The Wiseco PK1779 Top End Rebuild Kit provides everything needed to overbore or rebuild the top end of your Yamaha Kodiak 400 or Big Bear 400. This complete kit is designed for 84mm bore applications and includes premium Wiseco forged pistons engineered for durability and performance in demanding ATV conditions.

Kit Includes:

  • Forged piston(s) - Wiseco 4676M series construction for superior strength

So far, so good

Thank you for the great prices

Fair price for the item I purchased and the shipping wasn't more than the item. Most other sites wanted double the cost of the item for shipping.

easy

found exactly what l was looking for in a hurry!

Fast check out

Quick and easy ordering and check out.

I like it because all prices are compared right here in one place. However, I don't like that reviews are generalized about whole site and not individual items

great price hope for quality now

quick and easy

Straight up , seamless process

woohoo
