Jims USA Hydrosolid Tappet

Performs like a hydraulic tappet from start up to about 5,500 RPM, and then turns into a solid from 5,600 RPM to your set RPM rev limiter. At the same time it becomes a solid, it also adds about 3-6 more usable horsepower. What this all comes down to is that about the time your springs start to surge and go into harmonic distortion and the tappet rollers start lifting off the back side of the cam, you can be at ease knowing that your JIMS Hydrosolid Tappet will not pump up, allowing your valves to hit.
