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.

  • Get a brand new rebuild that will restore your engine to great working condition and extend the life of it. You can’t beat that!
  • Want durability? You got it! Rod and main bearings are constructed with a Tri-Metal material for longevity. These bad boys will keep you on the road and not on the side of it. 
  • 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.
  • Don’t settle for sub-par parts! Quality will meet or exceed the OE’s at a much lower price. Don’t settle for ridiculous OE prices when you can have more cash in your wallet
  • Trust the experts with a Rebuild Kit manufactured and assembled in an ISO 9001:2008 certified facility. You’ll get exceptional quality paired with consistency.
  • Adding to the savings, all new parts are included and there is no core charge. It’s a win-win situation here at HHP. 
  • Also, fitment and functionality will not be a problem because strict OE specifications are met giving you the best of both. Don’t let the word “Aftermarket” turn you away!
  • Keep oil where it needs to be with Oil Control Rings designed with precise tangential tension for maximum oil control. Your engine will be properly lubricated and ready to go when you need it. Adding onto that, the sealing products included are proudly USA made and are composed of 100% Asbestos-Free Material!
  • You’ll sleep soundly knowing the pistons included are CNC turned to precise tolerances making your life easier. To top it off, they are built with long lasting strength and durability for ultimate performance. 
  • Additionally, computer controlled piston machining is used to maintain proper clearances, giving you peace of mind.
  • Let’s seal the deal. The gaskets included are used with proper materials for maximum sealing performance, keeping your fluids where they need to be. It simply doesn’t get better than that!
