This lifter is modeled after the Comp 875 lifter but it has more travel
range for more installation flexibility. They give higher RPM power w/o the noise
of other aftermarket lifters.
Below is a description between the differences of the standard Comp OE Lifter compared to the OE-R. This lifter is inbetween the two where you get the feel and sound of an OE lifter, but more of the performance of the OE-R lifter without the drawbacks of the OE-R. The OE lifter is slightly better than an OEM lifter.
OE lifters are a performance replacement for stock hydraulic roller lifters. Preload is meant to be setup similar to stock. Like stock, they are a ball valve style lifter.
OE-R lifters are specifically designed to perform at higher engine speeds. When engines are equipped with a hydraulic camshaft, high rpm is limited by the improper position of the internal piston as the lifter inevitably "pumps up". This improper location results in open valves and therefore leads to lost power. These lifters are almost required for any 3800 car shifting above 6000rpm because they help with the typical 5600rpm dip. OE-R lifters are preloaded and have to be installed between 3/8 and 3/4 turn (vs. 1/2 to 1.5 turns on stock lifters). These are a shim valved lifter like the ZZP and LS7 lifters. They have less range adjustment so preload is more difficult to setup.
