This Stage 2 system is configured for more upfitted Raptors that have constant load in the bed, with triple-rate rear coil springs tailored to deliver a 1" rear lift on Raptors with approximately 300lbs of additional rear weight. ICON-engineered droop, ride, and overload rates ensure optimal suspension performance across a variety of driving conditions. The performance ride rate balances comfort and compliance, while the overload rate enhances load handling and bottom-out resistance. For maximum articulation and efficiency, the rear coils feature a tapered wire design, providing exceptional droop travel and off-road capability.
