What Makes the 3406E/C15 Turbo So Great

It doesn't matter where I get my turbo from, right? They're all the same.

Not quite.

When you're purchasing parts for your diesel engine, you want to know that you're getting the best possible quality components. That's where HHP comes in!

Our turbochargers are manufactured in a TS16949 management certification facility, so you know this ensures quality and consistency.

Each component is thoroughly inspected for fit and finish, before being built into the turbo. The turbine housing and center section are made of cast iron and the compressor housing is made of aluminum.  This will provide long lasting strength and durability.

When you install this turbo, you'll see increased power, efficiency, and performance in your CAT diesel engine. This is a true sign that these turbos are built to OE specifications. 

Better yet, all new turbochargers come with no core charges and a 12-month parts warranty. That's hard to beat when you're looking to upgrade your engine.


What's Causing Issues in my C15?

If you think you're having a problem with your C15 diesel engine turbocharger, you're probably wondering what caused it. 

With this turbo, there's a number of things that might be giving you problems, including:

  • Damaged housing
  • Carbon/debris damaging fins
  • Failed bearings
  • Air leak resulting in loss of pressure
  • Leaks in compressor or turbine side
  • Damaged compressor or turbine wheels

If you're experiencing low power, passing oil, or running hot, you might be having problems with your C15 turbochargers. As with any diesel engine problem, proper diagnosis is the key to correcting the issue. Otherwise, your new turbo could break the same way, costing you even more money.
