Product Resources
Features & Product Details
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.
Frequently Asked Questions (FAQ's)
Q: Are these springs compatible with the factory shocks?
A: Factory shocks are not long enough for a 3" lift and should be replaced with longer-travel shocks such as the AEV/Bilstein XP8100 or 5100 series tuned for 3" lift applications.
Q: Will these springs help with overlanding loads or towing?A: Yes. These heavy-duty springs are ideal for overlanding rigs that carry roof tents, gear, armor, or trailers. They help maintain proper ride height and reduce squat under load.
Q: Do these springs affect articulation or ride quality?A: The progressive-rate design allows for good on-road comfort and excellent off-road flex, especially when paired with the proper bump stops and shocks.
