Product Description

The JKS J-Kontrol Main Box Kit (part JSPEC1310) is an essential building-block component of JKS's J-Kontrol suspension system for the 2018-2024 Jeep Wrangler JL. J-Kontrol improves ground clearance and off-road capability while retaining your OE control arms, stepping up the rest of your suspension for a true bolt-on upgrade.

Included front control arm correction brackets further enhance on-road handling by flattening out the control arm angle to more closely mimic factory geometry while correcting caster. Combined with JKS's dual-rate coil springs, adjustable front track bar, and Quicker Disconnect sway bar links, this system delivers solid performance for daily driving, beach cruising, or regular trail use.

This component is used within JKS's complete J-Kontrol suspension system kits for the JL Wrangler (2-door and 4-door) and is backed by JKS's limited lifetime warranty.
