Speedy shipping.

Everything came and they let me know that some items (60 lb. Springs) were backordered. I appreciated them letting me know, and everything still showed up quickly.

Received - parts were OEM Cummins as advertized - Well packaged arrived in pristine condition - Excellent! Thank you!

Merchant advertised a part I needed which was right around half the price of those sold from other, more popular merchants. Item arrived to my house in Washington state from the merchant's location in Florida in ONE WEEK! Item was brand new in OEM packaging. I couldn't be happier with this merchant!
