THE “HYDROSOLID”

IS IT HYDRAULIC? OR IS IT SOLID? This amazing tappet has broken the barriers of previous tappet designs. This tappet performs like a hydraulic tappet from start up to about 5500 RPM, and then turns into a solid from 5600 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 tap- pet 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. Must use with adjustable pushrods.

*IMPORTANT NOTE: Preliminary tappet adjustment will make the pushrod tight. You must wait 5-15 minutes or longer to fully bleed off the hydraulic tappet (Tappets come pre-oiled). It is very important that the engine is not rotated while pushrods are tight. The pushrod will spin with your fingers after the tappet has bled off. Never turn the engine over if the tappet will not spin with your fingers after adjustments were made.
