Keep the cylinder head firmly clamped to the engine block with the APEX Automobile Parts Inc Cylinder Head Bolt Set, part number AHB371. It fits many vehicles with the V8-4.8L, V8-5.3L, V8-5.7L, and V8-6.0L engines, among them the 1999-2004 Chevrolet Silverado 1500 (V8-4.8L, V8-5.3L) and the 1999-2004 GMC Sierra 1500 (V8-4.8L, V8-5.3L).
Head bolts fasten the cylinder head to the block. They supply the clamping force that holds the head gasket in place between the two surfaces. If you are removing the cylinder head or replacing a head gasket, a fresh set of head bolts is a common part of that job.
Applications span Chevrolet, GMC, Cadillac, Buick, Hummer, Isuzu, and Pontiac models, among others. Fitment varies by year, model, and engine, so see the Buyer's Guide tab for the full list of years, models, and engine codes.
