excellent product highly recommended

They seem to be good I just installed them along with a melling high volume pump and new cam not sure if I can give an update on this platform or not

Worked okay

After less than 100 miles of being installed in the vehicle, the product came apart, causing damage to theft, camshaft and push rods as well as the lift yoke breaking and the retainer clip to come loose. Inside of the engine spent 12 hours and two days on the phone to get nowhere and constantly hung up on due to the failure of the item as well caused my vehicle to shut down, unable to restart and almost caused a life-threatening accident. Amazon refuses to do anything for the repairs or the fact that it could’ve killed me. There is no manufacturer information except for Amazon so I believe the next step I would have to take is a lawsuit against the company. All that I am trying to request is Amazon supply the parts for the repairs and yet they refuse to do anything so so what could have been a couple hundred dollars in parts for them as soon to come into a couple thousand if not more lawsuit

Muy mala calidad no sirven
