Let customers speak for us
Thank you doc's for always keeping my beast ready for battle.
Oh yeah this kit is perfect...just remember to position your catch can so that it actually catches your old fluid instead of just pouring it on the floor!
Top Notch products !! I’ve been using Doc’s oil and fuel filters for the past couple years, zero issues with them on my ecodiesel! I’ve used their air filters, continue to use their cabin filters, wiper blades, and diesel treatment. No reason to shop elsewhere. Get it done right the first time with Doc’s !!!
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.
This tool saves you so much time and mess you will wonder how you changed oil without it.
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
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. 😂
Very nice product at good price would recommend to anyone who likes to take of there dodge ram 6.7 Cummins like I do thank you Docs
Needed to do trans service so why not do the one stop shop at Docs just had to buy another gallon went with a deep pan and a thermal bypass
Everything is top quality and as advertised. Fit is perfect. Will be my go to for all future services.
This is the perfect kit. Everything is quality constructed and fits perfect. Will definitely order this every time I'm due for service.
After ordering many filters I’ve always used power service
Filters were great so I decided to try this treatment
Bought a fuel filter and the quality seems amazing and got some really cool stickers with my order
This guys are on top of things when it comes to service. Almost feel like they communicate with my truck.
I’m about to order the front hubs, it’s that time. Overall 5 stars.
