The Skyjacker JL 4XE non-rub suspension package with ADX remote-reservoir shocks and dual-rate long-travel coil springs is designed to improve off-road articulation and ride control. Skyjacker’s ADX 2.0 monotube shocks use IFP technology and a remote reservoir to reduce cavitation and improve heat dissipation, while dual-rate coils balance comfort and full-travel stability. Components aim to maintain proper suspension geometry and ESC compatibility.
