We just completed the first phase of Kane’s Great Adventure celebrating our 6 year old beating cancer!! 15,000 miles, 48 states, and 36 national parks, in 62 days! We only trusted Doc’s to keep us running smooth! Next up, 2 more states, 27 more national parks! LETS GO!

Works Great Fits Great Truck Breaths Great 👍

I bought the Ram 3500 after the first 10k mikes it was time for an oil change and i figured i do the filters as well, 750.00 , yeah no, i can do it myself for 250.00 and burn the old oil in my smudgepot, for heat in the back yard in the winter so, thats what we do. I can afford to pay the dealer but i cannot bring myself to pay 500 bux in labor for 45min of work.

These filters have never failed me. Been ordering them for years and always give the best protection for my 2019 2500.

Docs filters always fit right, and hold up well without the worry of inferior filter media separation. Reasonably priced, shipped quick. Couldn't ask for any better. Thanks!

The parts seem ok but I received a lot of flack from the Cummins community for buying from DOCs I didn't get one OK from anyone? The work had to be done because the Dealership I paid to service my truck the day after I purchased it didn't do everything I paid for before towing a camper 20k miles. When I pulled the transmission pan I found the OEM Filters from 2012 still on the transmission. It was shifting ok but definitely overdue at this point. Keeping my fingers crossed the replacements are not what everyone is telling me. Photo of old screw on filter attached

I’ve purchased rotors, hub assemblies, brake pads, fuel filters, and oil service kit and all of them fit and are good quality for a great price

👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻

Yeah, What the Fuel Mileage? The only thing I changed was my DEF choice to Doc's. I am also using the DEF additive from Doc's. My trip from Orange County CA to Astoria OR to Mountain Home ID and back was the best MPG I have every reached. My rig is not light and I would say its anti-aerodynamic, but 15.8 mpg overall is 2.2 mpg more than the last 3 exact trips. With a 52gal tank, that 2.2 is significant. Soooo.... Doc's is the boss . .

This is exactly what everyone with a diesel truck needs! Great products that fit and actually work! Never let me down yet and I am a Hotshot trucker so my truck is constantly being used and so are Doc’s products.

What a stand up company!!, had an issue with a couple of missing items that had been ordered, sent a couple emails , left a message , was contacted via telephone, was reassured that said items would be shipped out , and that they where ! Stand up customer service , I’m greatful I stumbled onto you all ! Have my biz for the foreseeable future!

I purchased my 2015 Chevy Silverado 2500 LTZ Duramax brand new in 2015. Just rolled 200 thousand miles and my first set of rotors and only the second set of Pads. Excellent Product and will be using them again when needed.

Easy installation fits good on the truck

I was able to get everything I needed in this kit for a really good price. Saved a lot of money where normally I would have to source everything at O'Reilly's or Napa. I was very happy with this kit everything was as it should be and it made it a breeze being able to have it all shipped right to the house. I will definitely be using Doc's Diesel from now on.

I got this kit for my 2022 gladiator eco diesel. I found it to be convenient to have all the correct components delivered. All the parts were perfectly fitted to my truck and it’s no hassle to buy from doc’s. i have a subscription as a failsafe for my failing memory.

Great oil and filter combo second time running it absolutely no problems.

I have to use this product a little longer to give a gain evaluation, but by some strange coincidence my 2022 jeep gladiator eco diesel is getting precisely 24.7 miles per gallon. I’ll update this in the future but also I would encourage doc to formulate a 30/0. I love this truck and hope to make it last so I’ll keep using doc’s secret sauce. I also got a full filter and oil kit. everything fit perfectly thanks.

I have been using Doc since I first bought my truck and have never looked back!! The only thing missing is a Doc Diesel beanie!!! I don’t wear ball caps just Beanies!lol!

Worked great once again. Fast shipping. Exact sizes I needed

ordered oil, filters, and fuel filters. Called because I thought I had the wrong oil filters, and someone called me back. a real person. This was for an F-350, 2026

Great product that was as described. I will be purchasing from Doc's diesel again the shipping was fast and the website was easy to use.

Another home run from Doc’s. A quality, fair priced filter kit. Two fuel filters and one oil filter with o-rings for the Cummins 6.7 A convenient solution for today’s diesel trucks. Mine in particular. lol. Thanks y’all

Doc's is great to deal with even with their recent move to the new facility the order was fast and on time. Great service and products are priced comparable to others yet the quality is much better.
