VIPER Pro SS 2 Groove

Derby Worx 2 groove pinewood axle – Viper Pro Stainless Steel Speed Fast are designed with only one thing in mind… sheer speed. They are exactly like our Pro Tech Stainless Steel Speed Axles but these axles have grooves to serve as lubrication reservoirs and to reduce wheel to axle contact.

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 Derby Worx Viper Stainless Steel 2-Groove Axles are the answer. 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. These axles virtually eliminate all wheel wobble thus greatly improving the car’s speed.

2 groove pinewood axle – Viper Pro Stainless Steel Speed Fast are machined of high grade stainless steel. These axles are not only corrosion proof but are also crimp free and highly polished making them race ready and super fast. The shaft has two grooves to serve as lubrication reservoirs.
