Ram 2500 Transmission Cooler & Line Kit - Fleece Performance - `13-`18. This direct-fit transmission cooler and line kit is built for 2013–2018 Ram 2500/3500 trucks with the 6.7L Cummins, offering a durable upgrade to help manage transmission temperatures during towing and heavy-duty operation.

The Fleece Performance kit replaces the factory cooler and uses vehicle-specific lines and fittings for a tidy installation. By increasing cooling capacity and improving fluid flow, the kit helps maintain more consistent transmission temperatures during sustained loads, which can support shift quality and component longevity when towing or hauling. The kit includes pre-bent hard lines, necessary fittings, and a cooler core sized for heavy-use applications. It is intended for owners who want a reliable, OEM-style installation without extensive modifications.
