USAC Karting Rules & Technical Information

Karting doesn't need another new rulebook. For that reason, USAC is partnering with the National Karting Alliance and will be using the 2019 NKA Rulebook which is available online for free. Click Here to download the NKA Rulebook. 

Essentially, the NKA rules are very similar (or the same) as other rulesets. Briggs & Stratton publishes and owns the rights to all Briggs 206 engine tech. If you have any questions, please email them to

Special event rules, those specific to each individual event and/or class, will be published below in PDF format and on the specific event page and/or below.

Print this and insure your kart is in compliance with all safety tech specifications. Random checks will be performed throughout the weekend, and karts out of compliance will be subject to penalty.
