Skyjacker JLUR453FDR 4.5-Inch Front Dual-Rate Long-Travel Coil Springs for 2021-2022 Jeep Wrangler

Upgrade the front suspension of your 2021 or 2022 Jeep Wrangler with Skyjacker JLUR453FDR 4.5-inch front dual-rate long-travel coil springs. Engineered for demanding off-road use, these precision-designed springs improve suspension articulation while maintaining controlled, comfortable street manners. The progressive two-stage design transitions from a compliant Flex Rate to a firmer Ride Rate for balanced performance across changing terrain and driving conditions.
During full suspension droop, the Flex Rate stage allows the coils to flex and expand while helping keep the springs seated in the upper coil mounts. This design supports tire contact with uneven terrain and helps maximize suspension travel and articulation. As the suspension compresses beyond the Flex Rate stage, the Ride Rate engages to provide the additional support needed for improved handling and stability. The result is capable off-road performance without sacrificing everyday drivability.
Skyjacker manufactures each spring from durable 5160H chromium alloy steel and uses high-velocity shot peening to compress the surface and increase tensile strength. A presetting process compresses each spring to solid height, helping relieve internal stress and reduce the potential for sagging over time. Every coil spring is cycle tested for quality assurance, then finished with a baked-on powder coating that provides a durable barrier against corrosion. This component-box package is designed for Jeep Wrangler applications requiring a 4.5-inch front lift and extended suspension capability.
