When it comes to Bolts, 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?

HHP only sells Bolts that are manufactured in a state of the art facility using top of the line machining and measuring equipment to ensure each part is manufactured to OEM specifications. Combine this with up to 50% off OEM prices, an industry leading 2-year warranty and technical expertise from HHP’s certified staff, and you’ve got a quality Bolt that will keep you running for another million miles.

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

  • Replace your worn out bolt with a brand new one built to OEM specifications.
  • A brand new bolt will keep your engine secure to help you go a million more miles!
  • We ensure you'll receive quality because this part is manufactured and assembled in an ISO 9001: 2008 certified facility.
  • To top it off, you don't have to overpay for a bolt. At HHP you'll get equal or better quality compared to the OEM at a much lower price.
