Description

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 Parts and Labor 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.

  • Want unrelenting power? You’ll receive a new overhaul kit with all brand new parts made to OEM specifications helping fortify and restore your engine.
  • Don’t settle for sub-par parts, the piston pins included are hardened and tempered for improved strength and wear resistance.
  • To help you keep oil stay where it needs to, the oil control rings are designed with precise tangential tension to give your engine the proper oil control it requires.
  • Get back up and running in no time. The components of your overhaul kit are packed in sub-assemblies by function, making installation for you simple. 
  • We emphasize quality here at HHP. We make sure your kit is manufactured and assembled in an ISO 9001:2008 certified facility. Simply put it’s quality and consistency you can count on.
  • This kit is proudly manufactured in the USA and all sealing products are made with 100% asbestos free material. 
  • Go a few extra miles, or another million miles with computer controlled piston machining to maintain proper clearances
  • Why sacrifice quality if you don’t have to? Receive a new overhaul rebuild kit with equal or better quality compared to the OE, but at a much lower price
  • Speaking of a much lower price, all rebuild kits do not have a core charge. It doesn’t get much better than that! 
  • Help keep your engine sturdy over time. OEM gasket materials are used throughout your rebuild kit for leak free durability, keeping your engine running for optimal performance.
