DEFEND INDUST Hydraulic Roller Lifters & 4 Guides Set16 New LS7 LS2 16 GM Performance 12499225 HL124

Definitely worth the price and I got in a timely manner! Very happy with my purchase

I used 12 of these in a supercharged 06 Grand Prix. They came pre charged with oil. I had no taps on startup. I am pleased ad I used them in place of 38.00 EACH oem lifters, with a little pn research. THEY ARE NOT LS7 LIFTERS.THEY DO NOT HAVE THE NOTCHES BUT THEY ARE PERFECT FOR ANY GM UNDER LS7

The kit I receive held the lifters too loose which can cause the lifter to not be stable while traveling up and down from cam lob and rocker tension from valve springs. It looks factory but may need to reconsider the clearance.

Lifter trays were garbage, would not hold the lifters in place or keep them from turning on you. The lifters suck, they bleed down fast, minutes after shutting the engine off, you can restart and they clatter until oil pressure hits them again. Don’t waste the money on these. The amount of work and money for new bolts and gaskets to replace these is not worth the purchase. I wish there would have been a review like this prior to me wasting my time and money for what looked like a good product.

The lifters are decent. Don’t use the lifter trays though or you’ll be pulling the head’s again. They hold the lifters extremely loose save you’re the hassle and go OEM on the trays.
