The NEW Pre-Bent Derby Worx Viper Stainless Steel 2-Groove Axles are the most advanced Pinewood Derby axles on the market. They are exactly like our Derby Worx Viper Stainless Steel Speed Axles but these axles are slightly pre-bent (canted) with a precise 3.0 degree bend in order to decrease friction and increase speed! These axles come highly polished (up to 6,000 grit) and also have grooves to serve as lubrication reservoirs and to reduce wheel to axle contact.
Typically, both rear axles are bent so that the wheels will migrate away from the car body in order to eliminate the wheel to body friction and increase speed. The dominant front axle is also bent so that you can easily adjust the alignment of the car to either roll perfectly straight or to turn the car into a Rail Rider and significantly improve speed.These super fast axles come already bent so that you can quickly and easily install and blow the doors off of the competition.
You will also receive an instruction manual that explains how to install and adjust these axles in order to optimize performance.
OLD PROBLEM: The official BSA Pinewood Derby wheels and axles simply do not fit each other very well at all. The wheel bore is much larger than the diameter of the axle shaft. This creates a sloppy fit and causes the wheels to wobble as the car races down the track. This wheel wobble severely decreases speed.
NEW SOLUTION: These Pre-Bent Derby Worx Viper Stainless Steel 2-Groove Axles are the answer. Not only are they pre-bent to help you reduce friction but they also fit the inside of the wheel bores better. The upper axle shaft diameter is .093” to make a perfect fit to the BSA Pinewood Derby wheel hub. The lower shaft is .088” in diameter to fit both drilled axle holes and standard BSA Pinewood Derby axle slots. The axles are highly polished to a super slick sheen. These axles virtually eliminate all wheel wobble and highly reduces friction thus greatly improving the car’s speed.
