Product Features:

One part number contains everything you need for your Bottom End Rebuild. All Wiseco crankshafts are supplied complete with main bearings and a bottom end gasket kit. Now, by ordering a single part number, you get everything you need for a crank swap in one box. Every Wiseco crank has been rigorously engineering and field tested to ensure it exceeds the highest quality standards.

  • Crankshafts are factory assembled and precision trued to OEM specifications.
  • Double forged Wiseco connecting rods maintain superior dimensional consistency through improved grain flow.
  • Shot peening eliminates residual stresses and smoothly blends the rod forging surfaces.
  • Corrosion-resistant surface treatment.
  • Top and bottom end rod bores case hardened to 58-62 RC to optimize bearing running surface.
  • Precision honing ensures ultra round bearing surface.
  • Precision engineered oiling slots maximize rod strength and bearing life.
