A must-have replacement if you’re still running the weaker LS1 style lifter trays. These are a drop-in replacement for all LS engines and a must have preventative measure against engine damaged cause by lifter rotation sometimes found when using the older style lifter trays.
Stock replacement for LS2, LS3, LS7, L98, upgrade for LS1, LS6, LQ9, etc. Will not work with AFM or DOD applications.
Sold individually, four required per engine. Like GM Part #12595365
