TSP 2007-2020 GM HD Truck/Van LY6/L96 6.0L Camshaft Package

A vehicle- and engine-specific Texas Speed camshaft package for GM heavy-duty trucks and full-size vans equipped with the rectangular-port 6.0L LY6 or L96. This package combines the selected TSP truck camshaft with the matched dual-spring valvetrain components required for a properly supported installation.

Choose Your Camshaft

• Truck Stage 1: Mild street, towing and work-truck profile with strong low- and midrange torque.
• Truck Stage 2: More noticeable idle with stronger midrange and upper-rpm performance.
• Truck Stage 3: Aggressive truck profile for performance-focused combinations with appropriate converter and supporting modifications.

Package Includes

• Your selected TSP rectangular-port truck camshaft
• TSP .660-inch PAC polished dual valve spring kit
• Titanium retainers, hardened spring seats and valve seals
• Texas Speed hardened 3/8-inch chromoly pushrods

VVT delete required: LY6 and L96 applications use factory variable valve timing. Add the TSP Gen 4 LS VVT Delete Kit when installing these fixed-timing three-bolt camshafts.

DOD/AFM note: Factory LY6 and L96 heavy-duty applications generally do not use DOD/AFM, so a DOD-delete kit is not included or linked. Verify the exact engine RPO before ordering.

Installation note: Verify engine code, cylinder-head port style, piston-to-valve clearance, pushrod length, timing-set compatibility and converter requirements before installation.

Tuning required: Professional calibration is mandatory after installation. No tune, tuning device, credits or remote tuning support is included.

Fitment: GM heavy-duty trucks and full-size vans equipped with the 6.0L LY6 or L96. Verify the RPO code before ordering.

Local installation: North Texas High Performance can provide separately quoted installation and tuning for local customers.
