AEV 4.5" High Capacity Spring Kit for 2007-2018 Wrangler JK (4 Door)

Vendor fitment: 2007-2018 JK Wrangler. Suspension & lifts with 4.5 in lift-height data from the vendor source. Confirm final options and fitment on the vendor page before purchase.

AEV 4.5″ High Capacity Coil Springs are a direct-fit upgrade for vehicles already equipped with an AEV 4.5″ DualSport SC Suspension System. Engineered specifically for overlanders, these frequency-tuned, progressive-rate coil springs are designed to support heavily loaded vehicles without sacrificing ride quality. They provide increased load-carrying capacity while maintaining excellent handling characteristics and off-road articulation. To ensure optimal vehicle dynamics and safety, these springs are sold only as a matched front and rear set. The balance between the front and rear spring rate and frequency is critical to proper handling performance. For this reason, AEV increases the rate.

Question

What lift height is this for?

Suspension lift height

This is a 2.5-3 inch lift-height family. Verify the exact engine, drive side, spring-capacity variant, and loaded vehicle weight before quoting because those choices can change final stance.

Fitment and build notes

Vendor catalog record promoted for browsing. Final fitment, install dependencies, and shopper selection still require review before checkout.

For a lift, the last check is the complete Jeep setup: exact year/model/trim, doors, engine, lift variant, target tire size, wheel width and offset/backspacing, bump stops, flare/fender clearance, gearing, spare support, added bumper/cargo weight, and whether a shop is installing it.
