AEV 3″ High Capacity Suspension Kit for 20-up Jeep Gladiator JT (Non-Mojave)

Regular price $1,807.73

AEV first introduced OE-level suspension engineering to the aftermarket over a decade ago. We are still continuing to build on that legacy today, while also broadening our spectrum of suspension performance with the introduction of our DualSport XP Suspension System for the Jeep Gladiator.

The DualSport XP Formula

The Gladiator’s factory suspension (especially on Rubicon) is very soft, lightly damped and has a very low suspension frequency. This “soft tuning” helps the Gladiator drive “less like a truck” and soak up the bumps on the highway decently well but that can also make the handling feel a bit loose and sometimes uncontrolled. This is not a big deal for people who are just driving their Gladiator to and from work every day, but it is definitely not the ideal suspension formula for overland enthusiasts who also need to manage lots of cargo and gear when traveling off the grid.

3” High Capacity Coil Springs are specifically designed for overland enthusiasts who have a fully outfitted vehicle that is also consistently loaded with heavier gear (+400-700 lbs. over the standard load spring), such as modular cargo systems or roof rack/rooftop tent combinations

Note: Exceeding GVWR (Gross Vehicle Weight Rating) and/or RGAWR (Rear Gross Axle Weight Rating) will cause changes in the vehicle’s braking, steering and overall handling performance. AEV never recommends exceeding GVWR/RGAWR.
