Is your Cylinder Block in it for the long haul?

We all know in order to get a million of miles out of your engine you need to keep your engine cool, well lubricated, and perform regular maintenance. Let one of these slip... and your rig is going to wind up in the shop with you stuck waiting for the repair.

It's no secret that diesel engine parts can cost an arm and a leg. That’s where HHP steps in; we offer premium aftermarket parts at up to 50% off OEM prices. While most believe aftermarket retailers sell cheap parts with zero warranty, packed in a beat-up box from who knows where, HHP is here to kick that stereotype to the curb. HHP provides Cylinder Blocks with additional engine cooling properties and a 1 Year Parts Warranty. How’s that for an aftermarket part?

Need a little extra proof? Let's talk Cylinder Blocks.
  • Know what you are getting when you shop at HHP! Our cylinder blocks were manufactured and assembled in an ISO 9001:2015 certified facility to ensure quality and consistency.
  • Rest easy knowing your cylinder block was built to strict OEM specifications for proper fitment and functionality in your engine.
  • Go the extra million miles with our cylinder block! We make sure our cylinder blocks were crafted with hard wearing materials for long lasting strength and durability.
  • Not sure what you need? Do you have a technical question? Our ASE certified technicians on staff can answer all of your technical questions.
  • Don't pay more when you don't have to! This part was made to equal or better quality compared to the OE at a fraction of the OE cost.
