As vehicles become more and more sophisticated, adding lift and suspension modifications affect your vehicle's internal computer and its Electronic Stabilty Programming (ESP). AEV is commited to developing electronic modules that correct errors and compensate for the customizations you've made to your vehicle.

Electronic Geometery Recalibration (EGR) Module for 2005-08 Jeep WK/XK

THE AEV EGR Module was created for 2005-08 Grand Cherokee (WK) and Commander (XK) owners who have installed the Superlift 4" Suspension System (Part #'s K829 & K829R). Without the AEV EGR Module, this suspension modification creates errors in a vehicles ESP system. This module corrects the vast majority of those errors.

• Corrects 95% of ESP errors
• 1 year warranty

• Enable/Disable reverse mirror tilt
• Gear ratio correction (3.73 or 4.10)
