Sometimes old school rules.

November 24th2015

Let’s see how good your memory is, for you faithful blog followers. Back in June of 2014, we helped design and manufacture a custom “Wide 5 Edition” Ultimate Unit Bearing. Part of a very unique IFS project fueled by Ben Bower himself, these Wide 5 bearings getting closer to finding their home onto the custom IFS billet outer bell, as shown in the video above. Just love the old school rotary table here, fancy CNC machines make things easier (and faster), but traditional manual machines can get the job done as well.

Be sure to check out Ben’s YouTube channel, not only does he share the inner workings of this IFS project but he’s also an avid wheeler and rock racing junkie.

Spidertrax Ultimate Unit Bearing (6 on 6-1/2" x 5/8" Studs x 35 Spline)

When we set out to build the ultimate line of Ultimate Unit Bearings, offering a variety of wheel bolt patterns was on the top of that list. Continuing with that goal in mind, we are excited to add a 6 on 6-1/2″ bolt pattern option to the family. Complete with 5/8″ wheel studs, and available in both 35 & 40 splined options, this new Trophy Truck inspired Ultimate Unit Bearing could easily be one of the most popular we see in Ultra4 racing.

35 spline option available HERE.

40 spline option available HERE.

Happy Friday!
