Product Description

The JKS JSPEC124KFA is a complete 3.5" J-Konnect suspension lift system engineered specifically for the 2018-2026 Jeep Wrangler JL 2-Door. As the 2-Door counterpart to the JSPEC123KFA, this kit uses 2-Door-specific JSPEC dual-rate rear coil springs to account for the shorter wheelbase and different weight distribution of the 2-Door platform, while sharing the same proven J-Konnect J-Link lower control arm system. J-Link arms are fabricated from 2" x .250-wall DOM tubing with large OE-style rubber bushings, delivering a dramatic strength upgrade over factory arms while simultaneously correcting front caster and rear axle wheelbase geometry at 3.5" of lift.

Custom-valved FOX 2.0 Adventure Series IFP monotube shocks are tuned alongside the 2-Door-specific spring package for a well-matched, cohesive system. The JKS front adjustable track bar keeps the front axle properly centered, and JKS2033 Quicker Disconnect sway bar links deliver up to 30% more front articulation at the trailhead. Rear extended sway bar links restore proper geometry at the rear. At 3.5" of lift, Sport and Sahara models fit up to 35x12.50 tires, while Rubicon models accommodate 37x12.50. Does not fit 4xe or Rubicon 392 models.
