Don?t risk your your engine to some no-name, sub-par Crankshaft.

There?s no throwing a bandage on a bad crankshaft. In fact, trying to limp along is only going to cause more damage. Keep your rig running strong for another million miles- without emptying your pockets- with a Crankshaft from HHP.

Forget choosing between quality and price. HHP only offers premium aftermarket parts at up to 50% off OEM prices. While most believe aftermarket retailers sell cheap parts with zero warranty, HHP is here to kick that stereotype to the curb. HHP provides Crankshafts with exceptional quality and a 2-Year Parts and Labor Warranty. How?s that for an aftermarket part?

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

  • You will have longer engine life with this brand new crankshaft because it is crafted with long lasting strength and durability. You can't beat that!
  • Also, ditching your old crankshaft and replacing it with a new one can provide a smoother ride. Plus, this new crank has no core charge.
  • Proper fitment and function within your engine is guaranteed with this crankshaft because it is crafted to strict OE specifications. If that isn't enough, you'll get equal or better quality compared to the OE at a much lower price! Imagine the money you'll save!
  • To top it off, this crank is manufactured and assembled in an ISO 9001:2008 certified facility that ensures top-notch quality and consistency of parts!
