Howe Racing Radiators: Race-Proven Cooling Built by Hand

When engine temperatures climb and laps are on the line, the last thing any racer can afford is a cooling system that falls short. Howe Racing Enterprises has spent decades engineering aluminum radiators that meet the brutal demands of circle track, modified, and road race competition — and their reputation in the radiator category is backed by verifiable performance advantages, not just marketing claims.

What Sets Howe Racing Radiators Apart

The foundation of every Howe radiator is its construction quality. These radiators are epoxy-free with 100% tube-to-fin contact for maximum heat transfer and dissipation. That means no bonding shortcuts — just pure metal-to-metal contact that moves heat out of your coolant as efficiently as physics allows. The result? Typically more than 7% cooler than a flux-bonded aluminum core and 15% cooler than copper and brass.

Craftsmanship is equally central to the Howe difference. Howe radiators are 100% hand TIG-welded by experienced craftsmen for exceptional quality and appearance. They feature billet filler necks and uniform-height core flanges, along with crimped and welded tanks that are hand-fitted to each core. Each radiator is pressure tested and guaranteed against manufacturing defects.

A Range Built for Real Racing Applications

Howe's radiator lineup covers a wide spectrum of racing configurations. The collection includes Crossflow with Cooler, Crossflow, and Double Pass radiator styles , giving builders the flexibility to match the right cooling architecture to their chassis and powerplant. Howe also offers models with built-in heat exchangers that save the weight of running a second, separate radiator — a meaningful advantage in weight-sensitive builds.

For Ford and Chevy LS-powered machines, Howe has developed a purpose-built Dual Plane Radiator. The straight lower portion aligns with air from the grille inlet for low restriction, while the angle of the upper plane naturally convects more air at low speed and directs air upward at high speed. It's the kind of detail-oriented engineering that separates a race-focused manufacturer from a generic parts supplier.

Need something that doesn't come in a standard size? Custom radiators may be ordered with a Howe custom radiator form, a complete drawing, or a sketch — making it possible to get a purpose-built unit for even the most one-off chassis builds. If you can draw it, sketch it, or provide a sample, Howe can build it.

A Legacy of Cooling Performance

Since 1984, Howe has remained a trusted name for dependable cooling performance and quality workmanship. Whether you're campaigning a weekly-night modified or preparing for a road race enduro, Howe Racing radiators are designed to keep your engine in its operating window when it matters most.
