Engine Cylinder Head Bolt Set, Victor Reinz 14-10071-01 (Discontinued)

engine cylinder head bolt set using new head bolts when performing a cylinder head installation is always a good idea however, on late-model engines that came from the factory with tty (torque-to yield) head bolts, replacement is an absolute necessity. Tty bolts are designed to exert the maximum clamping force for a tight head gasket seal, however they permanently stretched and could fail if re-used. aplication summary: avanti - 2001-04 ii v8 5.7l, buick - 2004 rainier v8 5.3l, cadillac - 2004 cts v8 5.7l, 2002-04 escalade v8 5.3l, 2002-04 escalade v8 6.0l, 2003-04 escalade esv v8 6.0l, 2002-04 escalade ext v8 6.0l, chevrolet - 2002-04 avalanche 1500 v8 5.3l, 1998-02 camaro v8 5.7l, 1997-04 corvette v8 5.7l, 2003-04 express 1500 v8 5.3l, 2003-04 express 2500 v8 4.8l, 2003-04 express 2500 v8 5.3l, 2003-04 express 2500 v8 6.0l, 2003-04 express 3500 v8 6.0l, 1999-04 silverado 1500 v8 4.8l, 1999-04 silverado 1500 v8 5.3l, 2003-04 silverado 1500 v8 6.0l, 2001-03 silverado 1500 hd v8 6.0l, 1999-00 silverado 2500 v8 5.3l, 1999-04 silverado 2500 v8 6.0l, 2001-04 silverado 2500 hd v8 6.0l, 2001-04 silverado 3500 v8 6.0l, 2003-04 ssr v8 5.3l, 2000-04 suburban 1500 v8 5.3l, 2000-04 suburban 2500 v8 6.0l, 2000-04 tahoe v8 4.8l, 2000-04 tahoe v8 5.3l, 2003-04 trailblazer ext v8 5.3l, gmc - 2003-04 envoy xl v8 5.3l, 2004 envoy xuv v8 5.3l, 2003-04 savana 1500 v8 5.3l, 2003-04 savana 2500 v8 4.8l, 2003-04 savana 2500 v8 5.3l, 2003-04 savana 2500 v8 6.0l, 2004 savana 3500 v8 4.8l, 2003-04 savana 3500 v8 6.0l, 1999-04 sierra 1500 v8 4.8l, 1999-04 sierra 1500 v8 5.3l, 2001-04 sierra 1500 v8 6.0l, 2001-03 sierra 1500 hd v8 6.0l, 1999-00 sierra 2500 v8 5.3l, 1999-04 sierra 2500 v8 6.0l, 2001-04 sierra 2500 hd v8 6.0l, 2001-04 sierra 3500 v8 6.0l, 2000-04 yukon v8 4.8l, 2000-04 yukon v8 5.3l, 2001-04 yukon v8 6.0l, 2000-04 yukon xl 1500 v8 5.3l, 2001-04 yukon xl 1500 v8 6.0l, 2000-04 yukon xl 2500 v8 6.0l, hummer - 2003-04 h2 v8 6.0l, isuzu - 2003-04 ascender v8 5.3l, ponti
