BOTTOM END REBUILD KITS<br />

Forged Bottom End Advantage<br />
The foundation of any bottom end rebuild is a solid forged<br />
crankshaft assembly, which provides strength and reliability far<br />
surpassing any cast part that lacks consistency. Forged crankshafts<br />
due to their lighter weight, more compact dimensions and<br />
better inherent dampening, rev higher and run smoother than<br />
their cast counterparts.<br />
This part of the engine has a huge amount of stress due to twisting<br />
and bending 1000's of times a minute while running under<br />
load, you don’t want an inferior product here to ruin a motor.<br />
Wiseco engineers have designed our crankshafts to meet or<br />
often exceed OEM tolerances giving you the best base for your<br />
bottom end.<br />

Crankshafts / Connecting Rods<br />
Wiseco powersports crankshafts feature a double forged connecting rod made from dedicated forgings. The rods maintain superior<br />
strength, durability, and dimensional consistency through improved grain flow. Shot peening eliminates residual stress and<br />
oil slots are located to maximize lower rod oiling and extend bearing life.<br />
Coated bronze thrust washers have a dimpled design to increase oil retention and reduces stress between the connecting rod,<br />
washer, and crank web. Double-drilled small ends provide the piston pin with extra lubrication and cooling, reducing distortion<br />
of top end due to thermal transfer from the piston.<br />
Wiseco has designed these crankshafts and connecting rods to work together with our pistons to provide the smoothest rotating<br />
assembly possible. Having a complete bottom end that is made of 100% forged material will give you the piece of mind that your<br />
motor will be able to withstand any abuse within reason.<br />
Professional racers as well as weekend riders choose these solid kits to reduce failure rates and take advantage of the horsepower<br />
and immediate torque a light weight bottom end can deliver.<br />

Bottom End Kit Features<br />
• Each kit contains everything you need to complete your rebuild the right way, the first time- crankshaft and connecting rod, all<br />
applicable bearings, and complete bottom end gasket kit made to meet or exceed OEM.<br />
• Wiseco connecting rods are double forged from a dedicated forging and feature shot peening, oil slots, and coated bronze<br />
thrust washers.<br />
• Bottom end gasket kits are made from premium materials, exceeding OEM standards, to provide exceptional seal between<br />
critical mating surfaces.<br />
• Main bearings are manufactured to the highest quality standards. Each is case hardened for maximum life and smooth operation<br />
at high RPM’s.<br />
• Corrosion resistant surface treatment to prevent corrosion and pitting over long term use or storage. This will add to the life<br />
as well the strength of the assembly.<br />
• Top end of rod is bushed for oil retention and eliminates pin galling. The bottom end rod bores are case hardened to 58-62<br />
RC to optimize bearing running surface.<br />
• The crank pin bearings are manufactured from the highest quality, hot rolled steel case hardened to 58-62 RC to extend the<br />
lifetime of the assembly.<br />
• Caged needle roller bearings to provide the highest possible RPM.<br />
