Get the SPEED and DURABILITY of STAINLESS STEEL for your Pinewood Derby Car now with the NEW Derby Worx Viper Pro SS Racing Axles. The new series of over-sized axles from Derby Worx are HANDS-DOWN the best axles we have ever tested and provide a distinct advantage over any other Pinewood Derby Racing Axle on the market today!

The increased size of the bearing area on the axle turns your Official B.S.A., Pinecar or Awana Grand Prix® wheels into a precision fitting race part for unmatched performance. These axles are precision machined from high quality 303 chromium-nickel stainless steel (that is magnetic) on a Swiss C.N.C Turning Center for watch-maker type precision and then custom media polished for a slick / non-directional finish.

They feature an over-sized .093″ bearing surface with precision placed friction reducing grooves for the Ultimate wheel hub to axle fitment, superior wheel stability and unmatched speed. The Main shaft is then reduced to a standard size .088″ so the Viper’s will work perfectly with the slots found in all brands of Pinewood Derby Kits using the Pro Axle Guide. For drilled axle hole and extended wheel bases, they work hand-in-hand with both the Derby Worx Pro Body Tool & Pro Body Jig for an excellent alignment!

The Derby Worx Viper Pro SS Axles are Race Ready right out of the bag, no additional finishing is required for excellent performance.

For Extreme performance Derby Champ recommends finish polishing the Viper's to a super slick / friction-free finish using our 815 micro polish to achieve a superior glossy finish. Next, polish and wax the wheel bores to a slippery finish using the 815 micro polish & 820 Pro Bore Wax and finally, lubricate with Krytox GPL 100 Racing Lubricant.

NOTE: Derby Champ & Derby Worx recommend either the “Pro Rail Rider Tool” or “Pro Axle Bender” for finishing tuning to a Rail Rider® alignment for maximum speed and performance.

Nice February 19, 2016
Reviewer: Robert Mykleby from Lacey, WA United States  
Fits great much less wheel wobble. When matched with either the Inertia Lite Speed Wheels - By Derby Worx or the Ultra Lite Speed Wheels - Premium Gold Edition - By Derby Worx they took first place in the pack with the inertia lites and my car in the open was even quicker with the ultra lites but by only 0.02 seconds.
