TeraFlex 1873001 3.5" Front Lift Coil Spring Pair for Jeep Gladiator JT Diesel

The TeraFlex 1873001 front lift coil springs are precision-engineered specifically for Jeep Gladiator JT models equipped with the 3.0L EcoDiesel V6 engine. These progressive dual-rate coil springs deliver 3.5 inches of lift height while providing exceptional on-road handling and off-road performance.

Progressive Dual-Rate Design:

• Provides consistent performance and predictable handling during normal street driving, similar to a linear rate spring
• Softer sprung upper section unwinds during axle droop for maximum flex and spring retention
• Extensive rate tuning ensures dynamic balance between front and rear suspension
• Optimized side-to-side load bias for superior vehicle stability

Construction and Durability:

• Shot peened to reduce spring sag and fatigue while extending service life
• Powder coated finish provides superior protection against the elements
• Limited lifetime warranty against defects

Important Installation Notes:

• EcoDiesel models require the 1" Front Coil Spring Spacer Adjustment Kit (TeraFlex #1155100, sold separately) to properly level the vehicle
• Pairs perfectly with Falcon Performance Shocks, which are specifically engineered to work with TeraFlex lift coil springs for optimal compression and rebound
• Advertised lift height may vary based on additional equipment such as winches, aftermarket bumpers, or loaded cargo weight

Sold as a pair for complete front axle installation. Professional installation recommended.
