It's a direct-fit replacement for a wide range of GM applications, including the 2000-2005 Cadillac DeVille, 2006-2011 Cadillac DTS, Chevrolet Avalanche 2500, Express 2500/3500/4500 and Silverado 1500/2500/3500 (HD and Classic), Suburban 2500, GMC Savana 2500/3500/4500, Sierra 1500/2500/3500 (HD and Classic), Yukon XL 2500, and the 2003-2009 Hummer H2 — see the Buyer's Guide tab for the full list of 37 applications.
