tubes.
