PAYMENT

Unfortunately, Ebay deleted all my previous user information when they got their new computer system because I was inactive for around 15 years and this included a perfect feedback for over $200,000.00 worth of items, therefore, I had to sign up as a "new" user which means that Paypal will hold any funds I receive for 21 days until I sell/buy 35 items or more . If you do not want to wait 21 days to get your parts, you must use Paypals "Friends And Family" payment program or send a Money Order etc.


These rocker arms are one of the the best kept secrets in the FE world . They are original Ford Power Parts Stage 4 rocker arms which were designed by FE guru Ron Miller and came with a Lifetime Warranty . Precision Oil Pumps is the new manufacturer.

These are CNC machined from 7075 T6 aluminum which is extremely expensive and around twice as strong as the 6061 T6 aluminum some other name brand arms are made out of and is around 30% stronger than the 2024 T3 aluminum the extremely expensive D Series Harland Sharp arms are made out of and can withstand up to 700 lbs of valve spring pressure.

They are 1.76 ratio.

Each rocker has 2 Aircraft grade, high nickel content bronze bushings which will last much longer than the "budget" bronze bushings other manufacturers use.

They also have massive 7/16" diameter Jessel type inverted cup hardened lash adjusters with ARP 12 point nuts . The inverted cup adjusters allow the use of conventional ball or radiused end style pushrods on the rocker end instead of the stock cup type design.

The lash adjusters are also offset in the rockers . 8 of them are offset .075" to the left and 8 are offset .075" to the right to help prevent the pushrods from rubbing the Intake Manifold which is a notorious problem on FE engines with high lift cams and/or larger than stock push rods.

The bushings have a 1/16" wide space between them . This creates a 360 degree oil groove around the entire rocker shaft for improved oiling which further reduces wear . The oil groove also supplies pressurized oil to the push rod tip through the ingenious lash adjuster design and also to the roller.

The rollers are made from heat treated 8740 Chromoly, and the pins are tool steel with retaining clips instead of being a press fit like most other roller rocker pins are which can loosen in the rocker if high spring pressures and/or solid lift cams are used.

The lash adjusters are also offset . 8 of them are offset 075" to the left and 8 are offset .075" to the right to help prevent the pushrods from rubbing the Intake Manifold which is a notorious problem on FE engines with high lift cams and/or larger than stock push rods.

The rockers will clear stock valve covers.
