When it comes to enhancing the performance of your 5.3L LS truck, selecting the right camshaft is crucial. A custom camshaft from Summit Racing can add up to 40 horsepower, transforming your truck into a powerhouse. This guide will help you navigate the selection process, ensuring you choose the best camshaft for your needs.
Understanding Camshaft Basics
The camshaft plays a vital role in your engine’s performance. It controls the timing and duration of the valve openings, affecting how air and fuel enter the combustion chamber. A well-chosen camshaft can significantly improve your engine’s efficiency and power output.
Why Choose a Custom Camshaft?
Custom camshafts are designed to meet specific performance goals. Unlike stock camshafts, which are built for general use, custom options allow you to tailor the engine’s characteristics to your driving style and performance requirements.
- Improved horsepower and torque
- Better throttle response
- Enhanced engine sound
Factors to Consider When Selecting a Camshaft
Choosing the right camshaft involves several key factors that can influence performance. Understanding these elements will help you make an informed decision.
Engine Specifications
Before selecting a camshaft, consider your engine’s specifications, including:
- Engine displacement
- Compression ratio
- Intake and exhaust flow
Intended Use
Your camshaft choice should align with how you plan to use your truck. Whether for daily driving, towing, or racing, different cam profiles will suit different applications.
Lift and Duration
Lift refers to how far the valve opens, while duration is the length of time the valve remains open. Both affect engine performance significantly:
- Higher lift increases airflow, enhancing power.
- Longer duration can improve high RPM performance but may sacrifice low-end torque.

Tuning Your Engine After Camshaft Installation
After installing a new camshaft, proper tuning is essential to achieve optimal performance. A professional tune will ensure your engine runs efficiently and maximizes the horsepower gains from your new camshaft.
Conclusion
Choosing the right camshaft for your 5.3L LS truck can lead to significant performance improvements, including an increase of up to 40 horsepower with Summit Racing’s custom options.
