TECH TIP
Are link-bar style hydraulic roller lifters inherently noisier than OE style drop-in lifters?
Typical performance upgrades including high lift camshafts, roller rockers, and increased spring pressure can result in increased valve train noise. But, all other things being equal, all link bar lifters are likely to be slightly noisier than OE style drop-in lifters just by virtue of the link bar. Due to production tolerances, there must be a certain amount of clearance between the link bar, the lifter body, and the fastener (bolt or rivet). This clearance can allow the link bar to rattle during operation. Since the roller faces are typically crowned to prevent edge riding on the cam lobes, the lifters often oscillate slightly as they reciprocate in the bores. This can also cause a slight amount of noise. By controlling tolerances, we can reduce the link bar clearance in order to minimize the noise, but binding must be avoided. The is particularly important in big block Chevy V8 applications. Since the intake and exhaust lifter bores aren’t in line, the link bar to body clearance is constantly changing as the lifters move up and down in the bores. In addition, the link bars can’t be flat and straight due to the lifter bore geometry, so more clearance is required to prevent binding at the extremes of the lifter travel. For a high quality link bar hydraulic roller lifter, any additional valve train noise is inherent to the link bar style design, not the quality of the lifter itself.

TECH TIP
Do your GM LS drop-in lifters (GP1012) work in small block Chevy V8 engines that were originally equipped with roller lifters?
No, we don't recommend it. Our competitors use a compromise design to fit both engines. We don't. Since the engine lifter bore/oil feed geometries are much different between those two engines, we optimized the lifter design for each engine configuration.

GP1012 - 1997-Up GM Gen III & IV LS, Gen V LT V8
GP1013 - 1987-2002 Chevrolet 305-350 V8 (Originally equipped with roller lifters)

What's the weight of your lifters?

The weight of our lifters is shown in the following table.
All the lifter weights shown include fluid. The weight of retrofit and tie bar lifters is calculated by weighing a pair of lifters and dividing it by two.

TECH TIP

There are lifters shown online under the name Gatorman Retrofit Hydraulic Roller Lifters selling at a reduced price. The name is spelled similar to yours, but it's not exactly the same. Are those your lifters?

We don't sell to the online dealer offering lifters under the brand name Gatorman. We've asked our major distributors and they aren't selling to them either. We don't know whose lifters they are, but they aren't Gaterman Products lifters. So, if you want genuine Gaterman lifters, stay away from them.

TECH TIP

Do your small block Ford V8 retrofit lifters (GP1003) require a special small base circle camshaft?

No, they don't. During the early development of roller lifters for non-roller small block Ford V8 engines, the stock Ford factory roller lifters were used in conjunction with special hardware and a small base circle camshaft. We modified the design of our GP1003 retrofit roller lifter body to enable it to work with standard size base circle camshafts in the early small block Fords that originally used flat-faced lifters, later model blocks that came from the factory with roller lifters, and aftermarket blocks. No special small base circle camshafts are required.
