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 where you need to go with a brand new Overhaul Rebuild Kit to restore and lengthen the life of your engine. 
  • Maximize your engine with a brand new overhaul rebuild kit from HHP! All brand new parts are manufactured and assembled in an ISO 9001:2015 certified facility ensuring proper fitment and function. Since these are all new parts, there is no core charge. Giving you more money in the bank!
  • Keep your engine properly lubricated by having the correct gasket materials in use to confirm top-notch performance in functionality and sealability.
  • Alongside your gaskets, American made sealing products from 100% asbestos-free material make certain your engine has long lasting leak free durability
  • Why sacrifice quality if you don’t have to? For durability, connecting rod and main bearings are made with tri-metal materials. 
  • We want to help you keep oil where it needs to be. Oil control rings are designed with precise tangential tension to give your engine the proper oil control it requires.
  • Stop paying ridiculous OE prices! Put the OE to shame with equal, if not better quality parts made to OEM specifications, at a much lower price compared to the OE! 
  • Get the most out of your pistons! These pistons are CNC turned to precise tolerances and use computer controlled machining to maintain proper clearances
  • To top it off, piston pins are hardened and tempered to provide maximum strength and wear resistance within your cylinders.
  • Time is money. Along with fast delivery, overhaul kits are packed in subassemblies by function, making for an easy installation and to get you back up and running quicker.
