Looking to get fire rings in your 24 Valve Cummins? Industrial Injection's Premium Stock Plus Cylinder Head With Fire Rings is a great way to get the fire rings seal that allows your engine to handle the higher pressures your combustion chamber can produce when you add higher performance injectors or fuel systems. No matter what you use your truck for, fire rings are a great way to add strength and longevity into your engine so you know it will last for 100k miles and beyond.

NOTE: Fire Ring Gasket sold separately. Installation of a fire ring gasket requires high yield head studs to ensure proper seat of the head to the cylinder block.

The Industrial Injection Premium Stock Plus Fire-Ring Cylinder Head is designed to provide increased durability, improved combustion sealing, and dependable performance for 5.9L 24-valve Cummins engines. Built for diesel enthusiasts who demand more strength than a factory head, this upgraded cylinder head is ideal for towing, daily driving, and moderate performance builds.

Featuring machined fire-ring grooves and upgraded internal components, this head helps your Cummins engine handle higher cylinder pressures while maintaining reliable operation. Each head is precision-machined and assembled by Industrial Injection, a trusted manufacturer of high-performance diesel engine components.

Fire-Ring Ready for Improved Combustion Sealing

This 5.9 Cummins 24-valve cylinder head includes radius-cut fire ring grooves designed to work with a fire-ring head gasket system. Fire rings provide a stronger combustion seal than standard gaskets alone, helping prevent head gasket failure in engines running higher boost levels or increased fueling.

By improving the seal between the cylinder head and engine block, this design helps support increased cylinder pressure and enhanced engine reliability.

Premium Components and Machining

  • Custom Performance Stainless Steel Nitride Coated Valves- Improved resistance to heat and wear in demanding diesel applications.
  • Premium Oversized High-Temperature Alloy Valve Seats- Higher press-in value for secure seating under extreme combustion temperatures.
  • Diamond Honed High-Strength Alloy Valve Guides- Precision machining ensures proper valve alignment and long service life.
  • Radius-Cut Fire Ring Grooves- Designed for fire-ring gasket setups to help contain high cylinder pressures.

These upgraded components help provide improved durability compared to factory cylinder heads while maintaining smooth engine operation.

Designed for Street, Tow, and Performance Builds

The Premium Stock Plus Cummins cylinder head offers the perfect balance of factory reliability and performance-oriented upgrades. It is well suited for trucks that are used for:

  • Heavy towing and hauling
  • Daily driving diesel trucks
  • Engine rebuilds and restorations
  • Mild to moderate performance upgrades

The upgraded design helps ensure your 5.9L Cummins engine can withstand demanding operating conditions while maintaining dependable power and efficiency.

Terrifying jaw strength..
Color: Green, Size: Medium(30-55 lbs)
Have 2 Corgi and it scares me that they make this thing squeak. The bite pressure they have now from working out jaw to squeak this like it's nothing. Didn't expect our smaller corgi to be able to squeak this couldn't at first now she just goes ham on it like it's no big deal.

Very sturdy for an aggressive chewer
Color: Green, Size: Large(50-90 lbs)
I was so surprised that this has lasted so long for my Black lab, who is an aggressive chewer. It is his all-time favorite toy. He chews it many times every day and the squeaker still works!

I FINALLY GOT AN INDESTRUCTIBLE TOY!!! Yes!
Color: Green, Size: Large(50-90 lbs), Color: Green, Size: Large(50-90 lbs)
This one is TRULY indestructible! I’ve been purchasing one after another trying to find something that she cannot break in 5 mins. Everything I’ve ordered (until this one) has been SHREDDED in 3-10 minutes! It’s TRUE RUBBER! I’m so happy with my purchase! See the picture below- we’ve had it for a couple months now and she has barely chewed off just a few small nubs! Which she’s proud of 😆 If you truly want a challenge for your CRAZY DOG- you will love this squeaker!

Rough and tough chew toy
Color: Azure, Size: Large(50-90 lbs)
This is a thick and heavy duty toy to stand up to medium to large dogs who are heavy chewers. And the rough textures really encourages my dog and it is the perfect size to throw and play fetch. Very sturdy…I bought around Christmas and it’s almost may and she hasn’t destroyed it yet!!!

This keeps my dog busy. He has a blast with it. It is a little bit big for his mouth, but he still seems to have fun with it. My dog is German Shepherd and Australian Shepherd.
