The standard in Kid Kart racing is PKT's 25mm x 970mm hollow chromemoly axle with a wall thickness of 3.0mm only weighs 3.1 lb. . Reduce your rotating weight by up to 4 lbs. over OEM solid steel axles.
The new 970mm length allows maximum track width while using the narrow Kid Kart wheels and hubs.
This is a "Hard" axle with a lower flex rate than the 2.1mm axle.
Use PKT Key 6 x 60 for all components locations.
