†Item shown in picture may not represent exact product .
These are premium quality USA made hydraulic flat-tappet lifters. They are made from a low-porosity casting with the correct hardness for compatibility with US made aftermarket flat tappet camshafts, and assembled with heavy-duty internals that meet or exceed OE machining tolerances. They feature a Patented 4-Hole metering disc and an ultra-thin check valve disc for increased RPM potential and quick response. They do all of this while not requiring any special pre-load settings and retaining the quietest operation* of any aftermarket hydraulic lifter. This makes them ideal for both stock replacement or a modified hotrod engine.
DETAILS
Make: Chevrolet
Engine: 1955-1995 Chevy 262-400 Gen I Small Block V8 (w/o factory roller camshaft)
1958-1965 348-409 'W' Mk I Big Block V8
1965-1995 396-454 Mk IV & V Big Block V8 (w/o factory roller camshaft)
Type: Hydraulic Flat-Tappet
Style: Performance
Anti-Pump: No ('anti-pump' lifters have very shallow pre-load settings, requiring semi-regular valve train adjustment, and make more tappet noise)
Face Oiling: On PN 5205HL only
Maximum RPM: 6000 RPM**
Quantity: 16
Notes: The Hi-Lube option delivers extra oil from the oil band to the lifter face using an oiling flat precision ground partway down the side of the lifter. It also features a specially divided oil band to ensure the lifter internals are still fed the correct amount of oil. They may result in a nominal drop in oil pressure.
*Lifter noise is not solely a product of lifter valving. Other variables include: cam lobe design (lobe major intensity), lobe base circle size, spring pressure, rocker configuration, and proper adjustment. Aftermarket cams are inherently noisier than stock cams due to faster lobe ramps/higher lobe intensity, & heavier valve springs. Some lobe designs are far noisier than others (e.g. our SR series, Comp Xtreme Energy™, & Lunati Voodoo™), these cams will be noticeably noisy even with a quiet lifter.
**Suggested maximum RPM only, based on lifter valving. Other factors such as spring pressure, valve train weight, rocker ratio, and lobe stability play a large role in RPM potential. You may be able to turn more or less RPM than listed.
