disappointed
The publication did not indicate the amount of valve lift was buying, I assumed that, as my vehicle uses 6, was buying set of 6, but it was not, I got just one. Both process and wait for now only have one, and now I have to stay detained by this detail, to return to make the purchase of the rest

FROZEN LIFTERS
PUT THESE IN MY TRUCK. PUT IT BACK TOGETHER AT LEAST 3 WHERE FROZEN! FIRST TIME AND A LAST TIME! NEVER AGAIN. LEARNED MY LESSON. HAD TO PUT THEM IN A VISE TO GET THEM TO PLUNGE. VERY EXPENSIVE AND LABOROUS!!!

Worked like factory on a stock cam
Had zero issues with these lifters, they did come packaged in a way I found suspicious and was explained as they’re “purchased by bulk” put them in a 2007 Tahoe and the worked flawlessly. Drove the truck for another 18 months and sold it. Still see it around town. All these negatives reports make me wonder if I didn’t dodge a bullet. But they worked as good as any GM lifter I’ve ever used before and I use many.
