AEV JK 4.5" High Capacity Coil Springs
Call for Availability
AEV’s 4.5″ High Capacity Coil Springs are a direct fit upgrade for customers with an AEV 4.5″ DualSport SC/RS Suspension System.
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.
