Fluidyne High Performance RDO.TRX.2124 Extruded-Tube Aluminum Radiator 2021-2024 Ram TRX

The Fluidyne High Performance RDO.TRX.2124 is a direct-fit, extruded-tube aluminum radiator engineered specifically for the 2021–2024 Ram 1500 TRX. Built to handle the extreme thermal demands of the supercharged 6.2L Hellcat V8, this radiator delivers a significant upgrade over the factory cooling system in both durability and heat transfer performance.

At the core of this radiator is Fluidyne's proprietary one-piece die-extruded tube technology — the same construction trusted in NASCAR radiators and oil coolers. Unlike conventional radiator tubes that are formed from flat aluminum and sonic-welded, Fluidyne's tubes are extruded as a single piece of aluminum, eliminating the weld seam and brazed joint failure points common in OEM and most aftermarket designs.

Key Features:

• One-piece die-extruded aluminum tube core construction
• Race-proven technology derived from NASCAR cooling applications
• Direct-fit replacement for 2021–2024 Ram 1500 TRX
• High-density proprietary fin design for maximum heat dissipation
• Thick aluminum end tanks for added durability and pressure resistance
• One of the densest cooling cores available for this application
• Eliminates common failure points found in OEM and folded-tube aftermarket radiators
• Backed by over 30 years of elite cooling system engineering

The Fluidyne RDO.TRX.2124 is the purpose-built solution for TRX owners who demand reliable cooling under hard off-road use, high-performance driving, or any condition where the factory radiator falls short. It is designed and manufactured by Fluidyne High Performance, a U.S.-based leader in advanced automotive and racing cooling systems.
