Description

Built ground up for Ultra4 rock racers, the Spidertrax Ultimate Unit Bearing is truly the reinvention of the unit bearing itself. It features genuine Timken bearings, full chromoly heat-treated construction, and a fully integrated drive slug, making it a unique racing unit bearing. This unit bearing is designed to be the last one you'll ever need. It uses 5/8"-18 studs on a 6 on 5-1/2" bolt circle, specifically designed for Spidertrax 40 splined axle shafts. The drive cover is sold separately.
