Product Description

The CSF 8344 is a high-performance transmission oil cooler designed specifically for Jeep Wrangler JL and Gladiator JT models. It features a 1-row, micro-tube core with a 10-channel design to maximize cooling efficiency while maintaining compact size. The cooler has a dual-pass flow to increase fluid contact and heat rejection.

With its 19 rows of tall multi-louver fins and all-aluminum TIG-welded construction, the 8344 can handle heavy-duty use - especially in off-road, towing, or high-load conditions where transmission temperatures often exceed safe limits. The unit holds ~68% more fluid than the stock cooler, making it ideal for serious driving.

Installation is made easy with OEM-style inlet/outlet ports and mounting brackets, meaning it drops in without extensive modification. Once installed, the CSF 8344 offers significantly improved transmission temperature control, helping protect your gearbox and improve longevity under demanding use.
