Filter Changes Made Easy
Doc’s Complete Filter Kits make filter changes simple by packaging everything you need in one box. No guesswork, no extra trips for parts, just the right filters ready to go. Regular maintenance keeps your truck reliable and efficient, and our kits make it easy to stay on schedule.
Fuel Filters
Doc's Fuel Filters are built to keep contaminants like dirt, rust, and debris out of your fuel system, protecting key components from damage. They’re designed to improve fuel flow and pressure, which helps your engine run smoother, respond quicker, and burn cleaner. Each filter is built with high-efficiency media and includes o-rings where needed for a reliable, leak-free fit.
Engine Air Filter
Doc’s Premium Engine Air Filters block out dirt, dust, and debris that can wear down your motor over time. The heavy-duty silicone gasket holds a tight seal, even when you're running in rough, dusty conditions, and deep pleated filter paper traps more grime to help your truck run longer, stronger, and more efficiently. The Micron + Efficiency Rating is 99.25% / 344.2G Dust Holding Capacity.
Oil Filter
Doc’s Premium Oil Filters are built to keep hard-working trucks running at their best. The high-flow synthetic media and heavy-duty metal housing work together to trap dirt, metal, and sludge before it can damage your engine. Compatible with synthetic, conventional, and blended oils, they deliver long-lasting protection that helps boost fuel efficiency and prevent overheating—mile after mile. 25 Micron @99% Efficiency Rating.
Cabin Air Filter
Clean air isn’t just for your engine — it matters for you too. Doc's cabin air filters trap dust, pollen, and airborne junk before it hits your lungs. Swapping yours helps cut down on sneezing, stale smells, and foggy windows. They’re easy to replace, usually right behind the glove box, and built for a perfect fit every time. Electrostatic media stops particles down to .001 Microns.

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.
Everything fit and worked like it was supposed to
Great kit. Recommend and will continue to purchase.
This kit is priced very well and everything fit and works perfectly. Definitely recommend!
