Fluidyne High Performance RGM.SLM.CLOSED.TPV2 Super Late Model Triple Pass Aluminum Radiator GM Closed System

The Fluidyne High Performance RGM.SLM.CLOSED.TPV2 is a race-engineered, all-aluminum triple pass radiator built specifically for GM-powered Super Late Model applications running a closed (pressurized) cooling system. Designed, engineered, and assembled in the USA, this radiator delivers maximum heat rejection for high-output competition engines where reliable thermal management is critical.

This unit features Fluidyne's proprietary LFT-Laminar Flow Technology, utilizing three rows of exclusive ½" tubes that accelerate and pressurize coolant flow to eliminate micro cavitation bubbles — a common problem with larger-diameter tube designs. The result is significantly more efficient coolant circulation and superior heat transfer under race conditions.

The closed system design uses a 1/4" NPT port instead of an open filler neck, making it compatible with pressurized cooling setups commonly found in Super Late Model race cars. This radiator-only unit does not include an oil cooler or fan, allowing builders to configure their cooling package to suit their specific application.

Key Features:

• Triple pass design for maximum coolant contact time and heat dissipation
• Three-row core construction using exclusive ½" tubes with LFT-Laminar Flow Technology
• Closed (pressurized) cooling system configuration — 1/4" NPT port, no filler neck
• All-aluminum construction with heavy-gauge tanks (>0.090") for superior durability and leak resistance
• Passenger side inlet / driver side outlet configuration
• Designed for GM / Chevrolet Super Late Model race applications
• Radiator only — does not include oil cooler or fan
• Designed, engineered, and assembled in the USA

Built for racers who demand uncompromising cooling performance, the RGM.SLM.CLOSED.TPV2 represents Fluidyne's decades of heat exchanger expertise applied to the most demanding short-track and super speedway competition environments.
