GM Radiator 21 x 30.75 Dual Pass

The AFCO Racing Products GM Radiator 21 x 30.75 Dual Pass (model 80120N) is designed for high-performance General Motors engine platforms that require exceptional heat management. Ideal for modified or competition-level GM V8 engines, whether naturally aspirated, supercharged, or turbocharged, this radiator is essential for maintaining optimal engine temperatures during demanding driving conditions.

Featuring a dual-pass core design, this radiator allows coolant to flow through the tank and core twice, enhancing thermal efficiency by maximizing contact time with the aluminum cooling fins. Constructed from lightweight aluminum, it weighs 22.5 lbs and offers excellent corrosion resistance and heat conductivity compared to traditional brass-and-copper radiators. The compact design fits into tight engine bays, although some custom modifications may be necessary for optimal installation.

This radiator is particularly beneficial for those engaged in high-performance racing or track days, where engine temperatures can exceed stock limits. Its compatibility with GM V8 (LS-based platforms) makes it a versatile choice for enthusiasts looking to upgrade their cooling systems for better performance and reliability.
