The GForce Engineering G2 Outlaw Axle Kit is the ultimate high-performance drivetrain upgrade for the 2018-2021 Jeep Grand Cherokee Trackhawk 6.2L Supercharged (WK2) and 2021-2026 Dodge Durango Hellcat.

These premium rear axles feature advanced engineering with upgraded 31-spline severe-duty CV joints, larger-diameter 31-spline axle bars, 32-spline inner stubs, and 35-spline outer stubs.

Upgrading your axles is one of the highest-impact modifications for trucks and off-road vehicles that regularly see hard launches, deep mud, rock crawling, or towing at the limits. Aftermarket axle shafts are manufactured from higher-grade steel than OEM units, delivering greater torsional strength and resistance to fatigue failures that stock shafts cannot handle under sustained abuse. Popular Upgrades Chromoly front and rear axle shafts are the go-to upgrade for lifted trucks and Jeep builds running larger tires with increased leverage on the driveline. Locking differentials paired with upgraded axles make a complete traction system for serious off-road builds. Heavy-duty CV axles for both front-wheel-drive and all-wheel-drive platforms handle the added stress of lowered suspension geometry and high-horsepower applications. When should I upgrade my axle shafts? Upgrade your axle shafts when adding larger tires, significantly increasing engine power, installing a locking differenti...

Dodge Durango SRT Hellcat Parts & Accessories

The Dodge Durango SRT Hellcat is a 710-horsepower, three-row SUV with a 6.2L supercharged V8 — and it responds extremely well to bolt-on upgrades. The Hellcat's combination of family SUV packaging with genuine supercar performance makes it a unique build platform, and the parts catalog reflects that unusual combination. Popular Upgrades Cold air intake systems from Legmaker and Corsa are among the first modifications Durango Hellcat owners make, improving airflow past the 2.4L supercharger. Borla's ATAK and Corsa's Xtreme cat-back systems deliver a dramatic transformation in exhaust sound for a vehicle that otherwise sounds surprisingly subdued from the factory. Coilovers from KW and performance lowering springs from Eibach sharpen handling in a platform that weighs over 5,400 lbs. What exhaust fits the Durango SRT Hellcat? Borla and Corsa both produce dedicated cat-back systems for the Durango Hellcat's 6.2L supercharged V8. These are fitment-specific and will not interchange with ...
