Ford 1985 Up SBF Drop-In Slow Bleed Hydraulic Roller Lifters
These fit all Ford 302-351W Hydraulic Roller Blocks that use the OEM Dog-Bone Style Lifter Tray Hold Down or the Ford Racing M-6253-A50 ROLLER CAM CONVERSION KIT.
These are a superior choice to the Ford Racing M-6500-R302 Mustang 1985-1995 Hydraulic Roller Cam Lifters or the Ford Racing M-6500-R302H HIGH PERFORMANCE HYDRAULIC ROLLER CAM LIFTERS that utilize the weaker Fork Style lifter body. The Hy-Lift Johnson Forged Body offers a full 360° of roller axle support that will not spread under high spring loads.
Installation Notes: These Lifters only require .025-.040" Pre-Load. Adjustable Rocker Arms and Accurate Push Rod Lengths Are Highly Recommended
A-2268SE: OEM replacement that has a slow leak down to handle heavier valve spring loads and RPM’s plus includes our Direct Shot bearing lubrication.
“S” or Slow Design:
In a performance application these lifters will actually act like a mechanical lifter with very little effective loss of valve lift or duration at any RPM. These parts also have a positive retainer instead of the OEM wire clip design. These Lifters these have a much smaller Leak Down range that will also balance all of the cylinders to each other. These lifters are very hard to produce because the TOTAL clearance between the I.D. of the Body and the Piston assembly is reduced to less than 0.000120” or 1/30 of a human hair.
Direct Shot Roller Lifters:(patented)
Hy-Lift Johnson introduces Direct Shot (TM)Bearing Oil injection system as an option to all of our roller Lifters, Identified by an “E” after the part number like A-2268SE. Our system utilizes a proprietary oil band system that prevents debris from clogging up the oil supply hole. Our Oil Supply hole is located down from the Engine oil supply gallery where debris travels. This prevents pieces of debris from clogging up the 0.012” diameter oil supply hole. Other designs supply oil from the oil band area which is exposed to debris that might be in the oil system. Once the oil hole is clogged the benefits of this type of system are rendered useless. We also provide holes to each end of the bearing for extra reliability. Extreme engine testing has shown that our
system has improved durability by as much as 300%.
OEM Design Roller Lifters:
Hy-Lift Johnson Inc. manufactures millions of roller lifters every year. Every lifter undergoes stringent quality requirements starting with the initial material through our final assembly. Since we produce so many lifters we are able to streamline our manufacturing to capitalize on efficiency of large scale production. All of our Roller Lifter bodies are produced from forged steel blanks. The tooling needed to produce our forgings is very expensive, but the forging process produces a superior part and also save us time machining. The roller pocket is forged into the body as is most of the internal area. This reduces our manufacturing cost significantly while supplying our customer with a superior product. The roller bearing is completely supported unlike some competitors that use a fork design because they machine their parts from a solid bar.
Hy-Lift Johnson Inc:
We have been manufacturing lifters in Muskegon Michigan USA for over 88 years and some of our employees have been with us for over 50 of those years. We do all of the Design, Engineering, Manufacturing, Assembly and Testing in-house so we can control the quality of our product 100% and you can have 100% confidence in it. Our company is dedicated to the manufacturing of the best lifters available in our 167,000-sf facility in Muskegon. Our employees operate super precision grinding equipment as well as multi-million dollar assembly machines that perform 20 quality checks on every hydraulic lifter. We also have a brand new 255,000-sf facility in Brooksville FL that we are expanding our new manufacturing too instead of following the acceptable practice of going overseas to save a dollar or less.
