Engineered for serious performance, the Tech-line coating is designed to handle temperatures up to 1700°F continuously and up to 2000°F for short periods.

When it comes to quality, durability, and flow, Steed Speed builds some of the finest manifolds on the planet 🪐

P/N 800191 heading out today 🇦🇺

6.5 Litre Chevs are susceptible to crankshaft breakage due to OEM Damper failure.

By installing a Fluidampr viscous damper you will address this issue and reduce wear on the main bearings and timing gear, achieve more accurate valve train operation.

The Fluidampr automatically adapts to your modifications, then continuously self-tunes in real time to optimum damping at both peak levels and across a broad changing frequency range 🤘🏻

Fluidampr also offers lifetime warranty 👌🏻
