Great Product
Had everything needed to replace the crank and main seals. Price was outstanding especially when compared to the cost of an OEM crank assembly. As far as the products endurance, who knows.

Perfect
Fit was perfect, install was by web advice (freeze/heat). I didn't purchase an expensive shim device to stabilize before install, but took apart a gap feeler device, placed appropriate shims on either side of rod between rod and crank for a firm fit. Installed with crank at BDC. Had to hammer lightly on left half with a rubber malet to get cases together. Bilke runs like brand new.

Quality Item CR250
Crank looks good and has nice machine work done to it. Gasket kit is very nice with only 1 o-ring missing for cases (but includes both water pump seals!) Main bearings are quality Koyo brand - Same as OEM.

veery good quality crank kit
I was very pleased with the kit. the bearings are koyo (oem in many quads). i would say this kit is as good or better than stock, at a much better price. the gasket kit is very good also.

This is a great piece and is easy to change out. Wiseco cranks and pistons are all that I will run in my bike or any of my team's bikes.
