Ecotec Lash Adjusters

The ZZP Ecotec Lash Adjusters are a set of 16 metal, grey components designed as a performance upgrade for your vehicle's valvetrain. Modeled after the Comp 875 lifter, these ZZP adjusters feature a more extensive travel range, providing greater flexibility during installation. These lash adjusters are positioned as an improvement over standard OE lifters, offering the user experience and sound of an original equipment part but with the performance characteristics closer to an OE-R lifter, without the associated drawbacks. Unlike OE-R lifters which have a more limited adjustment range and require precise preload setup (often between 3/8 and 3/4 turn), these ZZP adjusters aim for a setup similar to stock, with preload meant to be established in a comparable manner. They utilize a ball valve style, akin to stock components, and are almost essential for vehicles operating above 6000 RPM to mitigate the typical dip experienced around 5600 RPM. Externally, these ZZP Ecotec Lash Adjusters resemble LS7 lifters and are compatible with a range of GM Ecotec engines. They are suitable for the 2011+ Regal LHU, as well as 2.0L LSJ, 2.0L LNF, 2.2L (L61, LAP), 2.0 LTG, and 2.4L LE5 engines. Like all valvetrain modifications, it is recommended to use a pushrod length checker to ensure proper installation and optimal performance.
