TeraFlex Suspension 1864402 4.5 Inch Front Lift Coil Spring Pair for Jeep Wrangler JL 2-Door

The TeraFlex 1864402 front lift coil spring pair delivers 4.5 inches of lift for 2018+ Jeep Wrangler JL 2-door models. These precision-engineered progressive dual-rate coil springs provide exceptional performance both on the highway and off-road through extensive rate tuning and dynamic balance optimization.

Progressive Dual-Rate Design:

The innovative dual-rate design delivers consistent performance during normal street driving with predictable handling characteristics similar to linear rate springs. When the axle begins to droop during off-road articulation, the softer upper section of the coil spring unwinds to maximize flex and maintain spring retention for superior off-road capability.

Key Features:

• Progressive dual-rate coil spring design for optimal on-road and off-road performance
• 4.5 inch lift height for aggressive tire clearance and improved ground clearance
• Engineered with precise front-to-rear and side-to-side load bias for balanced handling
• Enhanced droop travel for maximum suspension articulation
• Designed to pair with Falcon Performance Shocks for superior compression and rebound control
• Application-specific engineering for JL 2-door chassis geometry

What's Included:

• Two (2) front lift coil springs

TeraFlex Lift Coil Springs are recommended for use with Falcon Performance Shocks, as both components have been engineered together to optimize vehicle stability and ride quality across all driving conditions.
