The valve uses steel construction and a coated finish, with dimensions that support correct fitment in engines that require a 1.72 in. head diameter, 5.355 in. length, and 0.372 in. stem diameter. The 45-degree seat angle helps maintain proper contact at the valve seat, while the material selection supports heat exposure common to exhaust service. Part number V1261 is a practical choice for rebuilds and maintenance work where original-style valve geometry is required.\u003c\/p\u003e\u003cp\u003eThis part cross-references Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Is Used For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacing a worn or heat-damaged exhaust valve\u003c\/li\u003e\n\u003cli\u003eRestoring valve sealing in a stock engine rebuild\u003c\/li\u003e\n\u003cli\u003eAddressing compression loss caused by valve wear\u003c\/li\u003e\n\u003cli\u003eCorrecting exhaust-side sealing issues from pitting or recession\u003c\/li\u003e\n\u003cli\u003eSupporting proper valve train operation in older Chevrolet and GMC engines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify head diameter, stem diameter, length, and seat angle before installation. This valve is listed for stock applications and for certain optional Stellite configurations, so match the engine specification carefully before assembly.
