Performance Radiator for Mitsubishi Raider (2006-2009) 3.7L 4.7L

Heavy-Duty 3-Row All-Aluminum Performance Radiator for 2006-2009 Mitsubishi Raider

Direct-Fit Cooling Upgrade: Replaces the failure-prone factory plastic-tank radiator with a heavy-duty, all-aluminum 3-row downflow core engineered to maximize thermal dissipation under high-load towing and severe operating conditions.

The Stock Raider Cooling Deficiencies

Factory radiators in the ND-chassis Mitsubishi Raider rely on crimped plastic end-tanks bonded to single-row aluminum cores with rubber O-ring gaskets. Over years of thermal cycling, vibration, and pressure spikes, these composite tanks embrittle, leading to seam separation, hairline cracks at the neck, and catastrophic coolant loss. Furthermore, the limited surface area of the OEM single-row core struggles with heat soak when operating the 3.7L V6 or 4.7L V8 under payload or heavy trail conditions.

The Engineering Solution

This drop-in performance unit is fabricated entirely from 2mm aircraft-grade AA5052 aluminum with 100% precision TIG-welded seams, completely eliminating failure-prone plastic crimps. The 3-row racing tube-and-fin core dramatically increases internal fluid capacity and total heat-dissipating surface area. Featuring a CNC-machined billet filler neck, brass OEM-style petcock, and an integrated 5/8-18UNF transmission oil cooler, it ensures maximum fluid cooling efficiency without risking cross-contamination.
