Review on Optimized Timing Chain Kit for Ford TRITON 3-Valve F150 F250 Expedition | Includes Tensioner 🔧 Guides, Cover Gaskets, Cam Phaser, Engine Variable Camshaft Timing, VCT VVTi Actuator, Timing Sprocket Bolt, Gaskets by Chris Prix

After 5000 miles a timing chain tensioner failed and I also had to replace the crankshaft sprocket. The crankshaft sprocket that came with this kit is rubbish, I consider myself lucky that the tensioner failed, it gave me a chance to inspect the other parts that came with this kit. The crank timing looked worse than the factory which had 226,000 miles on it. This time I replaced it with a factory part and replaced the cheap plastic chain adjusters with factory cast iron assemblies. If you're looking at this kit because it's cheaper, save yourself the headache and buy factory parts. Keep in mind that I only put 5000 freeway miles on this kit before I had any problems. I hope this helps someone make a better choice than me.
