Complete 2019–2020 Ram 6.7L Service Kit — Both Fuel Filters + Oil Filter
When Ram updated the 6.7L Cummins fuel system for 2019, they changed the rear filter design. The 2019–2020 trucks use a 68436631AA cartridge-style rear filter instead of the canister-style 68157291AA used in earlier years — but they kept the 68157291AA as the front (underhood) filter. That means you need two different fuel filters plus an oil filter at every service. This iFJF Complete Service Kit bundles all three exact-fit filters into one purchase.
One box. Three filters. Everything you need to keep your 2019–2020 Ram 6.7L Cummins running clean.

⚠️ 2019 was a transition year. Some early-production 2019 trucks may still use the older 68157291AA rear filter design. Verify your filter housing type before ordering — this kit is for trucks with the 68436631AA rear cartridge filter and 68358393AA housing assembly.
What's Different About 2019–2020?
For 2019, Ram redesigned the rear fuel filter housing. The new system uses a 68358393AA filter assembly with a drop-in cartridge element (68436631AA) under a removable cover (68436815AA). This is a simpler, cleaner design than the older screw-in canister — but it uses a different filter than 2013–2018 trucks.
Meanwhile, the front filter position (underhood) continues to use the 68157291AA element across 2010–2020 model years, and the oil filter (5083285AA) remains unchanged. This kit covers all three correctly.

Installation Notes
Front Filter (68157291AA): Under the hood, driver-side. Use a 29mm socket on the cap, swap element and O-ring. 10 minutes.
Rear Filter (68436631AA): Under the truck, driver-side frame rail. Remove the 68436815AA cover, pull the old cartridge, drop in the new one. The key advantage of the 2019+ design — no drain pan needed, the fuel stays in the housing. 5–10 minutes.
Oil Filter (5083285AA): Passenger side of engine block. Standard spin-on replacement during oil change.
Frequently Asked Questions
Q: Will this fit my 2019 Ram 3500?
A: Yes, if your truck uses the 68436631AA rear filter (cartridge-style housing with a removable cover). This applies to nearly all 2019–2020 Ram 2500/3500/4500/5500 with the 6.7L Cummins. If your rear filter looks like a canister (same as the front), you may have an early-production 2019 and need the 68157291AA rear filter instead — contact us to confirm.
Q: Does this kit include the 68436815AA cover?
A: No — the kit includes the filter element only. Your factory 68436815AA cover is reused.
Q: How often should I replace all three?
A: Replace both fuel filters together every 15,000 miles (or 12 months). Replace the oil filter at every oil change according to your truck's oil life monitor. Bundling all three in one order saves on shipping and ensures you always have spares.
Q: What oil should I use with this oil filter?
A: Ram specifies 5W-40 full synthetic diesel oil meeting API CJ-4 or CK-4 for the 6.7L Cummins. Capacity is approximately 12 quarts.
Q: Is the 68436631AA a genuine Mopar filter?
A: This is an iFJF aftermarket filter manufactured to meet or exceed Mopar specifications. It is produced in our IATF 16949-certified facility — the same quality certification required for OEM supply chains.
