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.
Trust the experts with a kit manufactured and assembled in an ISO 9001:2008 certified facility. In other words, it’s quality and consistency you have confidence in.
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.
Get the most out of your cylinders! Maximize power with CNC turned pistons and computer controlled machining to maintain proper clearances.
To sweeten the deal, piston pins are hardened and tempered in order to improve strength and wear resistance. You can’t beat it!
Want durability? You got it! Rod and main bearings are constructed with a tri-metal material for longevity.
Be confident you are maintaining proper oil pressure with oil control rings designed with precise tangential tension.
Your rebuild kit consists of all brand new components made to OEM specifications. These parts will fit and operate correctly in your engine and have equal or better quality compared to the OE for a much lower price and no core charge!
Not only will HHP save you money, we will save you time! For a simpler installation, overhaul kits are packed into sub-assemblies by function.
