TSP LT LOW LIFT Cam Kit

TSP Gen 5 LT Low-Lift Camshaft Package

The Texas Speed & Performance Gen 5 LT Low-Lift Camshaft Package is designed around TSP LT low-lift camshafts, providing horsepower and torque gains without requiring the additional lift and valvetrain modifications associated with more aggressive camshaft packages. The package combines your choice of TSP LT low-lift camshaft with PAC ovate beehive valve springs, a phaser installation tool, and a 0-degree phaser lockout. Customers can also optionally add an HP Tuners MPVI4 for tuning support.

Note: Verify pushrod length, lifter preload, valve spring clearances, DOD-delete requirements, and tuning requirements for your specific application before installation. The HP Tuners MPVI4 is available as an optional addition to the package.
