Black Widow Stage 2 47/48 650 HP Max

The Black Widow Stage 2 47/48 from Next Level Engine & Transmission is engineered for trucks that demand more — more power, more durability, and more control. Rated to handle up to 650 horsepower, this transmission is a major step up from Stock and Stage 1, built for high-output daily drivers, heavy tow rigs, and tuned performance trucks.

Each valve body is custom configured to match the customer’s specific truck setup and individually tested prior to installation, ensuring optimal hydraulic performance, shift quality, and pressure control for every build.

The Black Widow Stage 2 features upgraded clutch packs, enhanced valve body modifications, billet internal components, and reinforced hydraulics for improved line pressure and crisp, consistent shifts. It’s designed to perform under load, handle added torque, and deliver lasting strength in real-world conditions.
