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

My Samoyed loved this!
Size: Medium
My dog’s favorite thing. This is his 4th toy and he loves it. The quality is great and it lasts very long. Definitely worth every penny you spend. It keeps my samoyed engaged every morning and every night. There is no choke hazard, so all dogs can use it

Long lasting
Size: Medium
My dogs love these and they last pretty long. I take them away when they get very small so I think they’re pretty safe.

Meant for bigger dogs than mine
Size: Small
I bought this for my 10 month old pup who’s a VERY aggressive chewer. I’m going to say this is made for a large, older (than mine) dog. She tried to chew a couple times but eventually just walked away from it when I offered it to her and she had only made a few scratches in it. If you have that bigger dog that’s an aggressive chewer, it would be a good value for your money and will keep the engagement high for a long time with its heavy duty quality.

Finally… a dog chew that doesn’t become a homemade prison shank
Size: Medium
My dog has a real talent: turning every “tough chew” into a sharp, weaponized shard that could star in an episode of Locked Up: Canine Edition. But THIS chew? Absolute game changer. For the first time ever, I can relax—no splinters, no pointy edges, no fear he’s secretly crafting a shiv under the couch. Just happy, safe chewing that actually lasts longer than five minutes. It’s durable, it’s safe, it keeps him busy, and I no longer feel like I’m living with a furry little inmate planning an escape. Highly recommend if your dog chews like he’s got nothing but time.

Would buy again
Size: Small
Would have given 5 stars, but my dog was able to chew this down pretty quickly, so not the most durable. I do like that this is made with better material than other dog chews, so I would buy again.
