Jims Powerglide Hydraulic Tappet. Standard .9035" OD for Harley-Davidson

With clearance up to approximately 0.700" at the lift cams, clearance should be checked with the performance cams.
Weight 143 grams each.
Jims Powerglide™ tappets will give you superior hydraulic function compared to OEM-style equipment, featuring a hand-polished billet steel body, hydraulic unit cavity, and an oil-fed shaft.
To achieve maximum power, you must have zero valve lash and eliminate hydraulic unit collapse as found in the OEM unit, also known as "damper syndrome." The total amount results in a loss of power.
Jims Powerglide tappets are as close to a solid tappet as possible, but can still compensate for heat expansion.
They will even work well with solid style camshafts.
Fits as an upgraded direct replacement for OEM 18526-89.
