Cummins ISX Engine Rebuild Kits from HHP

Cummins Engine | Highway & Heavy Parts

Here at HHP, we’re pretty proud of the rebuild kits we offer. So, we’re going to use this article to brag a little bit about the rebuild kits we have to fit various Cummins ISX engines.

 

Types of Engine Rebuild Kits

Not all rebuilds are alike, and that’s why we won’t offer a one-size-fits-all kit. Customers can choose from three different kit levels that fit the ISX, depending on their needs. Some of the more popular options include re-ring kits and inframe rebuild kits.

Re-Ring Kits

If your pistons are still in great shape, re-rings kits are a great option. These kits will have all of the standard rebuild kit components, except for pistons. They will still come with piston rings, as you should always replace piston rings when you work inside of the cylinders. The kit is called “re-ring” because you’re putting new piston rings on your current pistons. Installing a re-ring kit can easily be done while keeping the block in the vehicle frame.

Inframe Rebuild Kits

Inframe kits are the most common rebuild kits bought. One of our best selling rebuild kits for an ISX engine is an inframe rebuild kit.

You'd want an inframe kit for a standard rebuild, one where you are not pulling the block out of the vehicle frame. It has everything needed to overhaul your engine, except a lower engine gasket set.

Features of the Engine Rebuild Kits for Cummins ISX

We offer the current generation of piston design. The pistons are forged steel, rather than cast, giving them superior strength to handle whatever your engine throws at them. These forged pistons also have an improved skirt profile and oil plate retention. The piston rings also feature a coating that improves performance and oil control.

The cylinder liners of the ISX kits HHP offers feature an induction-hardened plateau honed finish. This means you get the cylinder liners at the optimum hone, and the break-in after rebuild should result in fewer metal particles getting into your oil. This also means you should start off your newly-rebuilt engine with better sealing capability.

We also offer Anti-Polishing Ring (APR) Liners. It's important to note that these liners are not interchangeable with previous cylinder liner types, and apply to ISX15 Tier 4 XPI, single cam engine models. These liners feature a removable, integrated carbon scraper ring at the top of the cylinder liner. This ring prevents carbon from coming into contact with the cylinder walls. When the piston builds up with carbon, carbon contacts the cylinder walls, which polishes the cylinder liner. Polished cylinder liners lead to oil consumption, DPF regeneration, and decreased oil filter flow.

We're here to help make sure you get the right rebuild kit for your ISX engine—or any diesel engine part you might need. Call our certified techs at (844) 215-3406, or you can request a quote online.
