Looking to upgrade your transmission cooling system on your 2003-2009 Dodge Cummins? FSD has you covered. We have vigorously designed & tested the perfect transmission cooling setup.

Wether you're towing, racing or sled pulling. FSD's elite cooler setup is exactly what you need. We managed to fit two massive oil cooler cores in the factory transmission cooler location holding more fluid then any other direct fit cooler on the market.

What this means for you is that you will get the same cooling from this as you would from running multiple massive remote coolers, but without the hassle and hefty cost of two remote coolers, wiring for fans, custom transmission lines & mounting. This set will drop right in and has an extremely easy installation.

We designed this kit with an AN braided hose kit & fittings that will adapt to your factory transmission lines. Additionally, we recognize that many have already purchased our factory replacement AN braided hose Kit.

No need to worry, the included line kit & fittings allow you to adapt directly to our AN braided transmission line kit if you already have it. No rubber hose, no clamps, all thread in connections to ensure the most secure & reliable setup possible.

Our kit consists of one MASSIVE oil cooler cores, precision tig welded stainless steel mounting brackets, Stainless Steel allen head screws and& flange nuts. To top it off we have an AN braided hose kit to connect to your factory lines or your existing FSD AN braided Transmission line kit. As always, this kit is made in the USA and is backed by FSD's lifetime workmanship warranty.
