Think you know the truth about OE Engine Overhaul Kits? We'd bet you'd be surprised.

If we tried to sell you used parts for your Overhaul, you’d call us crazy. But, if you’ve ever bought an OE Engine Overhaul 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, 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 Overhaul Kits with new parts and zero core charges. 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.
