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.

  • You’ll receive a brand new rebuild kit that goes through a strict manufacturing and assembling process in an ISO 9001:2008 certified facility. This ensures great quality and consistency.
  • If you want to extend the life and bring your engine to good working condition, this is the rebuild kit for you. Plus, you’ll get rod and main bearings composed of a tri-metal material to ensure long lasting strength and durability.
  • Think you’re tough? These piston pins sure are. They are hardened and tempered for improved strength and wear resistance. Extreme conditions? Not a problem for these bad boys. 
  • Let’s talk sealing products. The products you will get are proudly USA made and use 100% Asbestos-Free Material. If that doesn’t get you salivating, the correct materials are used for maximum sealing performance.
  • It is important to keep your engine well lubricated, but who would want leakage? The oil control rings included are designed with precise tangential tension for proper oil control. You can’t beat that!
  • Are clearances and tolerances on your list? They should be. The pistons included are CNC turned to precise tolerances and computer control machined to maintain proper clearances. 
  • Adding onto that, pistons utilize complex combustion bowl geometry for unrelenting power and efficiency. 
  • Rebuilding an engine is a lengthy process. The time spent installing this rebuild kit will be reduced because kit components are packed in subassemblies by function. Also, the parts will fit and function properly due to strict OE specifications being met.
  • Want to save some money? We’ve got you covered. Quality meets or exceeds the OE’s at a fraction of the cost. To top it off, all new parts are included and there is no core charge. That’s more bang for your buck!
