ProCharger has just announced its latest ProCharger 5.3 kit tailored for 2019–2025 GM trucks and SUVs, and the numbers are impressive. With gains of up to 55% more horsepower, these bolt-on kits transform everyday haulers into powerhouse performers without compromising drivability or reliability. Whether your priority is towing, highway passing, or just enjoying the thrill of instant torque, ProCharger’s new systems deliver.

From Stock 355 HP To 550-plus HP

At the heart of the upgrade is the 5.3L V8, a mainstay in GM’s truck and SUV lineup thanks to its balance of fuel efficiency and longevity. In stock form, it produces 355 horsepower. With ProCharger’s latest supercharger system, output soars to over 550 horsepower, more than a factory 6.2-liter, without sacrificing efficiency or long-term durability.

ProCharger making supercharger kits to improve every V8 on the road isn’t new, but the big news is this new ProCharger 5.3 Kit also optimized the system for vehicles equipped with GM’s 10-speed transmissions and for the 2025 model year, ensuring smooth, consistent power delivery whether you’re on the highway, at the job site, or off-road.

Reliability Meets Everyday Usability

The system is engineered to handle the rigors of daily use, with ProCharger noting reliability beyond 200,000 miles. Key benefits include:

Substantial torque increases ideal for towing heavy loads

Smooth, predictable power delivery in all conditions

Plug-and-play PCM calibration for seamless integration

Owners don’t have to choose between performance and practicality—this kit provides both.

Bolt-On Installation In An Afternoon

Another standout feature is the ease of installation. Designed for DIY enthusiasts, the kits can be installed in just one afternoon using common hand tools. No major modifications are required, meaning less downtime in the garage and more time enjoying the newfound performance. Each system comes as a complete, turnkey package with all hardware included.

Power With A Purpose

For GM SUV and truck owners, ProCharger’s new supercharger systems deliver more than raw horsepower. They add confidence when merging or passing, muscle for weekend towing trips, and a lot of fun when you put your foot down. By offering OEM-level refinement paired with aftermarket performance, ProCharger continues to set the benchmark for modern, street-ready forced induction.
