The foundation of any bottom-end rebuild is a solid forged crankshaft assembly, which provides strength and reliability that surpasses any cast part by far. Due to their lightweight, forged crankshafts have more compact dimensions and better dampening, they rev higher and run smoother than their cast counterparts.
This part of the engine has a huge amount of stress due to the twisting and bending that happens 1000's of times a minute so you don't want to risk an inferior product that could ruin your motor. Wiseco engineers have designed their crankshafts to meet or exceed OEM tolerances giving you the best base for your bottom end.
Wiseco powersports crankshafts feature a double forged connecting rod made from dedicated forgings. The rods maintain superior strength, durability, and dimensional consistency through improved grain flow. Shot peening eliminates residual stress and oil slots are located to maximize lower rod oiling and extend the bearings life.
Coated bronze thrust washers have a dimpled design to increase oil retention and reduces stress between the connecting rod, washer, and crank web. Double-drilled small ends provide the piston pin with extra lubrication and cooling, reducing top-end distortion due to thermal transfer from the piston.
Wiseco has designed these crankshafts and connecting rods to work together with our pistons to provide the smoothest rotating assembly possible. Having a complete bottom end that is made of 100% forged material will give you the piece of mind that your motor will be able to withstand any abuse within reason.
Both professional racers as well as weekend riders choose these reliable solid kits to reduce any failure and take advantage of their machine's horsepower and the immediate torque that a light weight bottom end can deliver.
-Each kit contains everything you need to complete your rebuild; crankshaft and connecting rod, all applicable bearings, and complete bottom end gasket kit made to meet or exceed OEM.
-Wiseco connecting rods are double forged from a dedicated forging and feature shot peening, oil slots, and coated bronze thrust washers.
-Bottom end gasket kits are made from premium materials, exceeding OEM standards, to provide exceptional seal between meeting surfaces.
-Main bearings are manufactured to the highest quality standards. Each is case hardened for maximum life and smooth operation at a high RPM.
-Corrosion resistant surface treatment to prevent corrosion and pitting over long term use or storage. This will add to the life as well the strength of the assembly.
-Top end of rod is bushed for oil retention and eliminates pin galling. The bottom end rod bores are case hardened to 58-62 RC to optimize bearing running surface.
-The crank pin bearings are manufactured from the highest quality, hot rolled steel case hardened to 58-62 RC to extend the lifetime of the assembly.
-Caged needle roller bearings to provide the highest possible RPM.
