  Received. A+ seller looks like quality parts condition looks good great price for the value that’s here. Appearance looks just like the pictures. I was missing the intake gasket and as soon as I let the seller know, they replied with in an hour and got it sent out to me the next day. These guys are awesome to work with

  Ordered an engine kit for a 5.9 cummins. Showed up earlier than expected. As most kits for the cummins it came with 1 cam bearing and I happen to have a block that took 2. When I contacted them and asked for a price so I could buy another bearing they responded with the tracking number for another bearing. No argument and only question asked was if it was the same as the front bearing. A++ this company goes above and beyond.

  Above and Beyond Service! I accidentally purchased the wrong pistons, but the seller handled the situation incredibly well. Not only did they send me the correct pistons super fast, but they didn’t even charge for the new shipment and provide a free return labe for the wrong ones to be returned. I’ve never experienced such outstanding service on the eBay platform. Highly recommend this seller for their exceptional communication and professionalism. I’ll definitely be purchasing from them again!

  Great transaction and fast shipping. A part was missing from the kit when it arrived but I contacted Grumpys and they sent one out straight away. I enjoy doing business with Grumpys! I highly recommend them. Thank you and have a great weekend
