Think you know the truth about Aftermarket Rebuild Kits? We'd bet you'd be surprised.

It’s no secret, rebuilding your rig is one of the most labor (and wallet) intensive repairs out there. Sure, you want your engine to last another million miles but you also want the best price; so what should you choose- OEM or Aftermarket?

When it comes to engine parts, the aftermarket often gets a bad rep. The idea that aftermarket retailers sell cheap parts with zero warranty, delivered in a beat-up box written in another language couldn't be further from the truth. 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. So, when it comes to your rebuild, what's left to want?

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

  • Count on quality with Oil Control Rings designed with precise tangential tension for proper control, 100% Asbestos-Free Sealing Materials, and Tri-Metal Main and Rod Bearings.

  • Simplify the repair process with Premium Gasket Materials that are organized into sets for easy assembly.

  • Choose quality you can count on, as every rebuild kit is assembled in an ISO 9001:2008 Certified Facility.
