The Texas Speed Tuner Supercharger Kit, Powered by Rotrex, is a high-output forced-induction system for GM trucks equipped with 4.8L, 5.3L, 6.0L, and 6.2L LS-based engines. Designed for combinations ranging from street-driven builds to high-horsepower applications, the system offers smooth, linear boost delivery with support for builds ranging from approximately 600 HP to 1,200+ HP, depending on configuration.

The bolt-on bracket system utilizes factory mounting locations without requiring block modifications. Boost and power output can be adjusted through supercharger pulley selection, while the smart idler arrangement allows multiple configurations to use the same belt routing.

IMPORTANT NOTES

ATI Performance Balancer is not included.
Boost and horsepower output vary based on supercharger pulley selection, engine combination, supporting modifications, fuel system, and tuning.
Proper calibration is required for the completed forced-induction combination.

Note: Verify engine, accessory-drive, and vehicle compatibility before installation. Final power capability depends on the complete engine and vehicle combination.
