TeraFlex 1402030 4.5" Coil Spring Base Lift Kit JL 4-Door 392

The TeraFlex 1402030 is a 4.5" Coil Spring Base Lift Kit engineered for the Jeep Wrangler JL 4-Door with the 392 engine. This kit provides the essential lift components needed to raise your Jeep 4.5 inches for increased ground clearance, accommodating larger tires and a more aggressive stance without sacrificing everyday drivability.

Key Features:

• 4.5" of lift — significant ground clearance gain over stock for improved off-road capability
• Front and rear lift coil springs — corner-specific rate tuning for proper load balance and ride quality
• Front and rear track bar brackets — improve steering response and center the axles to optimize vehicle roll center
• Extended sway bar end links — maintain stability and reduce body roll at lift height
• Bump stop extensions — protect the vehicle from hard suspension bottoming during off-road use
• Bolt-on installation — no cutting or welding required
• 392-specific fitment — components sized and rated for the heavier 392 Hemi powertrain

Important Notes:

• This is a base lift kit only — shocks are not included. TeraFlex 9550 VSS Twin-Tube Shocks or Falcon Performance Shocks are recommended and sold separately.
• Caster correction components (Front Control Arm Sport Brackets or Alpine IR Control Arms) and HD Forged Adjustable Track Bars are not included and are required to fully correct suspension geometry.
• Requires aftermarket wheels with 4.75" backspacing or less, or offset wheel adapters for stock wheels.
• Post-installation alignment is strongly recommended.

TeraFlex suspension systems are backed by a limited lifetime warranty covering defects in materials and workmanship, making this a confident long-term investment in your Jeep's off-road performance.
