Magnuson’s all-new, fully redesigned Jeep 3.6L V6 supercharger system is designed exclusively for 2018-2020 (2021 manual) Wrangler (JL) and Gladiator (JT) vehicles. Magnuson’s engineers have created a truly remarkable product by carefully matching a TVS1900 supercharger to operate in its peak thermal efficiency zone for almost the entire engine duty cycle. The result is super low inlet air temps for massive gains in horsepower and torque, producing V8 levels of performance at an extremely affordable price.

In stock trim with no other system modifications, this kit provides an AMAZING 440hp AND 380 ft-lbs OF TORQUE at the crank, equivalent to ~372 REAR WHEEL HP. That’s an incredible 59% more power than the stock V6.

At 440HP, the new Magnuson Jeep JL/JT supercharger kit also creates 22% MORE HORSEPOWER THAN A 5.7L HEMI V8. At the lowest price on the market, the kit is significantly more affordable than a Hemi V8 swap, leaving more cash for other vehicle upgrades. The install can also be done in a day with minimal vehicle downtime (note that a couple of extra days are required to send ECU out for unlock/re-flash) and is easy to convert back to stock – no cutting or welding required, and no need to swap transmission/cooling/exhaust/AC/wiring systems.

Magnuson only use the highest quality components in our supercharger kits. Everything you need to supercharger your Jeep is included, right down to detailed step-by-step installation instructions. Order yours today and unleash the power of a Magnuson Supercharged Jeep!
