It is listed for a broad range of Chevrolet, GMC, Buick, Pontiac, Oldsmobile, Jeep, and American Motors applications, including many classic Chevrolet C10, C20, K10, and Camaro fitments, as well as GMC Jimmy and Pontiac Firebird applications. Part number VS-170 is also cross-referenced to Monroe Shocks \u0026amp; Struts 172286 and 182286 for the same application.\u003c\/p\u003e\u003cp\u003eMelling’s spring lineup covers standard, mid-range, heavy-duty, and race-ready needs, and this part reflects that broad engineering approach in a standard replacement format. For buyers restoring or maintaining older Chevrolet and GMC engines, VS-170 provides a direct spring option where stock-style valve control is required. The part number VS-170 is useful when matching an existing specification or replacing a worn spring during engine service.\u003c\/p\u003e\u003ch2\u003eCommon Uses\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCorrecting weak valve spring tension\u003c\/li\u003e\n\u003cli\u003eReplacing fatigued or worn engine valve springs\u003c\/li\u003e\n\u003cli\u003eRestoring stable valve train operation in stock engines\u003c\/li\u003e\n\u003cli\u003eAddressing valve float concerns in service rebuilds\u003c\/li\u003e\n\u003cli\u003eMaintaining proper spring pressure during engine overhaul\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify installed height, coil bind clearance, and spring pressure before installation. Confirm camshaft and cylinder head requirements, especially on applications noted for specific camshaft use or fuel system exceptions.
