The PMI Wide 50mm Axle Lock Collar delivers 35mm of robust, unyielding support to keep your bearings, hubs, and carriers locked dead-center under extreme lateral loads. When you are pushing the limits of your briggs and stratton lo206 horsepower, chassis flex and component shift are the enemies of speed. This two-piece, black anodized aluminum collar features a precision-machined slight shoulder that optimizes bearing alignment, ensuring your axle spins freely without binding. The integrated 8mm keyslot provides anti-slip security, clamping down with immense force so your driveline stays exactly where you set it.\u003c\/p\u003e\u003ch2\u003eDriveline Stability for High-Torque Go Kart Transmissions\u003c\/h2\u003e\u003cp\u003eModern racing demands absolute precision. Whether you are running a direct drive setup or managing the torque multiplication of advanced go kart transmissions, axle shift can lead to thrown chains, bound bearings, and scrubbed speed. The PMI wide lock collar's extended 35mm profile spreads the clamping force over a larger surface area of the 50mm axle. This prevents the collar from digging into the axle material while providing superior resistance against lateral thrust forces generated during high-G cornering. The split two-piece design allows for rapid installation and adjustment without the need to remove hubs, carriers, or slide components off the end of the axle—a massive time-saver in the hot pits.\u003c\/p\u003e\u003ch2\u003eSeamless Integration with Wheel Bolts and Wheel Accessories\u003c\/h2\u003e\u003cp\u003eA perfectly aligned rear track is essential for predictable handling. By locking your axle bearings and sprocket carriers firmly in place, this collar ensures that your rear track width remains consistent, allowing your wheel bolts and other wheel accessories to function without induced stress from axle deflection. The black anodized finish not only provides a premium, professional aesthetic but also protects the high-grade aluminum from corrosion and track debris. Although this specific wide-profile model is being phased out, its performance remains top-tier for racers needing maximum clamping force on heavy-duty setups.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e50mm Axle Compatibility:\u003c\/strong\u003e Precision-bored for a perfect fit on all standard 50mm racing kart axles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide 35mm Profile:\u003c\/strong\u003e Maximizes surface area contact to eliminate lateral component shift.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e8mm Integrated Keyslot:\u003c\/strong\u003e Locks securely into the axle keyway for ultimate anti-slip protection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo-Piece Split Design:\u003c\/strong\u003e Enables fast, hassle-free installation without disassembling the axle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMachined Alignment Shoulder:\u003c\/strong\u003e Facilitates perfect bearing contact to reduce friction and wear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlack Anodized Finish:\u003c\/strong\u003e Delivers a professional look while resisting corrosion and track debris.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Strength Aluminum:\u003c\/strong\u003e Provides robust clamping force without adding unnecessary rotational weight.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this collar compatible with all 50mm kart axles?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Yes, this collar is precision-bored to fit all standard 50mm racing kart axles.
