JIMS Powerglide Steady Roll Tappet, Standard, Harley 84-00 FX 84-99 FL 86 - 94 XL
The same Powerglide advantage (oil-fed axle, billet steel body, precision fit hydraulics), but now incorporates a Steady Roll bronze bushing in place of the needle bearing roller
These tappets have undergone extensive development to increase load, lubrication, hydraulic and life capacities
Billet body
Increased roller width
Roller perpendicularity held to .0002"
Hand-honed hydraulic unit cavity
Dynamic load capacities increased over 30%
Lubrication capacities for hydraulic unit and valve train (top end) increased 10%
Lubrication capacities for the roller, cams and cam bearings have increased 100% for increased cooling

S&S CYCLE Hydraulic Tappets, 4-Pack, specific application, Harley 84-00 FX 84-99 FL 86 - 94 XL
Rollers have a larger-than-stock inner bearing race that reduces stress and increases axle life
Each lifter body and plunger assembly is hand-fit and pressure-tested to ensure correct operation
Redesigned plunger assembly withstands forces associated with heavy-duty valve springs and pushrods typically used in high-performance applications
Revised metering device precisely controls oil delivery to top end, ensuring rapid lifter pump-up and reducing possibility of oil starvation to bottom end
