JIMS, popychacz hydrauliczny Powerglide. +.001″ o.s.

Clearanced up to about .700″ lift cams; still clearance with performance cams must be checked. Weight 143 grams each. Jims PowerglideT tappets will give you a superior hydraulic function when compared with OEM style equipment; a billet steel body with hand-honed hydraulic unitcavity and an oil fed axle. To get full power; you must have zero valve lash and eliminate collapsing of the hydraulic unit as is found in the OEM unit; also called ”the shock absorber syndrome”. Failing to keep the valve open the full amount results in power loss. The Jims Powerglide tappets come as close to a solid tappet as possible; but are still able to compensate for heat expansion. They will even work well with solid style camshafts. Fits as an oversized improved replacement for OEM 18526-89. Note: Standard diameter is .9035″.
