TSP 1999-2013 GM Truck/SUV Cathedral-Port Dual-Spring Camshaft Package

A vehicle- and engine-specific Texas Speed cathedral-port camshaft package for GM trucks and SUVs equipped with 4.8L, 5.3L or 6.0L LS engines. This package combines your selected truck camshaft with the matched PAC dual-spring valvetrain components required for a properly supported installation.

• B.F.D. 5.3: Maximum-chop 5.3L profile for performance-focused combinations.
• Torquer V2 6.0: Broad-torque performance profile intended for 6.0L cathedral-port combinations.

Package Includes

• Your selected TSP cathedral-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

DOD/AFM note: Factory-DOD Gen IV 5.3L engines require the TSP Gen IV 5.3L Complete DOD/AFM Delete Kit. The 4.8L and non-DOD cathedral-port 6.0L engines do not use that kit.

VVT note: VVT-equipped applications require the TSP Gen 4 LS VVT Delete Kit when using these fixed-timing three-bolt camshafts.

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

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

Fitment: 1999-2013 GM trucks and SUVs equipped with cathedral-port 4.8L, 5.3L or 6.0L LS engines. Not intended for rectangular-port L92-style engines.

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