Overview
Spidertrax Off-Road Ultimate Unit Hub Assemblies
Built ground up for Ultra4 rock racers, Spidertrax Off-Road Ultimate unit hub assemblies are truly the reinvention of the unit bearing itself. Genuine Timken bearings, full chromoly heat-treated construction, and a fully integrated drive slug makes the Ultimate unit bearing the only racing unit bearing of its kind—the last bearing you'll ever need. They use 5/8 in.-18 studs on a 5-on-5 1/2 bolt circle, designed specifically for Spidertrax 40 splined axle shafts. Drive cover sold separately.
* Compact: With a span of just 2.125 in. from flange to wheel mount, the Spidertrax Ultimate unit bearing is the perfect fit for an Ultra4 solid or IFS (independent front suspension) axle.
* Powerful: Spidertrax eliminated the need for a drive slug, packed in 40 splined axle splines, all while adding a 4.235 in. hub register for wheel centering and strength.
* Secure: Spindle nuts are not only thread-locked into place, Spidertrax also uses a keyed lock ring. This means never having to worry about loosening spindle nuts.
