The Johnson Lifters® name has been known within the industry for over 50 years. In 1954 Johnson began producing millions of lifters for General Motors and thus laid the foundation for a credible name in the market. Johnson shifted their sights to the aftermarket business where cost isn’t everything and component integrity is! Their goal remains to produce the best lifter for the weekend warriors, street rods, and race enthusiasts.
Features include:
- Cold forged steel body heat treated for exceptional wear resistance.
- Precision ground needle roller bearing with high chromium steel axle for long life and minimal friction.
- Cold forged extra long piston, precision ground and fitted for controlled leak down and pump up.
- High flow disc style quick reacting check valve for better reaction at higher RPM.
- Precision oil metering assuring proper oiling to the rocker arms without sacrificing oil pressure.
- Cold Start noise is commonly attributed to two main factors: High valve spring pressure, The high leak (bleed) down rate of the lifter (SLR lifters are actually a positive here)
- Johnson lifters have the largest inlet from low pressure (engine oil pressure) to high pressure (holds the load via the pushrod to from the rocker arm). Johnson uses the largest disc style check valve in the industry.
- Cold forged 1018 steel blanks CNC’d to final dimensions. Heat treated for exceptional wear resistance. Chosen over 8620 for roller pocket strength. The grain structure from forging increases the durability and dimensional repeatability in that area, which allows for an encapsulated roller versus an open fork design. The encapsulated rollers when used with standard GM diameter lifter will take higher spring loads than an open fork design.
Recommended Lifter Installation:
1. Inspect the lifters for any signs of damage to the lifter body or wheel.
2. Verify the rollers spin without any binding.
3. Wipe down the lifter body with a lint free rag.
4. Coat the outside of the lifter with engine oil (not recommended to soak)
5. Debris entering a lifter is the main cause of failure. Clean the top end of the engine to ensure no foreign debris can enter the lifters upon startup.
6. Inspect the Rocker Arms, Pushrods Ends, and Valve Tips for excessive wear. Replace as necessary.
7. Install lifters and set the lifter preload to the recommended specifications.
8. Change oil/filter after 50 miles to remove any debris that may have been missed during assembly.
