Other lift heights posted are estimated based off calculated vehicle weight values. Actual lift height achieved may vary from model to model. 

Features:

  • Rear lift coils for 2-Door and 4-Door Jeep JK Wranglers
  • Synergy coils offer excellent off road performance while preserving ride quality
  • Progressively wound; keeps spring from coming unbound at suspension droop*
  • Progressively wound spring eliminates annoying spring clanking found on most suspension kits*
  • Feature frequency balanced and tuned spring rates to maximize suspension performance on and off road
  • Suspension components feature an abrasion-resistant black powder coat finish for maximum durability and corrosion resistance
  • Springs are designed to give the advertised amount of lift with use of aftermarket rear bumpers & tire carriers.
  • Sold in Pairs

Note: Springs retain the factory rake of the vehicle where the rear is higher than the front. Vehicle should sit level when loaded. Request one size shorter rear springs to level the vehicle out when unloaded

  • When using 35" tires 3" Tall Bump Stop Spacers are required
  • When using 37" tires 4" Tall Bump Stop Spacers are required
