Crankshaft kits include a crankshaft, an upper bearing, premium quality main bearings and a complete set of lower seals, including all the gaskets needed to do the job.

• Only one part number to store and order
• Crankshafts are factory-assembled and precision-ground to OEM specifications.
• Wiseco''s double-forged connecting rods maintain superior dimensional consistency thanks to improved grain circulation.
• Shot-blasting eliminates residual stresses and smoothes the forging surfaces of connecting rods.
  Corrosion-resistant surface treatment
• The upper and lower connecting rod bores are case-hardened to 58-62 RC to optimize the bearing running surface.
• Crankshaft bearing radial clearance is optimized for maximum performance.
• Precision lapping ensures an ultra-round bearing surface
• Precision-engineered lubrication slots maximize rod resistance and bearing life.
• The small, double-drilled ends provide the piston pin with additional lubrication and cooling, reducing distortion of the upper part due to piston heat transfer.
• Phosphorescent thrust washers in silver-coated bronze, with dimpled design to increase oil retention and reduce friction between the rod and washer interface.
• Crankpin bearings are manufactured from the highest quality hot-rolled steel, case-hardened to 58-62 RC.
• Needle cage bearings ensure the best possible rpm.
• Precision-machined crank wings
• Wiseco complete seal kits are made from premium materials for maximum sealing and reliability; all bearings are OEM quality for reliability and performance.
• Connecting rod kits include connecting rod, crank pin, crank pin bearing, connecting rod head bearing and thrust washers.
