The Cobra is a full-sized clutch that weighs in at two pounds. It is a four spring, eight lever clutch and, just like all Jammer Clutches, it has a built-in keyway. It also includes our unique double-disc design with modified friction disc material for 100% lockup, yielding extremely fast starts.
Strike fast with the Jammer Cobra.
Jammer Clutches custom builds each clutch for the class the karter is going to race. There is no need for adjustment when you take it out of the box .. just bolt it on and go racing. Clutch engagement is factory set per class. All clutches are run on the Dyno before they are shipped so we know that the clutch is ready to race. Each kart clutch has its own serial number which is registered to the owner.
Because each clutch is custom built for you please allow 3-5 business days for shipment.
