Quick

Great quality and and I received very quickly.

I ordered a new clutch on June 12, and the item shipped the same day. Had the item on time as expected. They also beat all other retailers prices by a significant amount. Their shipping costs were also reasonable. The only issue I experienced is that it is virtually impossible to get order status from their Website if you do not have an account. Anytime I used the link provided in the order confirmation E-Mail would always return an error.

best price I can find on a motive brake bleeder anywhere. shipped same day - now that's great service!

best price on the net, GREAT communication.....

best price i have seen while i am searching in the interner :))
