AEV 3in High Capacity Coil Springs

AEV 3″ High Capacity Coil Springs are a direct fit upgrade for 4-Door JL Wrangler customers with an AEV 2.5″ DualSport Suspension System already installed on their vehicle. Developed with the true overland enthusiast in mind, these frequency-tuned, progressive rate coil springs provide the increased load carrying capacity necessary for heavily loaded vehicles, while still offering the exceptional ride quality, handling and off-road articulation that AEV is known for.

While these coil springs will work for a lighter weight vehicle, customers should be aware that it will sit higher than advertised and have a slightly stiffer ride – not excessively harsh or intolerable, but also not nearly as pleasant for daily use as a vehicle within our target weight range.

AEV High Capacity coil springs are engine specific and only sold as a complete set of front/rear springs in order to preserve the optimal vehicle handling dynamics that our DualSport suspensions provide.

Note: AEV High Capacity Coil Springs are NOT compatible with 2-Door Wrangler models. 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.

A: No. Stock shocks are not long enough for a 3” lift. You’ll need to use longer aftermarket shocks, such as AEV-tuned Bilstein 5100 or XP8100 shocks, which are designed to complement these springs.

A: At 3” of lift, you should consider supporting components like geometry correction brackets, extended sway bar links, bump stop extensions, and possibly adjustable control arms or track bars to restore proper suspension geometry.

A: Yes. They provide greater ground clearance, better suspension travel, and the progressive-rate design ensures good ride quality both on and off the road.
