Among a number of products being manufactured today, we have Side A in progress for our Ultimate Unit Bearings. These are machined out of a solid piece of domestic grade chromoly steel with multiple CNC operations, heat treatment, and post heat-treat machining for those extra precise surfaces. Yes, a lot goes into this part.

Always nice to see.

Always nice to see.Now these are the kind of returns we like to see. In preparation for King of the Hammers, Jason Scherer shipped back his Spider 9 IFS parts for general inspection. Best he knew, parts were just fine, but for a race like King of the Hammers it’s always best to be prepared.

So, after a season of Ultra4 racing, including the top honors spot Jason grabbed at The PSC Brawl in Blackwell, how well did his Spider 9 IFS prototype parts hold up? In one word, flawless.

All four Ultimate Unit Bearings are as tight as the day we shipped them, and shafts are straight as an arrow. Since parts are already torn down, we’ll set Jason up with two new IFS stub shaft bearings and seals just to be safe, but that’s it. These parts are ready for another season.

Always nice to see prototype parts in action, handling their job as they were intended. That’s our look back, time to move forward. Back to work we go.
