This pneumatic cylinder is responsible for actuating the jaws of the wheel chuck, providing the clamping force required to hold the rim securely during high-torque tire changing operations. Designed for the rigorous demands of professional automotive service, this cylinder features high-quality seals and a precision-ground rod to ensure smooth operation and long-term durability. A weak or leaking chuck cylinder can lead to wheel slippage, which can damage the rim and pose a safety risk to the technician. Replacing the cylinder with this OEM-quality component restores the machine's clamping performance to factory standards, ensuring that you can handle even the most difficult tire and wheel combinations with confidence.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eProduct highlights\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecure Clamping Force:\u003c\/strong\u003e Provides the powerful grip necessary for safe tire service operations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmooth Actuation:\u003c\/strong\u003e Precision-engineered for consistent and reliable movement of the chuck jaws.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Construction:\u003c\/strong\u003e Built to withstand millions of cycles in a high-volume shop environment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeak-Free Reliability:\u003c\/strong\u003e Features high-quality internal seals for long-lasting pneumatic performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Integration:\u003c\/strong\u003e Engineered specifically for Snap-On wheel clamping systems.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\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 ST4031521\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Chuck Cylinder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Reference:\u003c\/strong\u003e K5610-V2\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eDirect replacement models\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eSnap-On K5610-V2, ST4031521\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.
