When you are pushing the limits of your chassis, even a fraction of a millimeter of slop in the kingpin assembly translates to unpredictable steering feedback and scrubbed speed through the apex. This Performance Manufacturing 1\/2\" ID Kingpin Washer Kit provides the exact shimming tolerances needed to lock down your front end, ensuring that every steering input is directly transferred to the track surface.\u003c\/p\u003e\u003ch2\u003eMaximize Chassis Efficiency and Briggs and Stratton LO206 Horsepower\u003c\/h2\u003e\u003cp\u003ePower delivery isn't just about tuning your go kart clutch or optimizing a belt drive system; it's about maintaining momentum. If your spindles are shifting under load, you are bleeding valuable speed. By utilizing this comprehensive 38-piece shim kit, you can perfectly align your kingpin bearings, reducing rolling resistance. This means you can maximize every ounce of your briggs and stratton lo206 horsepower, carrying higher exit speeds without fighting a wandering front end.\u003c\/p\u003e\u003ch2\u003ePrecision Shimming for Go Kart Wheels Tires and Alignment\u003c\/h2\u003e\u003cp\u003eProper caster and camber settings are useless if the spindle assembly shifts during high-G cornering. Whether you are running high-grip sprint compounds or standard go kart wheels tires, this kit allows you to fine-tune the vertical play on 1\/2\" kingpin bolts. The combination of 1\/16\" and 1\/32\" washers gives mechanics the micro-adjustment capabilities required for professional trackside tuning. Track conditions change rapidly, and having the right hardware on hand is critical for any serious competitor. This kit is a staple for any go karts supply box, ensuring you are never caught off guard during practice or qualifying sessions. Proper spindle shimming also extends the lifespan of your kingpin bearings by preventing uneven load distribution, saving you from costly mid-season rebuilds and keeping your kart on the track where it belongs.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e1\/2\" Inner Diameter:\u003c\/strong\u003e Precision-stamped to fit standard 1\/2\" kingpin bolts with zero radial slop.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e7\/8\" Outer Diameter:\u003c\/strong\u003e Provides optimal surface area contact for kingpin bearings and spindle yokes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e36 Heavy-Duty 1\/16\" Washers:\u003c\/strong\u003e Forms the robust foundation for major gap bridging and structural support.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2 Micro-Adjustment 1\/32\" Washers:\u003c\/strong\u003e Allows for ultra-fine tuning to eliminate the final thousandths of an inch of vertical play.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Chassis Kit:\u003c\/strong\u003e Includes enough hardware to fully shim and rebuild both left and right spindle assemblies.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriction Reduction:\u003c\/strong\u003e Prevents binding in the steering yoke, ensuring smooth, predictable steering inputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Compatibility:\u003c\/strong\u003e Engineered for seamless integration with modern sprint, oval, and enduro racing chassis.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I know if I need to shim my kingpins?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e If you notice vertical play or \"slop\" when grabbing the top and bottom of your front tires, your kingpin assembly likely needs shimming.
