The Fleece Performance Freedom Series HD Cylinder Head for the 6.0L PowerStroke - 18mm Dowel is built to OEM-or-better standards for diesel truck owners who want a no-compromise upgrade. Engineered, manufactured, and supported by Fleece - the diesel performance specialists.

Features
  • Brand-new, higher tensile strength casting
  • Race-proven formula with hardened, oversized press-in valve seats provides maximum durability and longevity
  • Fleece Performance exclusive single-piece O-ring design ensures complete combustion sealing vs. traditional stainless wire that must be seamed.
  • New valvetrain including Stainless Steel/Inconel alloy valves, springs, retainers, and keepers
  • No core charge or core to return.
  • Improved casting. This isn't your run of the mill, rinse and repeat OE casting. Engineered from the ground up with years of testing and development - our higher tensile strength alloy castings incorporate increased wall thickness and additional material where it counts, providing for a more durable and longer lasting cylinder head.
  • Extreme duty valve seats. Race proven and stronger than OEM - our American made valve seats provide for longevity and stability in the cylinder head. Produced from a tungsten alloy for increased hardness, these seats deliver a substantially higher wear resistance vs. a stock replacement seat.
  • Single piece O-ring. Our 6.0L cylinder head is the only cylinder head available with a single piece hoop style O-ring. Our single piece O-ring ensures complete sealing of combustion vs. traditional stainless wire that has a seam.
  • All 20mm dowel heads are configured for 2-bolt rocker box configurations.
  • Fleece Performance recommends the use of 6.4L pushrods (Ford Part No. 8C3Z-6565-B) when installing these cylinder heads. 6.4L pushrods are 0.050 inch shorter in length vs. a 6.0L pushrod and will accommodate the tolerance stack ups that can be encountered with a replacement cylinder head.
  • Head gasket not included. We recommend the use of Ford Part No.KZ3Z-6051-B.
  • Fits: 2003-2007 Ford F250/2003-2007 Ford F350/2003-2007 Ford F450/2003-2007 Ford F550

Great socks, watch out for bad seller
Number of Items: 6, Color: Black (6-pairs), Size: Medium
The socks are great, comfy, padded where you want it. I used these for work socks; I have a blend of corporate desk life and maintenance work. I like the low cut so my shoes don't rub the back of my ankle but not so high that socks always fall down. Great for running and sports as well. Been using these for years. Buyer beware though of the particular seller Liegnitz Group: They were late shipping, sent me the wrong socks so I sent for a return and they send me the right ones. My return got delivered back to them but they did not process it and did not send out any new ones. They cancelled my order and acted like I got the right ones all along. Buy from a different retailer.

Comfortable with perfect fit
Number of Items: 6, Color: White (6-pairs), Size: Medium
I have had these socks for a few weeks now and wear them when running. I have small feet at a men's size 7 and they fit perfectly. Most men's socks are to big for my feet. They are pretty thin but well made and have good cushion. I recommend these for anyone that likes ankle socks for athletic activities.
