AEV JK 4dr 4.5" High Capacity Spring Kit

AEV 4.
5″ High Capacity Coil Springs are a direct fit upgrade for customers with an AEV 4.
5″ DualSport SC 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.
