The Jeep Gladiator blends rugged off-road capability with everyday truck utility, but many owners find the factory 3.6L V6 or 3.0L EcoDiesel leaves them wanting more power. Adding a supercharger is one of the most effective ways to transform the driving experience, delivering immediate throttle response and substantial horsepower gains. This expanded guide dives deep into three of the best supercharger brands for the Gladiator: ProCharger, Edelbrock, and Magnuson. We’ll examine their unique technologies, performance characteristics, installation complexity, and reliability to help you choose the right forced induction system for your build.
Why Supercharge a Jeep Gladiator?
Before exploring specific brands, it’s important to understand what a supercharger does for the Gladiator. Unlike turbochargers that rely on exhaust gases, superchargers are belt-driven, providing instant boost without lag. This translates to sharper acceleration from a stop, more passing power on the highway, and improved climbing ability off-road. The Pentastar V6 responds exceptionally well to forced induction, with many kits adding 100 to 180 horsepower at the wheels. For those towing heavy loads or running larger tires, a supercharger also restores the lost power from added weight and rolling resistance. The three brands covered here have established reputations in the Jeep community, each with a distinct engineering approach.
ProCharger: Centrifugal Force for Top-End Power
ProCharger specializes in centrifugal superchargers, which use an impeller spinning at high speeds to compress air. This design is similar to a turbocharger’s compressor wheel but driven by a belt. The result is boost that builds progressively with engine RPM, offering excellent top-end horsepower without overwhelming the drivetrain at low speeds.
Key Technology: Self-Contained Gear Drive
Most ProCharger systems for the Gladiator feature a self-contained oil system, meaning the supercharger does not tap into the engine’s oil supply. This simplifies installation and prevents oil contamination. The gear-drive design is also quieter than some straight-cut gear competitors, and it provides reliable lubrication under high boost conditions.
Performance Gains
With a typical ProCharger kit on the 3.6L V6, owners see around 140-160 horsepower gains at the crankshaft, translating to approximately 400-420 crank horsepower on 93 octane fuel. Torque increases are equally impressive, often exceeding 400 lb-ft. The centrifugal nature means the Gladiator retains a near-stock feel in normal driving, then pulls hard as the RPMs climb above 3,500. This characteristic makes ProCharger a favorite for highway passing and open desert runs.
Installation Complexity
ProCharger kits are designed for DIY-friendly installation. The bracket-based mounting and included intercooler (most kits are air-to-air intercooled) fit within the engine bay without requiring permanent modifications. Average install time is 8-12 hours for an experienced mechanic. The kit includes a pre-calibrated ECU tune, though many owners opt for a custom dyno tune to maximize power safely.
Pros and Cons
- Pros: Strong top-end power, clean installation, self-contained oiling, intercooled for consistent performance, relatively affordable compared to twin-screw options.
- Cons: Less low-end torque than positive-displacement designs, can be noisier at idle (gear whine is present but not excessive), requires good belt alignment to avoid slippage.

Edelbrock: Roots-Style Instant Torque for Off-Road
Edelbrock’s supercharger for the Gladiator employs a Roots-type twin-screw rotor design (actually an Eaton TVS unit under license). Unlike centrifugal, this positive-displacement blower delivers boost immediately from idle, filling the engine with pressurized air right off the line. Edelbrock has a long history of producing high-quality, street-legal performance parts, and their Gladiator kit is CARB EO-approved in many states.
Key Technology: 2300 TVS Rotors
The Edelbrock E-Force system uses Eaton’s fourth-generation TVS (Twin Vortices Series) rotors with a 2300cc displacement. The compact rotor housing fits under the stock hood, and the included air-to-water intercooler sits in the intake manifold to keep charge temperatures low. This design allows the supercharger to maintain peak boost across the entire RPM range, not just at high revs.
Performance Gains
Edelbrock claims a 35-40% increase in horsepower and torque. For a stock 3.6L V6, that equates to roughly 380-400 crank horsepower and 380-400 lb-ft of torque. The key difference is where that power hits: significant boost is available from 2,000 RPM, making the Gladiator feel much stronger off-road and during low-speed rock crawling. The linear, immediate response also makes daily driving more enjoyable without needing to rev out the engine.
Installation Complexity
Edelbrock offers a complete kit with detailed instructions. The supercharger mounts directly to the intake manifold, replacing the factory manifold. Installation takes 10-15 hours and requires mechanical skill, but the kit is designed to be bolt-on. The ECU calibration is provided via a handheld tuner that loads a safe, pre-calibrated map for 91-93 octane fuel. No fuel system upgrades are required at stock boost levels.
Pros and Cons
- Pros: Instant low-end torque, CARB legal (50-state), quiet operation (minimal gear whine), integrated intercooler, maintains factory drivability.
- Cons: Slightly less peak horsepower than centrifugal options, higher cost, heat soak potential in extreme conditions (air-to-water system relies on coolant), requires careful coolant bleeding.

Magnuson: Premium TVS Technology with OEM Fit
Magnuson Superchargers, based in California, has partnered with Eaton to produce some of the most refined positive-displacement systems on the market. Their Heartbeat supercharger for the Jeep Gladiator uses the same Eaton TVS 2300 rotor pack as Edelbrock but with a different housing, intercooler layout, and tuning philosophy. Magnuson is known for exceptional build quality and comprehensive vehicle integration.
Key Technology: Heartbeat Intercooled System
The Magnuson Heartbeat system features an integrated air-to-water intercooler located inside the intake manifold castings. This design keeps the intake air path short and efficient, reducing the overall volume that needs to be pressurized for fast throttle response. The supercharger also uses a bypass valve that opens at cruise and idle to improve fuel economy and reduce parasitic drag. The housing is cast from 356 aluminum and features high-flow porting.
Performance Gains
Magnuson reports 40-50% horsepower gains on their Gladiator kit, with typical numbers around 410-430 crank horsepower and similar torque figures. Like Edelbrock, the positive-displacement design delivers boost from just off-idle, but Magnuson’s tuning often emphasizes a broader torque curve, with peak torque arriving lower in the RPM range. The system is fully compatible with manual and automatic transmissions, though clutch upgrades may be needed for manuals under hard use.
Installation Complexity
Magnuson kits are considered slightly more involved than Edelbrock due to the need to relocate the coolant expansion tank and modify the factory airbox. The kit includes a preloaded calibration via a handheld programmer, and Magnuson provides detailed step-by-step video instructions. Many owners report an install time of 12-16 hours. The supercharger bolts onto the engine without needing to drop the oil pan or remove the front axle, a big plus for those working in a home garage.
Pros and Cons
- Pros: Excellent low- and mid-range torque, premium OEM-grade fit and finish, robust intercooler system, impressive build quality, long-term reliability.
- Cons: Higher price point than ProCharger, larger overall dimensions can make spark plug access more difficult, requires a more thorough installation procedure, slight whine under boost (audible but not intrusive).

Installation and Tuning Considerations
Regardless of brand, several factors are critical to a successful supercharger installation on the Gladiator.
Fuel System
The factory fuel pump and injectors can handle moderate boost, but for kits targeting 7+ PSI or using E85, upgrading to 35 lb/hr injectors or a higher-flow pump is recommended. ProCharger and Magnuson kits include injectors in some packages; always verify what’s included.
Cooling System
Intercooled systems (all three brands offer intercooled kits) reduce intake air temperature and prevent detonation. For true off-road use with heavy load, consider upgrading the radiator and adding an auxiliary coolant pump for the supercharger intercooler loop. Heat soak can be an issue with air-to-water systems during extended low-speed crawling.
Drivetrain Upgrades
The ZF 8HP 8-speed automatic transmission in the Gladiator is robust, but high torque levels require proper fluid cooling. For manual 6-speed Gladiators, a stronger clutch is essential if you plan to use the supercharger’s full potential. Also, consider upgrading the driveshaft and axle shafts if you run 37-inch tires or larger.
Tuning and Emissions
All three brands provide a safe, pre-loaded calibration. For maximum power and reliability, a custom tune from a reputable shop (e.g., DiabloSport or HP Tuners) is recommended. If you live in California or other states with strict smog check programs, look for a CARB EO-numbered kit. Edelbrock and Magnuson offer CARB-compliant versions for the Gladiator; ProCharger does not currently have CARB approval for the 3.6L.
Real-World Owner Experiences
Online forums like Jeep Gladiator Forum and Reddit’s r/JeepGladiator contain extensive owner reviews. ProCharger owners frequently mention the addictive pull above 4,000 RPM and ease of installation. Edelbrock owners praise the seamless power delivery and quiet operation. Magnuson owners highlight the build quality and torque that makes the Gladiator feel like a diesel at low RPM. Common advice: if you primarily drive on the road and want maximum top-end, go ProCharger. For off-road prowess and towing, choose Edelbrock or Magnuson.
