When you are pushing high RPMs on the track, excessive lateral movement in the crank can lead to catastrophic bearing failure, parasitic power loss, and inconsistent ignition timing. By utilizing this 4-piece shim set (25mm ID x 36mm OD), engine builders can dial in the exact clearances required to keep the rotating assembly perfectly centered, reducing friction and maximizing power transfer to the rear wheels.\u003c\/p\u003e\u003ch2\u003eEssential Tuning for Your Go Karts Frame For Sale\u003c\/h2\u003e\u003cp\u003eWhether you are prepping a fresh chassis or upgrading an older go karts frame for sale, blueprinting your engine is just as critical as mounting a top tire or dialing in your alignment. The ARC Racing shim kit provides multiple thicknesses, allowing you to stack and customize the fitment for various stroker crank configurations. This level of micro-adjustment ensures that the connecting rod stays perfectly aligned with the cylinder bore, mitigating piston side-loading and extending the life of your internal components.\u003c\/p\u003e\u003ch2\u003eOutperform Standard Brake Replacements and Bolt-Ons\u003c\/h2\u003e\u003cp\u003eWhile many racers focus on external upgrades like aerodynamic fairings or premium brake replacements, true track dominance starts inside the crankcase. Proper shimming reduces heat buildup and prevents the crank gear from walking, which is vital for maintaining consistent valve timing.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Tolerances:\u003c\/strong\u003e Engineered to exact 25mm ID x 36mm OD dimensions for a flawless fit on GX200 clone crankshafts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Thicknesses:\u003c\/strong\u003e Includes a 4-piece assortment of 1mm and 2mm shims to achieve the perfect end play clearance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriction Reduction:\u003c\/strong\u003e Prevents lateral crank walking, significantly reducing parasitic drag and internal heat generation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-RPM Durability:\u003c\/strong\u003e Manufactured from hardened steel to withstand the extreme torsional stress of modified racing engines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStroker Compatibility:\u003c\/strong\u003e Specifically tailored for aftermarket stroker cranks requiring custom block clearance adjustments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Alignment:\u003c\/strong\u003e Keeps the connecting rod centered on the wrist pin, reducing piston skirt wear and cylinder scoring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy Integration:\u003c\/strong\u003e Drops directly onto the PTO side of the crankshaft during standard bottom-end assembly.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eWhen you are chasing every fraction of a horsepower, details matter.
