Frequently Asked Questions
Will this COMP Cams product fit my 1999-2002 GMC Sierra 2500 SL?
That application is listed, but confirm the exact engine family, valvetrain, cylinder head, cam specifications, supporting parts, and manufacturer part number.
Are valve springs or other supporting parts required?
Requirements depend on the exact camshaft and engine combination. Verify springs, retainers, locks, pushrods, lifters, rockers, timing components, clearances, and calibration before assembly.
Does installation require engine measurements?
Yes for most internal valvetrain work. A qualified builder should verify piston-to-valve clearance, spring pressure and travel, coil bind, retainer clearance, geometry, lash or preload, and cam timing.
Installation Instructions
Follow the current COMP Cams and engine-manufacturer instructions for this exact part number. Verify clearances, spring pressure and travel, geometry, lash or preload, fasteners, lubrication, cam timing, break-in, and calibration requirements before assembly. Inspect and test the completed installation before full-load operation.
