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 and ultimate performance? This is your brand new inframe rebuild kit. It will extend the life of your engine and keep your rig up and running for another million miles.
  • Let HHP help you save money. You'll get equal or superior quality compared to the OE at a much lower price. Further, optimal fit and functionality are a given being that this kit is crafted to OEM specifications.
  • You'll fortify your engine with tri-metal connecting rods and main bearings. Also, cylinder liners are induction hardened to reduce bore wear. If that isn't enough, try these piston pins hardened and tempered for improved strength and wear resistance.
  • Plus, durability is this rebuild kit's middle name. Piston rings are coated on ring faces with wear resistant materials for extended wear characteristics. To top it off, this kit is manufactured and assembled in an ISO 9001:2008 certified facility, this ensures excellent quality and consistency.
  • A removable, integrated carbon scraper ring is featured that prevents carbon build-up, increased oil consumption, decreased oil filter flow and increased DPF regeneration. You can't beat that!
  • Leakage? Never heard of it. Proper materials are used in the making of the gaskets, this gives you excellent performance in functionality and sealability. The sealing products are USA made and use 100% asbestos-free material!
  • Keep the oil where it needs to be with oil control rings designed with precise tangential tension for proper oil control. Proper oil control is vital for the engine and it will keep you on the road, not on the side of it.
  • We aren't done. The pistons included are CNC turned to precise tolerances, and there is graphite skirt coating on the piston for improved seizure resistance. In addition, you'll get a multiple steel layer graphite composite head gasket with high temperature seals.
  • You can rest assured all new parts are included within this kit, and there is no core charge! There is no doubt you are getting a great deal!
