Bought and used on my yz450 quality seemed to be good been running them for 80+ hours and they hold up,they do require the kib spring set to with them (witch is kinda spendy) but overall worth the money

Good product, shipping was good.

Toughest valves available! Hold up great in a highly built 4 stroke engine that takes a lot of abuse.

The spring kit fit amazing, and i noticed a little difference in the power! 2nd time purchasing them for two separate bikes!
