Knuckles, End Cups and Hardware

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" (22.2mm) spherical bearings & 4340 Spider Shoulder Bolts, exactly like our previous generation Pro Series Knuckle. 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 Pro Series Knuckle, there is no rock crawl or rock race these knuckles can't handle.

This Ultimate Knuckle works with Ultimate Unit Bearings and is designed to install on a Spider 9 Housing with 3 1/2" (88.9mm) OD tubes.
