ProCharger Revamps Its GM Truck And SUV Supercharger Systems

There’s certainly no shortage of ways to wake up a late-model GM truck, but if your Silverado, Sierra, Tahoe, or Yukon is packing a 5.3- or 6.2-liter V8, boost remains one of the quickest ways to make things considerably more entertaining. Now, ProCharger has overhauled its supercharger systems for 2019-up GM 1500-series trucks and 2021-up SUVs, offering more airflow, easier installation, and, most importantly, more power!

As you might’ve guessed, this isn’t simply a new bracket and a different part number. ProCharger’s redesigned lineup consists of new Stage 1 and Stage 2 configurations capable of delivering power gains of up to 50 percent. Both systems feature a larger air-to-air intercooler, optimized charge tubing, and revised routing designed to improve airflow while reducing charge-air temperatures.

Pick Your Poison

For daily-driven trucks looking for a healthy bump in power, the Stage 1 system uses a shared 6-rib drive. Step up to the Stage 2 package and ProCharger moves the supercharger to a dedicated 8-rib drive designed for combinations chasing considerably more horsepower. Additionally, an available open race bypass valve provides another option for more performance-oriented applications. The idea is pretty simple: make more power efficiently while giving owners enough options to build the system around how they actually use their truck.

That scalability is important because, as most LS and LT enthusiasts know, very few builds stay exactly as originally planned. What starts as “just a little boost” has an annoying habit of eventually becoming injectors, fuel system upgrades, more boost, and a suspicious number of boxes showing up on the front porch. Fortunately, ProCharger has addressed that side of the equation, too.

A More Tuner-Friendly Setup

One of the more interesting changes is the move to a blow-through mass airflow sensor configuration. Instead of its previous location, the MAF is now positioned inside the charge pipe.

It might not be the flashiest change on the parts list, but it should be an important one for anyone planning to push beyond a relatively stock combination. According to ProCharger, relocating the MAF provides aftermarket tuners with greater flexibility as owners add fuel-system, engine, and power upgrades without requiring major changes to the basic supercharger package.

The new systems retain the smooth, linear power delivery associated with ProCharger’s centrifugal superchargers, but the installation itself has also received some attention. Simplified tubing routing and revised hardware are intended to make the system easier to bolt onto the truck using common hand tools, with full-color, step-by-step instructions guiding the process.

Room To Grow

Ultimately, ProCharger appears to be giving late-model GM truck owners something we can always appreciate: options. A Stage 1 combination can add some much-needed attitude to a daily-driven 5.3-liter Silverado, while the Stage 2 system and dedicated 8-rib drive leave considerably more room for owners who know perfectly well that they’re eventually going to turn things up. For enthusiasts who need an emissions-certified option or simply prefer the factory-airbox appearance, ProCharger will also continue offering its existing 50-state-legal system.

Pricing varies depending on the selected supercharger, drive system, finish, and other options, so ProCharger recommends contacting the company or an authorized dealer for a quote.

Whether the goal is waking up the family Tahoe or turning a Silverado into something that has absolutely no business being that quick, ProCharger’s revamped systems leave plenty of room to decide just how rowdy you want to get.
