Elgin Industries LS engine Active Fuel Management lifters with Guides are now available for 2007+ AFM applications. The lifter has (NEW DESIGN) ratcheting locks that will keep the lifter collapsed. The lifter spring will stay compressed to prevent the pistons from contacting the valves. This lifter design is a huge improvement over the old/troublesome design of the active fuel management lifters!
Made In USA
Remember, the spring on top of the lifter is a fuse designed by GM. If any spring ever becomes collapsed, then this lifter fuse is blown the same as an electrical fuse in the fuse box. Replacing the lifter will not solved the problem until the cause is found.
Typically, the lifter fuse collapses when the computer tells the lifter to activate during the incorrect valve timing. This prevents the valve from contacting the piston. the cause is usually a ground-fault-interrupt from the ECM or PCM in AFM Gen IV LS and DFM Gen V LT engines.
