Risking your engine on a faulty Oil Pump? It’s time for a replacement.

We all know losing oil pressure can result in catastrophic damage to your engine. An oil pump is a lot cheaper and easier to install than a full rebuild kit, so why risk it? Replace your faulty Oil Pump with one from Highway and Heavy Parts.

You expect a lot from your rig. Keep it running cool, the way it was designed, with a premium aftermarket Oil Pump from HHP. While most believe aftermarket retailers sell cheap parts with no warranty or customer support, HHP is here to kick that stereotype to the curb. HHP sells Oil Pumps designed to surpass OE tolerances, with a 2-Year Parts and Labor Warranty, all at up to 50% off OEM prices. Top it off with support from HHP’s certified techs and service writers, and you’ve got the recipe for quality diesel repair, all the way from diagnosis to delivery. So, how’s that for an aftermarket part?

Need proof? Let’s talk Oil Pumps.


  • Want to keep your favorite rig in the family for years to come? We can help. A new Oil Pump will keep your engine cool and well lubricated for a million more miles.
  • Maximize your engine with a new Oil Pump that was manufactured to strict OEM specifications by experts in an ISO 9001:2015 certified facility.
  • Don't put your engine at risk. Replacing your Oil Pump will help other engine parts perform more smoothly and regulate oil pressure.
  • Want to save some coin? You bet. We offer our parts at equal or better quality compared to the OE, but at a much lower cost - and there's no core charge attached!
