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 Unlimited Mileage 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.

Don’t settle for sub-par parts. This Engine Kit was made to strict OEM specifications in an ISO 9001:2015 Certified Facility, ensuring quality and consistency.
Think you’re tough? The piston pins in this kit were hardened and tempered for improved strength and wear resistance, making your engine stronger than ever.
In addition, tri-metal construction rod and main bearings are included for durability. You can’t beat that.
You’ll want to “seal” this deal. We’ve made sure that the correct materials were used to ensure that the gaskets in this kit have excellent performance in functionality and sealability.
Want accuracy? You’ve got it. The pistons were CNC turned to precise tolerances and computer controlled piston machining was utilized to maintain proper clearances.
Bring your engine back to the glory days. A new Engine Kit will restore and extend the life of your engine for a million more miles.
Want to save some coin? We’ve got your back. This Engine Kit comes brand new with no core charge and is offered at equal or better quality compared to the OE – just at a lower price.
