Hydrosolid Tappet For Twin Cam 88 , Single

JIMS® Hydrosolid Tappet breaks the barriers of previous Tappet designs. It performs like a hydraulic Tappet from start-up to about 5500 RPM then turns into a solid above that, yielding up to 3-6 more horsepower. Requires use of adjustable pushrods. Additional hydrosolid fitments available. Replaces OEM #18538-99.

Powerglide™ Hydraulic Tappets for solid-type cams on Evolution® engines end Tappet noise forever! They yield zero valve lash and eliminate collapsing of the hydraulic Tappet. They are as close to a solid Tappet as possible while still compensating for expansion.

JIMS Solid Adjustable Tappets for XL and Buell® have a 4340 chrome moly steel screw with oil hole to feed the top end. Use with non-adjustable pushrods. These have clearance for about .700" lift cams. Oversize clearance units also available.
