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 Unlimited Mileage 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.

  • Lower emissions, and soot saturation prevention? You get it all with Forged Steel Pistons, which are lightweight, high-strength, and provide a much longer life as they expand and contract less than traditional pistons.
  • Go the extra mile, or a million extra miles-with Piston Pins that are hardened and tempered for improved strength and wear resistance. Ever heard of the little engine that could? We bet it had these Piston Pins.
  • Keep oil where it needs to be with Oil Control Rings designed with precise tangential tension for maximum oil control.
  • Induction hardened cylinder liners for reduced bore wear.
  • Roll burnished flange radius for increased flange strength.
  • Trust the experts with a Rebuild Kit manufactured and assembled in an ISO 9001:2008 certified facility. Simply put, it's quality and consistency you can count on.
  • Automatic bore honing to control finish for fast break-in and oil control.
  • Profiled piston pin bore for piston pin joint durability.
  • Piston pins are hardened and tempered for improved strength and wear resistance.
  • Piston rings made from alloy cast iron or steel where required and coated on ring faces with wear resistant materials for extended wear characteristics.
  • Proudly made right here in the United States of 100% asbestos free material.
  • Unlike OEM this kit contains 100% new parts so you don't have to deal with cores.
  • Replacing the critical parts of your engine is important for engine life and function.
