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.

No smells!
Scent: Orange, Size: 30 Count (Pack of 1)
These work really well for us in our camper. Our tank holds around 40 gallons. After dumping the tank I drop one in the toilet and flush for about a minute to add water to the tank. Then. Everytime we use our camper in the summer (2 or 3 times a month) I drop in another tablet in the toilet and do the same thing. This has worked great and we never have had a problem with smell! The box usually lasts me a couple of years. Definitely recommend.

Product great. Delivery not so much.
Scent: Lavender, Size: 30 Count (Pack of 1)
Product works fine. But having it delivered by Amazon in just a brown bag caused the plastic container that holds the product all in the bag. This really need to be shipped in a box. Aleast I can use the product and will have to store it in a Rubber made container.

Our go-to for RV tank maintenance – reliable
Scent: Pine, Size: 10 Count (Pack of 1), Scent: Pine, Size: 10 Count (Pack of 1)
This has become our go-to brand for maintaining the tanks in our 5th wheel camper. We’ve used several products over time, but we keep coming back to this one because it’s dependable and does exactly what it’s supposed to do. The drop-ins are super easy to use—just toss one in and you’re set. We’ve had no issues with unpleasant odors while using these, even during longer trips, which makes a big difference when you’re living in close quarters. We trust this brand and their products, and it’s one of those items we make sure to always have stocked before heading out.

Not the best of scents for an RV Toilet Tank
Scent: Lavender, Size: 30 Count (Pack of 1)
I don't know why I thought the scent of lavender would be great for my black water holding tank, but it's not. I'm sorry to say that I will have to return it. There's 30 Camco toilet 🚽 treatment packets in this container. All you have to do is just drop one of these packets into the toilet and flush it down into the holding tank. I am not saying that this product is not good; I'm saying that I will have to exchange it for a different scent. I won't know until I try a different scent, because I might be allergic to Camco's RV Toilet Treatment Drop-ins. The lavender scent put out such a bad smell, I couldn't breathe all night last night. I had to keep filling up my tank, waiting for awhile, and then dumping it all out. I had to keep doing that till the bad smell went away. So I'm gonna give Camco another chance, and try a different scent, and just go from there. I should have known better than to use a toilet treatment that had a perfume scent. I'm allergic to fragrant's, I have to use fragrance free laundry soap.
