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 a brand new rebuild kit? You got it! You’ll receive a rebuild kit manufactured and assembled in an ISO 9001:2008 certified facility. This ensures exceptional quality and consistency.
  • Plus, quality will meet or exceed the OE’s at a much lower price. Lower price, higher amount of cash in your wallet. That’s more bang for your buck!
  • Speaking of money, there is no core charge. But here’s the kicker, you get all new parts! Don’t let the word “Aftermarket” scare you away!
  • Bring your engine back to life with a brand new rebuild, it will restore your engine to optimal working condition and increase it’s longevity.
  • Give your engine a backbone with rod and main bearings for durability. They are crafted with a tri-metal material to ensure they last a million miles or more. 
  • Ever heard of the little engine that could? He probably had the piston pins included. They are hardened and tempered for improved strength and wear resistance to keep you on the road, not on the side of it.
  • Increased power and efficiency? You got it! The pistons included utilize complex combustion bowl geometry. You can’t beat that!
  • Also, these pistons are computer control machined to maintain proper clearances. If that isn’t enough, the pistons are also CNC turned to precise tolerances.
  • Proper fitment and functionality won’t be a problem because strict OE specifications are met, giving you the best of both. 
  • Leakage? Never heard of it. It is probably because the oil control rings included are designed with precise tangential tension for proper oil control. 
  • Let’s seal the deal. The sealing products included are all proudly USA made and they use 100% Asbestos-Free Material. To top it off, the correct materials are used for maximum sealing performance.
