Hearing a rattling noise from the front of your 3.7L engine, especially on startup? It's a common issue, and often means the timing chain and guides are worn out. This complete timing chain kit from CNS is designed to fix just that. It fits a bunch of vehicles with the 3.7L VIN K NGC engine from 2004-2013, including the Dodge Dakota, Durango, Nitro, Ram, and some Jeep models. The kit includes the crucial parts: the timing chain itself (94 links, 50 teeth) and the timing chain guides. It's a direct replacement for OEM numbers like 53021294AA and supersedes several others (like 9-5458). The CNS part number is TK74. This is a major repair that restores proper engine timing and quiets down that noisy valvetrain. It's a brand new kit in its packaging. A word for California buyers: there's a Prop 65 warning about phthalates. This job is best for experienced DIY mechanics or professionals, as it requires significant engine disassembly. But if you're tackling it, using a complete kit like this ensures you have all the wearing parts replaced at once, saving you from future headaches and another teardown.
