4″ Suspension Lift Kit for Jeep Wrangler JK

This complete 4″ suspension lift kit for the Jeep Wrangler JK is built using carefully matched ARB / Old Man Emu components. The kit is designed to significantly increase ground clearance, suspension travel and off-road capability while maintaining stability, steering precision and correct suspension geometry.

Product Overview

Lifting a Jeep Wrangler JK by 4 inches requires more than just taller springs. This kit addresses all critical suspension and steering parameters affected by the lift, including caster angle, axle centering, brake line length, sway bar geometry and bump stop positioning. The result is a balanced, reliable suspension system suitable for demanding terrain and daily driving.

Suspension Function and Benefits

The upgraded coil springs provide increased ride height and load handling, while Nitrocharger Plus dampers control suspension movement under heavy loads and rough terrain. Geometry correction components restore proper driveline angles and steering stability, eliminating common issues such as wandering, vibration and uneven tire wear.
