It provides the linear force and alignment necessary for the chuck jaws to grip the wheel rim securely during service. Precision-machined from high-strength alloy steel, the rod is designed to withstand the immense tensile and compressive loads generated by pneumatic or mechanical clamping systems. Its smooth surface finish ensures low friction during actuation, while its dimensional accuracy guarantees a direct fit within the chuck body. A bent or worn rod can lead to improper wheel centering or slipping, which can cause damage to the rim and inaccurate results during balancing or tire mounting. Replacing the rod is an essential maintenance step to ensure that the chuck assembly maintains its original grip strength and alignment accuracy for safe wheel service.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eProduct highlights\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamping Essential:\u003c\/strong\u003e Provides the central force and alignment for the wheel chuck assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Strength Steel:\u003c\/strong\u003e Resists bending and deformation under heavy clamping pressures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Machined:\u003c\/strong\u003e Ensures smooth movement and a perfect fit within the chuck body.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecure Grip:\u003c\/strong\u003e Critical for maintaining wheel alignment and preventing rim slippage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Construction:\u003c\/strong\u003e Built for millions of cycles in high-volume automotive shops.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Chuck Assembly Rod\u003c\/li\u003e\n\u003cli\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Snap-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e ST4013916\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eDirect replacement models\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eSnap-On ST4013916\u003c\/p\u003e\u003cp\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.
