Product Description

Hylift Johnson has been manufacturing lifters in Muskegon Michigan USA for over 70 years and some of
their employees have been with them for over 50 of those years. They do all of the Design,
Engineering, Manufacturing, Assembly and Testing in-house so they can control the quality of
the product 100% and you can have 100% confidence in it. Hylift Johnson is dedicated to the
manufacturing of the best lifters available in our 167,000 sf facility in Muskegon. Their
employees operate super precision grinding equipment as well as multi million dollar assembly
machines that perform 20 quality checks on every hydraulic lifter. They also have a brand new
325,000 sf facility in Brooksville FL and are expanding their new manufacturing too instead
of following the acceptable practice of going overseas to save a dollar or less.

Hy-Lift Johnson only uses castings and forgings of the highest quality material that are 100%
made in the USA. Our casting supplier has been supplying us for more than 60 years. Yes we
pay more for our material than others pay for their material made overseas but we know that our
material is worth the extra money. We had casting suppliers from all over the world send us
samples to test and evaluate. In the end none of them came close to the endurance of our American supplier.

A lifter is only as durable as the material it is made from. It won’t matter how
much money you saved, how pretty it looked, or how shiny it was when you bought it, after it
fails in your engine. Make sure you ask your Lifter supplier where their material came from.
They might say that they are manufactured in the USA but if the material came from overseas
you will end up getting what you paid for!

These two lifters underwent the same endurance test. The lifter on the left was made from our
USA material and Passed. The one on the right was made using overseas material and failed
very early. Which one do you want in your Performance Engine?

These Lifters have a Leak Down on the lower end
of the scale from 8 to 20 seconds. In the performance application these lifter will actually
“Bleed” down and result in an effective loss of valve lift and duration at lower RPMs. These
are also referred to as “Variable Duration” Lifters and will supply a better idle quality when
using a performance cam while still getting the benefit of the upper end power over a stock
cam. As the engine increases in RPM the Bleed down effect is reduced resulting in more duration and valve lift.

Having lifters with a much smaller Leak Down range will also balance all
of the cylinders to each other. Having one cylinder with lifters having a Leak Down of 80
seconds will react and produce a different power curve than the same cylinder with a 10
second Lifter.
