Detailed Description

OSC part number 2841 is a direct replacement radiator designed for Jeep TJ and Jeep Wrangler applications that use TOC quick connects. The radiator uses premium aluminum tubes and a die-cut gasket approach to help maintain a secure seal, while the integrated transmission oil cooler supports vehicles originally equipped with cooler-in-radiator design. The core is built for OE performance and includes engineering updates aimed at improving cooling efficiency and service life in higher-mileage vehicles.

This part cross-references Spectra Premium CU2841 for the same application.
