Street Spool Turbos

MOMENTUM WORX Street Spool Turbochargers

When you want serious horsepower without sacrificing street manners on a CAT, CUMMINS, or DETROIT, the Momentum Worx Street Spool Series delivers. Designed around premium dual ball bearing center sections, these turbochargers offer lightning-fast response, exceptional durability, and the airflow needed to support everything from high-performance street builds to weekend race trucks.

Available in GT47, GT50, and GT55 frame sizes, the Street Spool lineup covers a wide range of horsepower goals while maintaining the drivability that makes your truck enjoyable on the street. Whether you're chasing 700 horsepower or building a four-digit setup, there's a Street Spool turbo engineered for your combination.

Unlike traditional journal bearing turbos, the dual ball bearing design reduces friction, improves transient response, and allows the turbo to reach operating speed more quickly.  When paired with tight divided exhaust housings - this combo makes for what we call the STREET SPOOL.  The result is faster spool-up, improved throttle response, and a wider usable powerband—perfect for trucks that see both daily driving and recreation competition use.

Every Momentum Worx Street Spool turbo features premium billet compressor wheels, high-flow turbine designs, and precision-balanced rotating assemblies to provide reliable performance under extreme conditions. 

If you're looking for the sweet spot between instant response and massive airflow, the Momentum Worx Street Spool Series is the answer.
