Good so far

Replaced wheel bearings with these at same time as doing ball joints on my 2019 Ram 3500 6.7 SRW. Install was easy and immediate improvement. Time will tell on longevity.

Don't change oil filter without it!!!

This tool saves you so much time and mess you will wonder how you changed oil without it.

Cant wait to install!

Fast shipping! Great service! Time to remove the old CCV and doc's had what I needed. Going to be installing this this weekend and remove the old CCV.

Second time I’ve ordered all filters for my truck
Will continue for quality and service
Fuel treatment also

Great Products

Loving the company and products... easy to find my filters. Been ordering from them for 5 months now. Ordering is fast and shipment is always on time...
Only thing that needs to change is the stickers they send in box. Got way to many of the same. Need new stickers for every month. 😂

After ordering many filters I’ve always used power service
Filters were great so I decided to try this treatment

Couldn't be happier

Bought a fuel filter and the quality seems amazing and got some really cool stickers with my order

filters

best filters on the market hands down! great customer service and all around company as well! will continue to buy everything from docs diesel

Amazing customer service!

Great quality filters! Great prices and most of all amazing customer service! I ordered a filter kit and the box was damaged along with the air filter due to improper packing. Contacted them and within 30 min they responded/apologized and had a new filter on its way to replace as well as insuring packing issues would be looked into and taken care of. Which when I received my new air filter it was packaged neatly and securely. Highly recommend and will continue buying from Docs Diesel!

Hey Will, thanks for the honest review. We won't get better as a company unless we look into what our customers tell us we are doing wrong. Every little bit of positive critiscism helps. Thanks for shopping Doc's!

I almost shouldn't but have to

I placed an order with Docs for routine maintenance stuff. Docs got it boxed up and shipped out in good time. Ups on the other hand decided that Docs was treating me way to good. On the day of delivery Ups decided it would be good to just leave my box sitting out in a complete downpour rain event. Now had they locked on the door to notify my wife this wouldn't have been so detrimental. Upon arriving home from work I noticed a soggy wet box sitting on my walkway. Every filter and box inside had been soaked with not just rain but fuel treatment as well. Apparently Ups is not very gentle with our packages. I notified Docs and without hesitation they shipped all the damaged products a second time. I am not writing this to give people ideas or anything but to let people know that this is a great business that stands on customer service. Thank you Docs for handling this situation and taking care of your customer.

Hey Jeremy, as you know we take our customer satisfaction seriously here at Docs. We were sorry to hear your product was handled poorly during shipping the first time, but we're glad we could make it right and get you the products your truck deserves!

Love the products. Keeps my jeep going

Bent filter

The filter was dented when received. Seems to be working okay as I haven’t noticed any leaking but was a little worried about that when installing.

Love Doc's Diesel

Always fast delivery, Always great products! Fuel filters, oil filters, oil, air cleaners, all of it works great!!

First purchase

Packaging was great, all came in one box. They through in some stickers which as any other person that works in construction knows we love stickers. Both air filters fit great, both fuel filters fit great as well as oil filter. The filter plug is a must. I couldn't imagine the mess I would have made on the concrete if I didn't have it.

Excellent

Order was quick. This was my 2nd time using this for my truck. Perfect .

Fuel Filter

Easy to replace
Perfect fit
Keeps the fuel clean

Doc’s diesel only #1

Doc’s diesel has proven to have quality parts that i am proud to use in my truck definitely recommend to all my diesel brothers and sisters

Rear brakes on 2015 ram

Brake kit arrived quickly, and was packaged well. The initial look at them appeared well made and clean. There is even (1) package of brake lube that comes with them, luckily because I had forgot to pick some up. All in one package that installed well and I’m sure will last quite some time. I will update with any negative or positive changes happen. Will be ordering front kit soon and will do a handful of pictures for the install.
