Product Description

The JKS JSPEC134KFA is a complete 3" J-Kontrol suspension lift system for the 2018-2025 Jeep Wrangler JL 2-Door. J-Kontrol builds on the proven J-Venture foundation with one targeted addition: heavy-duty Front Control Arm Correction Brackets fabricated from fully boxed 7GA steel. These brackets lower the frame-side mounting point of the front upper and lower control arms, flattening their operating angles to closely mimic factory suspension geometry at 3" of lift. The result is improved on-road handling, correct caster, and optimized driveline angles - all without replacing the factory control arms. This is the key advantage J-Kontrol holds over the J-Venture system.

Custom-valved FOX 2.0 Adventure Series IFP shocks are tuned alongside 2-Door-specific JSPEC dual-rate coil springs for a fully matched system. A JKS front adjustable track bar and rear track bar bracket keep the front axle properly centered, JKS2033 Quicker Disconnect sway bar links unlock up to 30% more front articulation at the trailhead, and rear extended sway bar links restore proper operating angle at the rear. Note: a rear aftermarket driveshaft is recommended for 2-Door models at this lift height. Does not fit 4xe or Rubicon 392 models.
