Great Customer Service. Reputable Business
Thank you for the honest and speedy reply. I expect that from a reputable business and very much appreciate it. I only wish you had an engine cover to fit my motor. Let me know if you decide to fabricate one for my vehicle. You have fine products. I appreciate the sincere call from Katie and adjusted my rating accordingly.
Original Post
I ordered an engine cover for my 1999 7.3L Powerstroke Ford F250 XLT. Got the part in a reasonable amount of time. It looked amazing and very well built. It didn't come close to fitting my motor. Tried calling customer service CS and was prompted to use the contact us link. I received an RMA in an email with instructions. I mailed it back at my expense ($57) requesting an exchange. I sent another note in the same fashion due to no mention of exchange. Katie
from CS called and left a message that this part did not fit early 1999 model years. Their website part description states, in part .."Fits 1999-2003 Powerstroke." I called Katie back and asked for a "return shipping" refund since this was not my mistake. She said no. Great product, poor return policy for legitimate returns.

Hi Doug, I forwarded this to Customer Service this morning. We appreciate the honest feedback and the opportunity to improve. You are correct, the website does need an update regarding that product, and as I understand, Katie has reached out to make sure you are being fully refunded. We work hard to provide a 5-star experience to each customer, and hope you will give us another chance in the future.

Parts ordered were packed well i protective packaging and shipped quickly. Received everything in approximately 4 days in very good condition, all parts fit exactly and were very easy to install. Degas tank and coolant bypass filter kit both installed in less than an hour! Very pleased with the materials and workmanship on the parts, they look great. Will be making more upgrades to my 6.0L soon using Sinister Diesel parts!
