Your Transmission Cooling Hose Experts

Transmission cooling ducts in racing and performance vehicles route air to components operating at high temperatures, often routed near exhaust systems and engine blocks. The Heat-Flex GS and GN provide silicone-coated fiberglass construction designed for these elevated temperature environments while maintaining the flexibility to route through tight engine bays.

The Heat-Flex Raceflex is purpose-built for motorsport applications where weight, heat resistance, and packaging constraints all matter. For lower-temperature cooling runs — intake air ducting or brake cooling where exhaust proximity is not a factor — the Flexadux TR LT and Heat-Flex NS provide lighter-weight alternatives.
