With back to back rock racing competition coverage, we haven’t had a chance to share the exciting news on our Pro Series Housing. Already a staple product in the Ultra4 scene, the all new Pro Series Housing takes off-road racing to the next level. Today’s Pro Series Housing is stronger (heat treated tubes, accepts 9″ & 10″ gears), more versatile (68″ OAL, works with standard and mid-engine setups), and just down right sexier (tig finished, machined face) than any housing we’ve ever created. In stock, with same day shipping, be sure to check it out over at http://www.spidertrax.com/Spider9-Housing-65C35YT .

Just about everywhere you look, the Spidertrax machine shop is in full Spider 9 production mode. King of the Hammers prep is clearly underway, and with roughly 3 weeks left till race day, the clock is ticking for many. We’re here, when you’re ready, hopefully making that prep just a little bit less stressful.
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.

What better way to complement a day of pre-running and qualifying than with a little show and tell. We’re bringing out our latest IFS creations to show off this Friday at the PSC Brawl in Blackwell. For those starting a new build, or thinking of doing so, you’ll definitely want to check this out. See you out there!

Looking to build that perfect Spider 9 axle? We’ve just made some updates to our Spider 9 calculator that will ensure you get the job done, right. The image above is a screen shot from the calculator itself, and hopefully from the image you can tell it’s pretty easy to use. Simply enter in the “Given”, namely the wheel mount surface (WMS), A, and the locker type. With just those three pieces, we fully dimension out the housing, tube cut lengths (Ta & Tb), shaft lengths, and pinion offset for all of our different hub configurations (Ultimate Unit Bearing, 1 Ton Unit Bearing, or Pro Series Hub).
The calculator was created in Excel, so you will need Excel or a program that can work with Excel files (like Mac’s Pages). Head over to our SUPPORT page where the both front and rear calculators can be downloaded.
That’s it for today. Have a great holiday weekend and a quick reminder we’ll be closed this Monday for Labor Day.
