PKT 30mm Axle Key - 6x60mm Dual 6mm Peg - Sprint/Endurance Racing

Eliminating driveline slop is the first step to maximizing torque transfer, and sourcing the right racing parts from a trusted kart store ensures your power gets to the pavement. The K2 Pegged Axle Key for 30mm PKT axles (6mm wide x 60mm long x .130" tall, dual pegs) is engineered to lock your hubs and carriers to the OEM K2 axle manufactured by PKT. That stops the micro-rotations that shear a standard key and sap acceleration out of tight hairpins. Use this key only where the hub has a 6mm keyslot.

Integrating with Your Go Kart Chassis and Driveline

When tuning your go kart chassis for flex and grip, the last thing you want is a sloppy driveline. This precision-machined K2 key uses two pegs that locate in the axle shaft. Whether you are dialing in go kart clutch engagement or swapping an accessory wheel hub, it removes rotational play so engine torque hits the wheels. Immediate throttle response is what you need in sprint racing. Some later-model K2 chassis use hubs that take an 8mm-wide PKT key. Do not run this 6mm key in those hubs.

Built for High-Stress Racing Environments

Standard keys deform under 2-cycle and 4-cycle load. Hardened construction holds up to vibration and shear in high-speed cornering and hard braking. If you have been searching for go karts for sale near me just to find an edge, start with the driveline you already have. A solid axle connection keeps the kart balanced, cuts chewed keyways, and keeps lap times consistent. Confirm the hub slot is 6mm before you install it.

• Exact Fitment: Fits the OEM K2 axle manufactured by PKT. 30mm axle. Hub must have a 6mm keyslot.
• Dual Peg Design: Two pegs lock into the axle and stop the key from walking.
• Optimized Dimensions: 6mm wide, 60mm long, .130" tall for full contact in a 6mm slot.
• 6mm Hubs Only: Later-model K2 hubs that take the 8mm PKT key need that key, not this one.
• Maximum Torque Transfer: Prevents hub slip on the axle so power goes to the track, not the keyway.
• Hardened Construction: Built for the shear load of sprint and endurance kart racing.
• Vibration Resistance: Stays indexed under high-RPM engine harmonics.
• Quick Maintenance: Slides the keyway for a fast gear or hub change in the pit lane.
