    Hot Rods already makes great crankshafts, so what makes the Hot Rods Complete Crankshaft Assembly Heavy Duty ones so special? Well, with modifications and power increases, the stress on engine components also increases. With this in mind, Hot Rods has designed their heavy duty crankshafts to thrive while taking extra abuse. They’ve done this by adding material in high-stress areas of the connecting rod forging to create a much stronger rod that resists deformation, keeps bearings in better condition, and outlasts OEM parts. In addition to this, a bronze bushing is added inside the wrist pin bore to reduce wrist pin galling and improve loading resistance. These advancements are in addition to the features of Hot Rods standard crankshafts and make the Heavy Duty Crankshafts perfect for big bores, high compression engines, turbos, or anything else.

    Specs:
  • Replacement heavy duty crankshaft assembly
  • Fits just like a stock crankshaft
  • Pre-assembled with connecting rods, top-end bearings, and crankshaft webs
  • Extra-strength connecting rod forgings increase material in high stress areas
  • Bronze bushing in wrist pin bore reduces galling and increases loading resistance
  • Trued and tuned to OEM specs
  • Meet or surpass OEM criteria
  • Copper plated rod and webbing surfaces
  • Heat treated and case hardened
  • Made in Urbandale, Iowa USA

Perfect Fit
After completing a top end I found out that my connecting rod bearing had seized so I bought this crankshaft. It dropped in perfectly and my bike runs great.

Excellent Part
This crank now has 75hrs on it. Runs like the day it was installed. Just installed a 3rd piston since the crank install. Could not be happier with this product. Installed the hot rods main bearings & seals as well when the crank went in. Im also running 13.5 comp ratio pistons. Will easily go another 75+ hrs. Every bit a durable as stock & maybe more so.

Great foundation for a CRF250R
Utilized this crankshaft in a rebuild of a CRF250R, and discovered this well worth the price. Highly Recommend

Hot Rods Cranks
I have put hot rods cranks in my 2 strokes as well as my 4 strokes and like them, except the one in my yz450f cracked in half in about 200 hours.
