Product Description

The JKS JSPEC113KFA is a complete 3.5" J-Konnect suspension lift system for the 2007-2018 Jeep Wrangler JK Unlimited 4-Door. J-Konnect builds directly on the proven J-Venture platform by adding heavy-duty front and rear J-Link lower control arms, a HD Drag Link Flip Kit, and front and rear track bar support braces - components that take the system from trail-capable to genuinely trail-tough. The J-Link lower control arms are fabricated from 2" x .250-wall DOM tubing, providing a significant strength upgrade over factory stamped steel arms while simultaneously correcting front caster and rear axle wheelbase geometry at lifted height.

Custom-valved FOX 2.0 Adventure Series IFP monotube shocks are tuned side-by-side the JSPEC dual-rate coil springs for immediate, fade-free damping control across all conditions. The HD Drag Link Flip Kit corrects steering angles to restore factory-like handling feel, while track bar support braces protect and reinforce the factory track bar mounting points under sustained off-road stress. JKS2034 Quicker Disconnect sway bar links deliver up to 30% more front axle articulation at the trailhead. Note: 2012-2018 models with the 3.6L Pentastar V6 require the JKS8150 exhaust extension kit for driveshaft clearance at full suspension droop.
