Kennedy Diesel

Installed a twin lift pump and mega filter on an 2001 lb7 in 2010. Still going strong, hadnto replace the oil pressure sensor once but am overall happy.

I was having EGR issues with my 2006 Duramax and they helped me achieve the the outcome I was needing. I now have a 2010 Duramax and was having shifting issues and I contacted them via email and they answered all my questions fast and accurate. They recommended a new TCM and once received I threw it in and took care of my issue. They are helping with some tuning to my rig to help achieve the Duramax's full power without abusing my rig like all the company's that sell expensive plugins that cause issues over addressing power needs the correct way. I will keep using Kennedy diesel and recommend them to anyone wanting quality advice with excellent service.

I have an 08 duramax, was have trouble with low fuel rail pressure code, listen to what he has to say about after market injectors, I was out of town when I put in first bank of injectors, didn’t know of any local diesel shops or of Kennedy diesel at that time, purchased them from nationwide parts store. Got home went to same parts store change and purchased the other bank of injectors, still had trouble with code, so I opted to replace CP3 purchased that from a local diesel shop in my area, which is a great quality shop also, had them check my old one they confirmed it was bad, but after installing I still had same issue, pulled all injectors out and took them to the diesel shop, they checked them for me, 3 where over fueling, 2 where leaking, 1 was under fueling, replaced them with Bosch

Beware of this company. I bought an extreme duty fan clutch for my Duramax and after installing it I drove 8 miles and wasn’t watching my temps because I hadn’t even got out of town or hit any hills yet and my engine overheating warning flashed in front of my eyes. Truck says idle engine to cool down so I pulled over immediately and truck got up to 270 degrees. I installed my stock fan clutch on the side of the road and the truck was running at normal temperatures again as it always did. 18 hours into my drive my piston broke in half and I strongly believe it is due to the engine over heating so badly from this faulty item. Kennedy refuses to give me a refund, they want to send me another clutch. My engine only had 23000 miles on it and now I’m spending $13000 for another engine Andy busin

Had one of their twin lift pumps installed on my truck, followed directions to a t and within 3000 miles and 8 months the wiring harness corroded and fell apart when I unplugged it. I live in and extremely dry environment with no road salt. I called them and they said it's on me to replace the harness. I'm very upset with their customer service on a $600 part. This will be the last time I purchase anything or recommend them for any service.
