Product Description

The JKS JSPEC145KFA is a complete 3" J-Konnect suspension lift system engineered specifically for the 2018-2026 Jeep Wrangler JL 2-Door. As the 2-Door J-Konnect entry for the JL platform, it delivers the defining J-Konnect upgrade over J-Venture - front and rear J-Link lower control arms fabricated from 2" x .250-wall DOM tubing - packaged with 2-Door-specific JSPEC dual-rate coil springs tuned for the lighter, shorter-wheelbase 2-Door JL at 3" of lift. J-Link arms provide a dramatic strength advantage over factory lower control arms while simultaneously correcting front caster and rear axle wheelbase geometry, with OE-style rubber bushings at both ends keeping on-road NVH well-controlled.

Custom-valved FOX 2.0 Adventure Series IFP shocks are matched to the 2-Door spring package for a cohesive, precisely tuned system. A JKS front adjustable track bar and rear track bar bracket keep 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 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. For the HD rate coil spring variant, see JSPEC146KFA.
