When it comes to Valve Locks, why risk your engine?

Don't let a small part turn into a major repair. We wouldn't risk putting sub-par parts into our engines, so why should you?

Combine this with up to 50% off OEM prices, an industry leading 2 Year Parts and Labor Warranty and technical expertise from HHP’s certified staff, and you’ve got a quality Valve Lock that will keep you running for another million miles.

Need a little extra proof? Let's talk shop.

  • At HHP, the OEM does not make the cut. Our parts are crafted to strict OEM specification which gives you proper fit and function.
  • You should always expect quality when buying diesel engine parts. You will receive a brand new valve lock that is manufactured and assembled in an ISO 9001:2015 certified facility. This ensures quality and consistency.
  • Don't break the bank for sub-par parts. All HHP parts have equal or better quality compared to OE at a much lower price.
