DOD/AFM Disabled Kit With Camshaft Lifters Compatible with 2007-2013 Chevrolet Avalanche Silverado Tahoe, GMC Yukon Sierra 5.3L Truck/SUV Engines

This is worse piece of crap, I’ve ever bought, I have been building engines for about 30 years, decided to go with this, because of the price, new everything, put in the truck, oil pressure kept dropping, engine chattering, checked oil, it’s metal flakes, took it apart cam bearings destroyed, needless to say, had to do everything again, dealer cam and lifter, engine runs great, please don’t buy this crap, Amazon should be sued for selling this.

Good kit as the other negative review on here you NEED to remove AFM that comes with a new tune and is not included in this kit

The kit looked great when I unboxed it. However lifters were noisy even after following directions by manufacturer eventually one of them failed with less than 300 miles on it

Good kit but was missing 1 of the orange gaskets for block of plate can't finish engine build untill I can find o specific o ring or install freeze plugs

funciona exelente

One star is too much im a profesional and would not recommend this kit at all. The problem is the camshaft is trash. It loses all the oil pressure and that's y this kit is trash i had to get a New cam from the dealersgip and all the problems when away. Don't speed your money buying this kit

Great way to get rid of those dod lifters and make it run right again. Kit contained everything in it to do the job even the gaskets. Once the vehicle was reprogrammed it ran good as new!

After installing this cam kit misfires on all afm cylinders (1,4,6,7) unable to contact manufacturer.this has cost me 20+hrs of time plus hundreds if not thousands of dollars
