RADREPLA DPI2101 3-Row Aluminum Radiator Kit for Jeep Wrangler TJ/YJ 1987-2006 with 16" Fans

Premium cooling for Jeep Wrangler TJ and YJ (1987-2006)

Upgrade your Wrangler with the RADREPLA DPI2101 3-row aluminum radiator kit. Crafted from AA5052 aircraft-grade aluminum, this core is TIG-welded and 100% leak tested to withstand demanding trail days and daily driving. The result is a rugged, lightweight upgrade designed to move heat efficiently and stand up to harsh conditions without adding unnecessary weight.

The 3-row core increases surface area and airflow, helping heat exit the engine more quickly. Paired with a purpose-built aluminum shroud and robust 16" fans, the system aims to maintain steady temperatures under load, in desert heat, or during slow climbs on rugged terrain. While not a guarantee, drivers may experience improved cooling performance and longer cooling system life under tough conditions.
