This 40mm diameter shaft is precision-ground to ensure minimal runout, which is critical for achieving the high-precision balance required by modern automotive standards. The shaft is heat-treated for enhanced surface hardness, allowing it to support the weight of heavy wheels without bending or developing surface indentations. It is compatible with a wide range of standard 40mm adapters and cones. Regular inspection and replacement of the stub shaft are necessary to ensure that your balancer remains within calibration and provides the repeatable accuracy your customers expect.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eProduct highlights\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Ground:\u003c\/strong\u003e Minimizes runout for superior balancing accuracy and repeatability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e40mm Standard:\u003c\/strong\u003e Compatible with most industry-standard wheel balancer adapters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat Treated Steel:\u003c\/strong\u003e Provides the strength and hardness needed for heavy-duty daily use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect OEM Fit:\u003c\/strong\u003e Engineered specifically for Snap-On balancer models requiring this shaft.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e eam0021d90a\u003cbr\u003e\n\u003cstrong\u003eCountry of Manufacture:\u003c\/strong\u003e USA\u003cbr\u003e\n\u003cstrong\u003eShaft Diameter:\u003c\/strong\u003e 40 mm\u003cbr\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Stub Shaft\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eDirect replacement models\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSnap-On:\u003c\/strong\u003e eam0021d90a\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eYou will receive the same product or an OEM-Equivalent that meets the highest standard of the OEM with warranty that will be a direct-fit.
