As drivers continue to push the boundaries of what’s possible, our Spider 9 products evolve to push those boundaries even further. We’re proud to release our latest Ultimate Knuckle, designed ground up to surpass the strength of our previous generation Pro Series Knuckle. Complete with 7/8″ spherical bearings, internal gussets, interlocking steering arm, and industry leading 50 degrees of steering, there are simply no shortcuts here. Take rock crawling and rock racing to new levels with the Spidertrax Ultimate Knuckle, now available on the Spidertrax Store.
