Everything arrived well packaged and in good order... It was shipped promptly, but hey, no accounting for the snow storm in the NW... I think UPS calls it an "act of God"... Thanks

Ordered Monday, delivered Thursday - just as promised. Best price among all reputable on-line parts dealers. Saved at least a third off the most popular dealers.

Great selection and fast shipping. Not to meantion the lowest prices anywhere on the net.

I ordered a Tokico shock and everything went great. Shipping took a few days and it came in good condition and at a great price!

Great prices.
