I've been to their shop in California a few times. Very cool place, lots of displays to look at. Car parts on one side of the store, truck parts on the other.

They also pack a semi truck and sell at the swap meets in area, Pomona, Turlock, hot August nights.

They seem to sell the same items all the others do, so You will have to compare for the best price.

If you contribute to the site you get a few discount codes for a couple of the vendors that may beat truck shop prices

I did use their door seal kits and was very pleased with them.

There is come kind of relationship between the truck shop in orange California and the COUNTER PARTS brand we all seem to purchase.

The web site is easy to use and navigate.
In November they offer 10% discount with a post card they mail out if your on the mailing list.
