Wiseco Crankshaft Assembly: WPC131A
HONDA TRX400EX 1998-2004
Kit Contents:
Wiseco Crankshafts: Wiseco power sports crankshafts feature a double-forged connecting rod made from dedicated forgings. The rods maintain superior strength, durability, and dimensional consistency through improved gain flow. Shot peening eliminates residual stress, and oil slots are located to maximize lower rod oiling and extend bearing life. 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 peace of mind that your motor will be able to withstand any abuse within reason.
