spare parts installed. but motor is not working properly. long searched for reasons. in the end it turned out that the parts are defective and do not work as they should !! The motor was dismantled three times because of this !!! I can't return them! it's trash!!! Return the money!!!opened the old one to understand its work. and only after a long trial, they realized that the new ones are not working, at least 3 pieces !!!!

muy buen producto y rapido en entregas

Very good but 8 lifter is bad bad defect the one with the springs I put it on my truck and it want even move wow is parts from Amazon really good now I got to go to the dealership should have went there in the first

Good deal price

They fit great sound is a little louder then the originals but worked great

This is a total waste of money and time. Avoid these at all cost. Rebuilt top end of motor and used these Lifters. Didn't even last three miles down the road before one of the Lifters collapsed. Now I get to spend a lot more money tearing it back down and replacing with legit Lifters. These are such poor quality that my mechanic not only questioned me for buying parts online (🤦‍♀️) but if these were made with a 3d printer. I failed to read the prior reviews and hopefully you don't make the same mistake I did.

This item did not work correctly so I had to remove from my engine and return. Ended up buying from parts store

This is a labor intensive job, installing quality highly advised. These lifters should be banned. Horrible! Consider you have to purchase head bolts and gaskets when you open your engine. very expensive repair to fail before ever driving 50 miles. Wish I could leave negative stars. But they do fit the engine bore. I guess then can be used for display only?
