GM Radiator 15.125x22.87 Extra Steering Clearance

The GM Radiator 15.125x22.87 Extra Steering Clearance from AFCO Racing Products is purpose-built for high-performance street and track builds where engine bay real estate is at a premium. Manufactured by AFCO, a leader in cooling system innovation for modified vehicles, this aluminum radiator solves a critical clearance problem faced by serious GM enthusiasts: fitting a full-size cooling core without interference from custom steering racks or tight engine compartment configurations. Whether you're running a heavily modified LS-based engine or working within a custom chassis, this radiator delivers the thermal capacity you need without compromise.

Built from lightweight aluminum construction, the GM Radiator features a compact footprint of 22.875 inches wide by 15.125 inches tall with a slim 3-inch core depth—dimensions engineered to maximize cooling efficiency while minimizing intrusion into the steering column envelope. The driver-side inlet and passenger-side outlet configuration allows flexible plumbing integration with custom cooling loops and remote reservoirs. At 16.9 pounds, the aluminum core provides excellent heat dissipation for turbocharged, supercharged, or naturally aspirated applications without adding significant weight, a critical factor in chassis dynamics and fuel economy on street-driven builds. The natural aluminum finish resists corrosion and maintains a clean engine bay appearance while the precision construction ensures reliable performance through sustained high-load driving conditions.

This radiator is ideal for GM platform builds—especially LS and LT engine conversions—where custom steering geometry or mid-engine layouts demand unconventional cooling solutions. Installers should verify plumbing port locations against their existing hose runs and confirm mounting boss alignment before final fitment. The compact 7.5-inch width allows mounting in tight lateral spaces, making it suitable for restomod applications, street rod conversions, and track-focused vehicles where factory cooling systems prove inadequate. Professional installation with quality coolant and a properly functioning water pump is essential to realize the radiator's full thermal potential.
