Description
The TeraFlex JK 4dr: 4" Coil Spring Lift Kit w/ Track Bar includes just the basic lift components only and doesn't have the drivability of a full suspension system. Requires longer preset or adjustable control arms to correct suspension geometry. An adjustable rear track bar is recommended.
Notes
- Does NOT include shocks.
- We recommend Falcon Performance Shocks or TeraFlex 9550 VSS Twin-Tube Shocks. These are the only shock absorbers engineered to work with TeraFlex lift coil springs to improve both compression and rebound for optimal vehicle stability.
- Shocks are available separately.
- Lift Height: 4"
- Max Tire Diameter: 37"
- Caster correction required - NOT INCLUDED.
- Proper suspension geometry ensures all stability controls function w/in factory parameters.
- The following components are recommended to optimize caster and pinion angles and restore factory steering and suspension geometry: adjustable 8-Arm Short Control Arm Kit (Alpine: # 1415610 & Alpine IR: # 1415611), or adjustable 8-Arm Long Control Arm & Bracket Kit (Alpine: # 1315010 & Alpine IR: # 1315011), and/or HD Forged Adjustable Front Track Bar (# 1753418), and/or HD Forged Adjustable Rear Track Bar (# 1754418).
- Requires aftermarket wheels w/ 4.75" backspacing or less - or Offset Wheel Adapters (# 1055000) for stock wheels - NOT INCLUDED.
- 2012-2018 JK Wrangler/Unlimited models require Exhaust Spacers (# 2610000) or other exhaust modification for proper driveshaft clearance if front extended shock length is greater than 24.5".
- We highly recommend driveshaft modifications. See the TeraFlex Rzeppa High-Angle CV Kit (# 1744014).

- Requires longer shocks (NOT INCLUDED in base kit) - we recommend Falcon Performance SP2 Mode Adjust Shocks or TeraFlex 9550 VSS Twin-Tube Shocks (# 1545200).
