Texas Speed & Performance Gen V 5.3L Stage 2 L83TR-2 Camshaft

218/226, .635"/.635", 113 LSA

The Gen5 L83 5.3L engine utilizes Variable Valve Timing (VVT) controlled via a cam phaser. A cam phaser is a computer-controlled cam gear that automatically optimizes camshaft timing based on the current engine RPM. While this technology provides tremendous efficiency benefits, it presents a challenge when designing performance cams due to the wide range of valve timing movement and constantly changing piston-to-valve clearance. With the help of Texas Speed's Superflow 902 engine dyno, they're able to custom-design camshafts and phaser tuning tables to allow Gen5 L83 customers the ability to purchase the ultimate in L83 performance camshafts! Thanks to the Superflow 902 dyno, Texas Speed is the only company that currently offers a VVT camshaft with a phaser table included to properly tune the camshaft phaser once it's installed in your 2014+ L83 truck!

The Texas Speed & Performance L83TR-2 camshaft is a great choice for the enthusiast looking for an additional jump in horsepower without sacrificing much driveability. It will have a slight lope at idle and drive similar to stock. It does remove the factory AFM/DOD system that deactivates cylinders, but it retains the variable valve timing (VVT) system that allows the engine to advance and retard the cam while the engine is running. This provides a much better power curve since the engine can advance the cam in the lower RPM's for better torque and retard the cam in the upper RPM's for better horsepower. TSP does recommend using the TSP .660" dual spring kit with PAC springs and titanium retainers and TSP hardened chromoly pushrods with this camshaft.

Each GenV L83 camshaft Texas Speed offers will require the use of a Comp Cams Phaser limiter kit. The phaser limiter restricts the range of cam timing movement to 20°. This modification provides the necessary valve clearance for serious performance camshafts with tighter lobe separations while still utilizing the benefits of the VVT technology.

Texas Speed recommends the +32% fuel lobe for any power-adder applications. The +32% fuel lobe will require the use of a lash cap, so please make sure that you install one during the camshaft installation!

All of TSP's L83 camshafts were designed on their SuperFlow 902 engine dyno using an otherwise stock 5.3 L83 engine. They design and test many different camshafts before selecting the camshafts that are offered to our customers. This provides TSP with a distinct advantage of offering the best power curve possible without sacrificing overall performance, as well as knowing that what's offered is also safe and will not have any piston-to-valve clearance issues. TSP tests their products before they're sold, so you KNOW that you are purchasing a camshaft that is proven!
