First time I've used Docs Diesel oil, filter, cabin filter. So far so good. There is no tick that'd you commonly hear with other oils and the cabin filter thick heavy duty. I will buy again. Ive been using the def guard for couple months now and I think it helps
I can only speak to the Doc’s oil filter from a visual perspective because I haven’t installed any yet. The only difference is that the Doc’s filter is about a 1/4” shorter than the Motorcraft filter. I change my oil and filter before the recommended intervals so this does not concern me.
Perfect fit. Was worried about throwing a code not being OEM, but everything was fine. A little disappointed in how long it took to receive them, but it ended up working with my schedule.
First time ordering through Doc’s. Ordered two of the 6.7 Powerstroke filter kits, plus extra oil filters. Every filter fits like OEM filters. When you place Doc’s oil filter next to a Motorcraft oil filter the Doc’s filter is a bit smaller, maybe a 1/4” difference. But the price reflects it and I change my oil at shorter intervals than recommended so I'm not overly concerned out a little less filtration.
It's nice to find everything for servicing your truck in stock at one location.
This is my new favourite hoodie (I have a lot of hoodies) but the design is spot on, love the clean look. And it’s insanely comfy and fits perfect in a size large. Thanks Docs Diesel!
good quality, complete kit, good shipping. Good Price. awesome .
Fit and finish is great. No complaints from me.
Great filters
Just installed my first order from Doc's. Fuel filters and CCV filter. Everything fit as they should and appear to be good quality.
Since i started using Docs filters, it's had become cheaper, easier and better for my ole truck. Order, wait, receive. install that easy l
These hub bearings worked perfect for my 2017 Ram 2500 Cummins. Went pretty smoothly. Sort of self explanatory. Quality hub bearings. No more noise. I also changed front brakes and rotors since I had to remove them anyway.
So far pretty pleased with Doc’s products for my 2022 Ram 3500, 6.7L, 68RFE, LB, DRW. Sometimes feels like they are a little slow to ship, though
Fit like a glove, easy to install . Great price with superior shipping. Use Docs and save yourself a trip to box stores & money.
I like that I didn’t have to go to a store to buy what I needed and to then have to bring it all home just to find that I eight F_Ked up or an employee of the store got me the wrong part. I know I get that it’s still my fault if an employee of the store(s) hand me the wrong thing but when life and business gets in the way $#!t happens; and, that is my point. All that I need to do is order the kit a couple days before you plan to do the work and the box is right there to be positioned in place for the job. The parts seem to be of great quality and as a veteran I get eleven percent off. So far I am sold on Doc’s.
Just replaced my fuel filter and air filter on my truck. Products match perfectly! Will be reordering soon.
