Driveline LC30B-WIDE Extra-Wide 30mm Axle Lock Collar - Dual 6mm/8mm Keyslot - All Classes

Locking down your rear axle assembly with these new kart parts ensures zero axial movement, delivering the rigid bearing support required for high-speed cornering. The Driveline LC30B-WIDE Extra-Wide 30mm Axle Lock Collar is engineered with a 35mm broad profile and an integrated shoulder that makes perfect, flush contact with kart bearings. By eliminating lateral flex and distributing clamping force evenly across the shaft, this collar translates your engine's output into pure forward momentum—crucial when maximizing your briggs and stratton lo206 horsepower on tight, technical circuits. When the rear end is fully stabilized, the chassis can flex exactly as the manufacturer intended, preventing binding and power loss.

Securing Your Drive-Line and Steering Components

While racers often obsess over front-end geometry, steering components, and high-performance master cylinder brake parts, securing the rear axle is equally critical for overall chassis stability. A shifting axle can throw off your brake rotor alignment, causing drag that robs you of top-end speed. This two-piece split collar allows for rapid installation or adjustments without removing the axle, cutting down crucial pit prep time between heats. Whether you are dialing in your setup with specialized tools tire pressure gauges or swapping out hubs for a changing track surface, this collar's dual 6mm and 8mm keyslots accommodate a wide variety of shaft configurations, making it a highly versatile addition to your trackside toolkit.
