HELL NO!!! Zero stars! Total scam!!
Just spent 3 days taking this car apart only to have these lifters fail!!!!! I do not have the time to do this again!! Total junk! I am beyond pissed off! Someone better get ahold of me on this! 3.4 stars? False advertising! Zero stars! Do not buy! A total waste of time! I will be adding pictures as soon as I get it apart! Total scam! Ps. Amazon is making me put 1 star.

Garbage
I don’t udhsllg leave reviews but these lifters are junk you would think I would learn to quit trying to save a buck by buying parts on Amazon but I’ve bought other jdmspeed items with no problem. Installed these and one of the lifters failed within an hour of use. I emailed them and the response I got was can you send us a picture showing failure. Really? So now I’m stuck having to buy another lifter and gasket set in order to fix it

1 star purchase don’t trust
Definitely wouldn’t buy again. Got everything put together and boom still ticking, when I pulled the driver side valve cover cylinder 1s exhaust push rod has a solid stream of oil coming out. One of the AFM lifters is faulty causing me to have to do the job half over again. DO NOT BUY!!!

3 of the DOD valves exploded in 4 pieces after the engine ran for 10 minutes
Extremely horrible quality parts from this seller, honestly makes me want to never order parts from Amazon again!! Do yourself a favor and save yourself from having to do this job over again. Do a DOD delete or use quality DOD lifters that are melling or acdelco!!

Horrible quality
O stars. The quality is horrible. A lot of play on the cylinders. Installed it and the truck was worst than before and a lot of tap/noise lift. Buy from the OEM. One time job opposed of twice labor fees
