Most PK/SK/WK/VT kits from Wiseco feature a complete top end gasket kit that gives you everything you need to complete your rebuild from premium materials. 4-stroke race applications feature Wiseco’s ArmorGlide™ skirt coating to provide reduced friction and noise to contribute to increased horsepower.
I have never had a problem with Wiseco topend kits. This is the 3rd one I have purchased and the 1st I replaced 3 years ago on a kx80 still running strong with 22 hours on it and pulled top end off to ck rings and measure piston still ok.
