TeraFlex 1863000 3.5 Inch Front Lift Coil Spring Pair for Jeep Wrangler JL 4-Door

TeraFlex JL Lift Coil Springs are precision-engineered for the 2018+ Jeep Wrangler JL Unlimited 4-door, delivering exceptional highway handling and off-road performance. These coil springs feature extensive rate tuning and dynamic balance between front and rear, as well as side-to-side load bias for superior driving characteristics.

Progressive Dual-Rate Design:

The front coil springs utilize a progressive dual-rate design that provides optimal performance both on and off-road. During normal street driving, these springs deliver consistent performance and predictable handling similar to a linear rate spring. When the axle begins to droop during off-road articulation, the softer upper section of the coil spring unwinds to maximize suspension flex and spring retention.

Key Features:

• 3.5 inch lift height for improved ground clearance
• Progressive dual-rate spring design for versatile performance
• Engineered specifically for JL Wrangler Unlimited 4-door models
• Enhanced compression and rebound characteristics
• Optimized load bias for balanced handling
• Maximum flex capability for off-road articulation

Includes: Pair of front 3.5 inch lift coil springs (2 springs)

For superior performance, TeraFlex recommends pairing these lift coil springs with Falcon Performance Shocks, as they have been co-engineered to improve both compression and rebound for optimal vehicle stability.
