Derale Performance Cooling Fan, Clutch and Motor

Derale Performance: Decades of Keeping Engines Cool

Derale Performance is one of the most recognized names in automotive thermal management, with roots tracing back to Los Angeles, California. The brand operates as a division of CP Auto Products, Inc., a third-generation family-owned business that has been a California corporation since 1946. In 1963, Derale Performance became a charter member of the original Speed Equipment Manufacturers Association — the organization the world now knows as SEMA — cementing its place at the foundation of the performance aftermarket industry.

For well over fifty years, Derale has earned the trust of racers, hot rodders, diesel truck enthusiasts, and everyday drivers by building products engineered to tackle heat where it originates: at the engine. Whether the challenge is a trailered race car running at the limit, a diesel pickup hauling a heavy load, or a classic muscle car idling at a summer cruise night, Derale's engineering philosophy is the same — move as much air as possible, as efficiently as possible, without sacrificing horsepower or fuel economy.

What Derale Makes and Why It Matters

Derale's catalog spans the full spectrum of engine cooling solutions. The brand is widely known for its broad selection of engine cooling fan blades, including its legendary stainless steel flex fans that flex at higher RPMs to reduce drag and are rated for engine speeds up to 8,000 rpm. These belt-driven designs have been a go-to choice for classic and high-performance builds for decades.

On the electric side, Derale offers engine cooling fan assemblies in single and dual Powerpack configurations, featuring aluminum shrouds that can be polished, anodized, or painted to suit any build aesthetic. These ready-to-install assemblies are engineered for primary cooling duty and are sized to fit a wide range of vehicle applications. For builders who want flexibility or need to upgrade an existing setup, individual engine cooling fans are available in both electric and mechanical configurations, giving fabricators and DIYers the building blocks they need.

Beyond fans, Derale rounds out its product ecosystem with fan controllers, fluid and oil coolers, transmission cooling kits, oil filter relocation kits, and direct-fit cooling kits — giving customers everything they need to address heat from radiator to transmission.

Built in the USA, Engineered for Performance

What sets Derale apart from many competitors is its commitment to domestic manufacturing. Many Derale products are manufactured in-house at their Southern California facilities, and the brand actively sources raw materials and components from US-based companies wherever possible. This dedication to quality control at every step of production is a key reason the brand continues to be a benchmark choice across the performance and enthusiast communities.
