FAQ
What is the difference between rocker arms and roller rockers?
- Rocker arms are basic engine components, while roller rockers have built-in rollers for reduced friction. Roller rockers often enhance performance and are ideal for high-performance applications.
What are the different types of rocker arm shafts?
- Rocker arm shafts vary by material and design. Common types include standard stamped steel, aluminum, and specialty shafts. Choose based on your engine's needs for durability and performance.
Is a loose rocker arm bad?
- Yes, a loose rocker arm can lead to poor valve performance and engine issues. Regular inspection and proper adjustment are crucial to prevent damage and ensure optimal engine function.
What does upgrading rocker arms do?
- Upgrading rocker arms, especially with high-performance options like the JEGS 20198 rocker arm shaft assembly, can enhance valvetrain stability, reduce friction, and contribute to overall engine efficiency and power.

A must have for a rebuilt or aging FE engine
I had my 390 rebuilt and the shop never suggested to replace my rockers or push rods at the time so they installed the 50 yr old stock set the ticking drove me nuts . With valve cover off I could pull the rocker arm up and down against the push rod slightly and found that the tick tick tick was coming from the play between the push rod and rocker arm .
Before I installed the jegs set with new pushrods I mic gauged the old pushrods and the foot or contact section where the rocker arm and pushrod contact , compared to the new set they were as much as 3mm worn out !!!!! On the rocker and 2 mm on the pushrod ouch. I had a blow by issue on the #8 cylinder that fouled the spark plug and gave me a rough idle that I thought was a vacuum leak , it even would ruin my vacuum pod on the vacuum advance diaphragm I went through 2 of them from the oil residue .
After installing the jegs set there was no play at all in the rocker and pushrod and immediately the blow by issue was gone ..Why ? Because the pushrod and rocker were so worn out it wasn't pushing down on the exhaust lifter side and trapping exhaust in the cylinder at least that's my opinion ran better from day one better idle the ticking was 80% quieter awesome .

Look just like OEM rocker arm assemblies
I bought these for the 390 FE in my 1974 F100. The original rockers were worn out and filthy. These are constructed exactly the same as the originals and appear to be very well made.

Looks good so far.
I haven't run these yet but everything looks just like the originals and I test fit them on the cylinder heads and everything lines up good.

look good
These look like a well made part. I have only ran the engine enough to break it in as the car is not finished. So far so good. I am giving 4 stars as long term durability is yet unknown,

JEGS (JUNK) Rocker Arm Assembly for Ford FE
Product is junk. Rocker arms do not sit evenly spaced over the valve stems. Some are aligned evenly, some cover only 90% of the valve stem. 1st time I used these and 1 rocker walked off of the valve stem causing the spring to come apart. Luckily my new valve seals kept the valve from dropping onto the piston and bending the brand new valve. Also lucky to not lose the keeper into the motor. JEGS refuses to do anything other than offer to sell me more expensive options, and won't even pay shipping for me to send these back. This is the last purchase I'll ever make from this joke of a company....its no wonder Speedway and Summit are so popular as I've never had an issue like this with either of them.

Will this fit a Ford 370?
