We have another fun prototype project we’ve been working on. Complimenting the Narrowed IFS Diff from last week, we put the finishing touches on our prototype Pro Series IFS Unit Bearing. Designed with Ultra4 IFS in mind, these all new unit bearings are 1″ more compact from WMS to CV flange per side over our current setup. In addition, combined Pro Series IFS Unit Bearing and axle shaft is 4lbs lighter per corner over our existing Ultimate Unit Bearing & axle shaft (that weight saving includes the addition of the drive snout as well). These prototype Pro Series IFS Unit Bearings were a blast to work on, we’re excited to see what will come of it. Until next time, make it a great weekend!

We had a lot of fun working on this new prototype narrowed IFS diff. Built for Ultra4, this diff is 1.4″ narrower than our current IFS housing, includes internal shell gussets for that extra bulk-head smashing drivers like to do these days, and in typical fashion face and bearing bores are all machined post welding. With that, back to work we go and make it a great weekend!

We’re working on a new IFS bulk head. Changes go beyond just cosmetic, this bulk head ends up being quite a bit larger than the existing one. Sometimes you have to go big to go small. More details to follow.

We’re having some fun with a new weld-on high steer arm design for our Pro Series Knuckles. The video above and the few photos below do a better job than my typing, so I’ll leave it at that. Hope you enjoy this project as much as we did, with that have a great weekend (and best of luck to all Ultra4 racers at Dirty Turtle!).
