We offer Johnson / Topline "Hylift" American Made Heavy Duty Standard Hydraulic Lifters. Great quality at a great price. Use these with both stock and most performance cams under about .510" lift, especially if you are using non adjustable factory stamped steel type rockers. These work great for up to 5500 RPM. If you intented to go beyond that point, then we recommend going with our "anti pump up" style of lifters along with an adjustible valve train such as roller rockers, etc.
Not all lifters are created equal. Comp's "High Energy" hydraulic lifters are their version of standard non "anti-pump up" style lifters. They are produced with a longer piston than conventional lifters, and also feature a lightweight check valve disc that allows for quicker response, and added oil control at all engine speeds and loads. Use these Comp High Energy Hydraulic lifters with stock, stamped steel type rocker arms, with cams .510" lift or less, in applications which the engine will see less than 5000 RPM. For applications above 5500 RPM (or for any type of racing applications,) cams above .510" lift (which generally will use dual valve springs,) we highly recommend their "Anti Pump up" style Pro Magnum Lifters, (Listed separately.)
Comp's Pro Magnum (Anti Pump Up Style) premium hydraulic lifters are the recommended choice for all the Comp Hydraulic cams we sell above. These are mandatory for any type of racing use, or in any application in which the engine will see over 5000-6000 RPM. At these higher RPM's Comp has done extensive testing. They have found not only were the Pro-Magnums good for about 10-15 more horsepower, but they also do not succumb to lifter "pump-up," a condition where the internal piston inside the lifter can fill up with oil and not have enough time to drain or "bleed down." This can result in the piston being in an improper position as it "pumps up," which can lead to holding valves open, which in turn can lead to greatly reduced power output, or in some cases (if that open valve happens to strike a piston top) there can be extreme engine failure. These must be used with an adjustable type of valve train, such as adjustable rocker arms (preferably roller rockers) along with the associated pushrods required. These lifters are considered essential to ensure that your cam has the longest possible life and is fully covered under Comp's warranty policy. And, since this is Comp we're talking about, you can be assured of two things: The product is 100% made in the USA, and the quality is second to none.
Howards Cams 100% USA Made retrofit hydraulic roller lifters are true high performance street lifters designed primarily for ease of maintenance and reliability. They "drop into" a stock block with no machine work or oil system mods required, and work with all the steel billet hydraulic roller cams we sell, regardless of brand. The lifters are CNC-machined and then fitted with precision check ball internal valving to prevent lifter "pump up." These features combine to provide a broader power band and increased rpm potential, while still offering the low maintenance of a hydraulic cam. These are designed for street performance enthusiasts who want to upgrade to a hydraulic roller camshaft. They are manufactured to fit early or late model blocks, including blocks with tall lifter bosses. Howards Cams uses cold form technology to shape their bodies for durability. The lifters are then carbonitrided and tempered for hardness. They also feature hardened and tempered steel alloy roller wheels, heat-treated stainless steel cross bars, and high-alloy steel tie bar buttons. Howards Cams Street series retrofit hydraulic roller lifters are specifically designed for street applications up to 6,500 rpm.
Trick Flow's 100% USA Made retrofit hydraulic roller lifters are true high performance street lifters designed primarily for ease of maintenance and reliability.

Along with the purchase of any Comp cam and lifters, we also strongly recommend using Comp's engine break in oil additive. This is it essential to make sure your cam and lifters are fully covered under Comp's warranty. It's a well known fact that, due to EPA regulations and other reasons, over the last few years oil manufacturers have removed the Zinc and other additives from their motor oil. If you try to break in a brand new cam and just add regular "off the shelf" motor oil from your local parts store, it is VERY likely you will have a failure. You must add this additive to the oil to replenish the zinc which is no longer included by the oil manufacturers. This works with synthetics, blended, and standard petroleum oils. In our own engines, we usually get a couple extra bottles to keep on the shelf and add one at every oil change. It's cheap insurance.
Comp Cams has taken great pains to develop what they feel to be the best line of lubricants available to protect your engine before startup and during break-in. Used by professional engine builders throughout the country, their cam and lifter lube is a red tacky oil which sticks to the surface and won't bleed off. This is ideal for engines which will sit for any amount of time between initial startup and when the cam and lifters were installed and lubed. This ensures your cam and lifters have full lubrication upon startup, preventing any galling or scuffing upon first contact. One 4oz bottle is enough to do one engine.
