The "Ultra-Short" rear wheel hub by PKT is the most narrow-width rear hub found in karting. At just 30mm wide, this hub is a very common site on front-running kid karts, and some cadet kart applications. In particular, if you run a 4-Cycle LO206 cadet, these might be just the ticket to free up an over-stuck chassis.
Each hub is CNC machined from aerospace-grade aluminum billett, and anodized for extra durability.
Each hub comes with milled key pathway for 6mm axle keyways.
Black, anodized finish with PKT logo laser engraved.
Each hub comes complete with (3) 4100 alloy heat-treated wheel studs installed, which will fit most kart rims (metric bolt pattern).
Available in multiple Inner Diameter (ID) configurations for different axle applications:
25mm (ID): This hub is designed to fit most Kid Kart axles, which are commonly 25mm in diameter.
30mm (ID): This hub is designed to fit (nearly) all cadet kart axles, which are almost always 30mm in diameter, as well as select Kid Kart axles.
1 1/4" (ID): While a rare application, this hub is designed to fit some "standard" go kart axles for American-made axles with a 1 1/4" diameter.
Hubs are sold individually, with included wheel studs and tightening bolt. (2) hubs are required to make use of these hubs on any kart.
