Remark: Idler Sprocket & Blance Shaft Gears are not included. The camshaft sprocket in this timing chain kit only works with the NGC power control module. There are two types of PCMs (Powertrain Control Module): JTEC and NGC. JTEC is the older controller, and NGC is the newer controller. There is an easy way to tell the two apart: an NGC PCM has four connectors on it because it integrates the TMC (Transmission Control Module), while the JTEC has three connectors on it because it uses a separate TCM. Please make sure that your engine has the NGC controller before making the purchase.This item includes:1 Timing Chain Lower (primary 70 links)2 Timing Chain (cam drive 94 links)2 Tensioner (left & right)1 Guide Rail Right (right chain fixed rail)1 Guide Rail Left (left chain fixed rail)2 Guide Rail (left & right tensioner rail)1 Cam Sprocket Right (26 teeth has reluctor ring)1 Cam Sprocket Left ( 26 teeth - NGC power control module)1 Crank Sprocket (25 teeth)1 Idler Sprocket (primary 50 teeth)Idler Sprocket & Blance Shaft Gears - are not included1 Water Pump w/ Gasket1 Timing Cover Gasket Set1 Silicone SealantCompatible With / Replacement For Following Models:2004-2007 DAKOTA 3.7 SOHC 12V VIN "K" - NGC DESIGN2004-2007 DURANGO 3.7 SOHC 12V VIN "K" - NGC DESIGN2007 NITRO 3.7 SOHC 12V VIN "K" - NGC DESIGN2005-2007 RAM 1500 3.7 SOHC 12V VIN "K" - NGC DESIGN2006-2010 COMMANDER 3.7 SOHC 12V VIN "K" - NGC DESIGN2005-2010 GRAND CHEROKEE 3.7 SOHC 12V VIN "K" - NGC DESIGN2004-2010 LIBERTY 3.7 SOHC 12V VIN "K" - NGC DESIGN2006-2009 RAIDER 3.7 SOHC 12V VIN "K" - NGC DESIGN
