Our ZZPerformance upgraded lifter trays are the solution needed to complete your 3800 performance build. GM discontinued the OE lifter trays in 2023 so we knew we had to provide an upgraded product for the 3800 platform. Our lifter trays are CNC machined out of the same proprietary oil impregnated material we use in our supercharger coupler and Ecotec timing chain guide. This material features a lower coefficient of friction over the OE plastic trays ensuring your oil stays cleaner, makes more HP at high RPMs, and ensures worry free operation during the life of your vehicle. 

These lifter trays hold tolerance better than the OE trays so during high rpm situations where components vibrate and move around your lifters are held steady and more accurately on the cam, resulting in more HP and less wear. Check out the product photo which shows deflection differences simply from squeezing. OE trays hold much looser tolerances allowing the lifters to move around. 

Fits: Series II and Series III 3800 engines. Sold as a set. 

Installs exactly like stock, you will use stock bolts.
