Clear LED Dodge cab lights
The cab lights I had ordered were exactly what I was hoping for. Simple plug and play direct replacement. Made it nice and simple. They even throw in a set of directions in case your truck didn’t already have cab lights. Very bright as well. Will definitely be back for headlights, taillights, and eventually more!

Good parts good quality
I appreciate the quality and quickness of arrival of their parts their welds and craftsman ship. However ups usually does horrible shipment and sometimes leaves knicks and scratches which can be annoying but that’s ups’s fault. All I ask of sinister is more sales products as I feel as some of their items overpriced yet I want to buy 80% of my parts from them I only buy some here and there because they are so expensive compared to oem

Ordered charge pipes and the process was easy. However, 12 days later the product hadn't even shipped with only one notification staying out would ship in 1 week. 10 days later it still did not ship. Sent an email to cancel order and they responded the same day.
Refund problem from cancelled order
I ordered and intake for my chevy pickup Sept. 14th 2020. I got comfirmation of the order and they charged my credit card for the item. A couple of days later I got an email that my intake was backordered and it would be 4-6 weeks before they would ship it. I cancelled the order and asked them to refund my credit card. It has been a week since I cancelled the order. I have called and they said I would get my refund within 5 business days. It has been 6 days and no refund!!!!! I need my money back. I don't want to pay interest on my money and wait 6 weeks for my part!!!!!
Thumbs up from me
Ordered two items. One came very quick, the other got back ordered and is taking longer to be delivered. Emailed them asking what the situation was and they emailed back a few days later to keep me updated.
