Synergy Jeep JKU 4-Door Stage 1.5 Suspension System, 3" Lift

  • Sale
  • Regular price $1,325.00

The Stage 1.5 System increases the lift height to 3" with our 3" Progressive Coil Springs and takes full advantage of our Raised Rear Track Bar Bracket and Front Steering Correction Kit (8011) for optimal steering and suspension geometry. With the steering corrected for 3" of lift, this system will drive as good, if not better, than stock. This system will fit 35" tires with stock fenders or 37" tires with high fenders.

  • Front and rear track bar relocation brackets raise track bar mounting positions increasing suspension roll center heights which improves handling on and off road
