These axles are a MUST! Each set of axles is made using the parts found in the Official BSA® Grand Prix kit. Thunderbolt speed axles have a trade marked anti-friction groove that reduces friction and also serves as a graphite storage bin, to help keep your wheels lubricated throughout the entire race. The head of each axle has also been slightly tapered to further eliminate friction. Polish them up a bit starting with ultra fine 1500 grit sandpaper and they are ready go! Take home the trophy with Thunderbolt Speed Axles!

Speed Tip: For top performance use the ultra fine grit sandpaper found in our Axle Polishing Kit.

Testimonial: WOW... Just thought you would like to know that we just got back from a statewide race. The First, Second, Third, and Fourth place cars were all running Thunderbolt Speed Axles! Thanks!
