TeraFlex Suspension 1864400 4.5 Inch Front Lift Coil Spring Pair JL Wrangler 4-Door

TeraFlex 4.5-inch lift coil springs are precision-engineered for 2018+ Jeep Wrangler JL Unlimited (4-door) models, delivering exceptional highway handling and off-road performance. Extensive rate tuning and dynamic balance optimization between front/rear and side-to-side load bias ensure superior vehicle stability in all driving conditions.

Progressive Dual-Rate Design:

The front coil springs feature an innovative progressive dual-rate design that adapts to driving conditions. During normal street driving, they perform like linear-rate springs with consistent, predictable handling. When the axle begins to droop during off-road articulation, the softer upper section unwinds to maximize suspension flex and spring retention for superior wheel travel.

Key Features:

• 4.5-inch lift height for increased ground clearance
• Progressive dual-rate front coil springs for optimal on/off-road performance
• Engineered for dynamic balance and load bias optimization
• Enhanced articulation with softer upper coil section for maximum droop travel
• Designed to pair with Falcon Performance Shocks for superior compression and rebound control
• Sold as a pair (front axle set)

Application:

• 2018+ Jeep Wrangler JL Unlimited (4-door only)

For best results, TeraFlex recommends pairing these lift coil springs with Falcon Performance Shocks, as both components have been co-engineered to optimize compression, rebound, and overall vehicle stability.
