Why get R lifters instead of the Comp OEM replacements?
What is it structurally or technically that makes the comp R lifters better than the OEM replacements? Everyone always talks so highly of them but never explains why.

Re: Why get R lifters instead of the Comp OEM replacements?
The Comp R lifters act like a solid lifter at higher rpms. I'm guessing that the internal plunger is stiffer than OEM replacements.
This is a quote from Summit: "These Comp Cams Pro Magnum hydraulic roller lifters are specifically designed to perform at higher engine speeds. When engines are equipped with a hydraulic roller camshaft, high rpm is limited by the improper position of the internal piston, as the lifter inevitably "pumps up". This improper location results in broken valves, and therefore leads to lost power or sometimes even engine failure. These lifters offer a distinct advantage over standard high-performance hydraulic lifters, especially in race applications where a hydraulic lifter must be used."
And amean94ta,
