Description

Think you know the truth about OE Rebuild Kits? We’d bet you’d be surprised.
If we tried to sell you used parts for your Rebuild, you’d call us crazy. But, if you’ve ever bought an OE Rebuild Kit, you may have unknowingly paid a premium for used parts! Replacing used parts with more used parts!?! That sure doesn’t sit right with us. How about you?

When it comes to engine parts, the aftermarket often gets a bad rep. The idea that the aftermarket retailers sell cheap parts with zero warranty, delivered in a beat-up box written in another language is just plain wrong. HHP is here to set the record straight. We only sell Rebuild Kits with new parts, zero core charges, and a 2-Year Parts and Labor Warranty. On top of only offering premium quality parts, we also make sure you save up to 50% off OEM prices. Now, doesn’t that sound more like the parts you should be installing in the biggest investment of your career?

Need a little extra proof? Let’s talk Rebuild Kits.

Want lasting quality and consistency? Refresh and extend the life of your engine with an all new overhaul rebuild kit manufactured and assembled in an ISO 9001:2015 certified facility.
Refresh your diesel with the right gaskets! O-rings are individually numbered to ensure correct identification along with all components of this gasket set being made of the correct materials giving them the advantage in functionality and sealibility for your engine.
Time to seal the deal! Stop leakage with American made sealing products composed of 100% asbestos-free material.
Get long lasting durability with rod and main bearings put together with tri-metal materials to help your rig go another million miles.
HHP wants to save you both time and money! Each component of this overhaul kit is made to OEM specifications and packaged into sub assemblies to give them proper fit, functionality, and easier installation in your rig.
Want OE quality without the OE price? You’ve got it! Shopping with HHP you with always be provided with quality that meets or exceeds the OE’s for a lower price tag.
Upgrade your pistons! Pistons are CNC turned and use computer controlled machining to maintain clearances within your cylinders.
Go farther for longer with piston pins are hardened and tempered for improved strength and wear resistance.
