Conventional Hydraulic
Lifters
|
||
Speed-Pro hydraulic lifters are precision manufactured to maintain precise valve timing under all operating conditions. A patented constant orifice metering valve provides precise oil metering to the overhead valve train. Longer plungers or pistons provide increased bearing surfaces resulting in longer lifter life. Check valves are lightweight, flat discs allowing higher speeds and more uniform operation than other lifter brands. The lifters below are intended for use with both OEM and aftermarket stock camshafts. Also recommended for use with hydraulic performance camshafts with RPM limitations of between 5500 and 6000RPM. Conventional hydraulic lifters can be identified by the prefix SPHT. | ||

Hi-Rev Hydraulic Lifters
|
||
Speed-Pro Hi-Rev (commonly called anti-pump up) hydraulic lifters feature the same quality material and construction as the conventional hydraulic lifter. A special high strength steel retainer is used in place of the normal spring clip to precisely limit the travel of the plunger during operation. With plunger travel limited, adjustable rocker arms must be used to effect a lash adjustment of .000/.002. This then allows the valve train to perform more like a mechanical system, thus allowing high RPM operation. Because of the high RPM capability and the elimination of frequent lash adjustments (which are required with mechanical lifters), Hi-Rev hydraulic lifters are the best chioce for all-round performance. Hi-Rev hydraulic lifters can be identified by the prefix SPHT and the suffix R. | ||

Mechanical Lifters
|
||
Speed-Pro mechanical (fixed) lifters are manufactured from high quality iron alloys to withstand design stresses and normal engine contamination. Material and design excellence provide a lifter that is lightweight yet exhibits superior strength. A patented oil metering system limits the amount of oil that reaches the overhead valve train. This keeps as much oil in the crankcase as possible while providing adequate lubrication to the valve train. Heat treated pushrod seats are used to eliminate wear from push rods in racing engines with high valve spring pressures. Speed-Pro mechanical lifters are intended for use with cast iron camshaft billets only and can be identified by the prefix AT. | ||

** NOTE: Edge Orific lifters restrict oil supply to the Rockers.
Reccomended for use with Roller Rockers. Do not use edge orifice lifters
with an oil restrictor kit. Must check that the lifter oiling hole is exposed
to the lifter gallery. |
