AEV Conversions High-Capacity Coil Springs
AEV Conversions offers high-capacity coil springs in 3 in. and 4.5 in. packages for a variety of Jeep applications. They're a direct-fit upgrade for customers with an AEV DualSport suspension system. Designed with the overlander in mind, these frequency-tuned, progressive rate coil springs provide the increased load carrying capacity necessary for heavily loaded vehicles, while still offering exceptional ride quality, handling and off-road articulation.
These coil springs are only available as a matching set of front and rear springs in order to preserve optimal vehicle handling dynamics. The relative rate/frequency of the front coil springs vs. the rear springs is a crucial part of safe vehicle handling. Because of this, AEV increases the rate/frequency of the front springs in order to maintain an appropriate relationship with the rear springs, across the entire range of rear-biased loading. Order the coil springs recommended for your application.
