Review on Enhance Engine Performance with Cloyes 9-0393SX Timing Chain by Roger Diaz

Purchased and installed during a 4.7 liter conversion for a 2002 Durango. The engine began to rumble on startup, hydraulic valve lifters thought. Find out, the chains are slack and the tensioners are fully extended. Either the chain is too long or the quality of this product is poor. Dismantled, put regular chains, guides and tensioners. The engine is now quiet during cranking and has been for the 20,000 miles I've driven it now. Do yourself a favor and buy OEM.
