Excellent service

Order filled correctly and arrived quick & secure.

Thanks for the kind words Roy!
super service

ordered product on the weekend, received notification it was shipped, received next day. Absolutely fantastic service from Diesel Parts and courier. Just to clarify why I'm impressed with overnight service is that the product was shipped on Monday morning from Edmonton Alberta and delivered in early afternoon in the interior of BC (Sorrento BC). Any time I order from Amazon (I'm a prime member) the best they say they can do is 5 days from their outlets in Calgary or Vancouver.

We aim to impress Greg! Thanks for the support!
