Consistency and reliability are a big plus when it comes to ordering online, so finding a business that delivers a great experience is a win! I will be using them again.

When I went to check my Amazon filter for dirt content inside the pleat the filter came apart! Docs are 100% better when it comes to quality. I feel comfortable to run the filter longer than 50% on my filter monitor.

Packaged well and received everything I

After installing these in place of some very worn out OEM pads I'm able to say I'm quite happy with them. They installed perfectly, and I noticed an instant difference with them.
My only minor gripe is with the replacement retention clips that are provided. They felt noticeably less durable than the old OEM ones and bent out of shape very fast upon trying to install several of the pads. I ended up simply transferring the old clips over to the new pads, and everything fit flawlessly.

I appreciate the convenience of ordering everything that I need from one site and the shipping is fast.

Quality product for a decent price glad to see they have some aftermarket stuff that works well and fits like it’s supposed to definitely recommend

How outstanding parts delivery was fast? Good quality parts. Keep my old Ram running forever. Thank you

Engine running smoother, and better mpg, great product

This is the second time I’ve serviced my transmission first time with this set up from Dr. Diesel took my 45 foot horse trailer above 10,000 feet and Colorado last week transmission shifted great temperatures were down 10 to 12° and the cost of this kit as well below others

Full package as promised. Will reorder when needed

I have been using Docs filters for a while now. Came time to replace the CCV and it was a no brainer where to get it from. Check out my install video!

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
