Description
Take your GM LS engine to the next level with the Top Street Performance Pro Series Stage 2 Hydraulic Roller Camshaft. Engineered for enthusiasts seeking increased horsepower, stronger mid-range torque, and a more aggressive exhaust note, this performance camshaft is an ideal upgrade for naturally aspirated Gen III and Gen IV LS-powered street cars, muscle cars, performance trucks, and LS swap projects. Whether you're building a 5.3L street truck, a 6.0L performance build, or an LS-powered classic, this Stage 2 camshaft delivers the power and sound enthusiasts expect from a true street performance upgrade.
Featuring 216°/224° duration at .050", .553"/.553" valve lift, and a 108° lobe separation angle, this camshaft is designed to improve airflow, increase cylinder filling, and deliver stronger acceleration throughout the mid and upper RPM range. The more aggressive cam profile produces a noticeable performance idle while maintaining excellent drivability when paired with the proper supporting components and professional ECU tuning.
Manufactured from premium 8620 carburized nickel chromium molybdenum steel, the Pro Series Stage 2 Camshaft is precision ground for exceptional durability, wear resistance, and reliable valve train performance. The hydraulic roller design minimizes maintenance while providing consistent operation for demanding street and performance applications. A 3-bolt camshaft gear attachment ensures compatibility with properly equipped GM Gen III and Gen IV LS engines.
This Stage 2 camshaft is an excellent choice for enthusiasts upgrading 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L LS engines used in Chevrolet Camaro, Corvette, Silverado, Tahoe, GMC Sierra, Yukon, Pontiac GTO, and many LS engine swap projects. It is equally at home in street performance builds, restomods, weekend drag cars, autocross vehicles, and custom muscle cars looking for improved throttle response, stronger mid-range power, and an aggressive performance character.
For optimal performance, install this camshaft with the required LS6-style valve springs and verify piston-to-valve clearance, pushrod length, and timing components during installation. Professional ECU tuning is recommended to maximize horsepower, optimize idle quality, and ensure proper engine operation. Always confirm compatibility with your engine's cam sensor configuration, valvetrain components, and VVT or non-VVT setup before installation.

Q&A
What engines is this camshaft compatible with?
This hydraulic roller camshaft is designed for compatible GM Gen III and Gen IV LS-based V8 engines, including many 4.8L (293 CID), 5.3L (325 CID), 5.7L (346 CID), 6.0L (364 CID), 6.2L (376 CID), and 7.0L (427 CID) applications. It is compatible with many popular LS engine families, including LS1, LS2, LS3, LS6, LS7, LQ4, LQ9, LY6, L96, LM7, LR4, L59, L33, LC9, LH6, L92, and related LS-based engines. Always verify your engine code, valvetrain configuration, and supporting components before installation.
Is this Stage 2 camshaft suitable for street use?
Yes. This Stage 2 camshaft is designed for street and performance applications, offering increased horsepower, stronger mid-range power, and a more aggressive idle than a Stage 1 cam while remaining suitable for many weekend cruisers and performance street builds when properly tuned.
Will this camshaft work in a 5.3L LS truck engine?
Yes. It is compatible with many 5.3L LS truck engines when installed with the recommended supporting components. Always verify your specific engine code, cylinder heads, and valvetrain before installation.
Will this camshaft fit an LS1 or LS3 engine?
Yes. This camshaft is designed for compatible GM Gen III and Gen IV LS engines, including many LS1 and LS3 applications. Confirm your engine specifications and supporting components before installation.
Does this camshaft require upgraded valve springs?
Yes. LS6-style valve springs are required to provide proper valve control and reliable operation with this Stage 2 camshaft.
Is ECU tuning required after installation?
Yes. ECU tuning is recommended after installing this camshaft to optimize idle quality, drivability, ignition timing, fuel delivery, and overall engine performance.
What are the camshaft specifications?
This Stage 2 hydraulic roller camshaft features 216°/224° duration at .050", .553"/.553" valve lift, a 108° lobe separation angle (LSA), and an operating range of approximately 1,500–6,000 RPM.
What material is this camshaft made from?
The camshaft is precision manufactured from premium 8620 carburized nickel chromium molybdenum steel for exceptional strength, durability, and wear resistance in demanding street and performance applications.
Is this a hydraulic roller camshaft?
Yes. This is a hydraulic roller camshaft designed for compatible GM LS Gen III and Gen IV engines using a hydraulic roller valvetrain.

Yes. This Stage 2 camshaft is an excellent upgrade for many LS swap projects, including classic muscle cars, street rods, restomods, pickup trucks, and custom performance builds using compatible LS engines.
Will this camshaft have a lopey idle?
Yes. The 108° lobe separation angle (LSA) and Stage 2 profile produce a more aggressive, lopey idle than a Stage 1 camshaft while delivering increased mid-range and upper-RPM performance. Idle characteristics will vary depending on engine displacement, compression ratio, exhaust system, and ECU tuning.
What supporting modifications are recommended?
For best results, install this camshaft with LS6-style valve springs, inspect or replace the timing set as needed, verify piston-to-valve clearance, and perform professional ECU tuning. Many performance builds also benefit from upgraded pushrods, trunnion upgrades, and other valvetrain components.
