Geometry Correction Brackets For JL Wrangler & JT Gladiator

JL & Gladiator Geometry Correction Brackets


PN: NJL20400AA

Out of stock

AEV’s Geometry Correction Brackets correct the front end control arm geometry on vehicles with 2-3.5” of suspension lift. These brackets improve ride quality by eliminating front axle ‘precession’ caused by uncorrected suspension lift geometry.  The corrected motion allows the front tires to move up and rearward (as they did on the stock vehicle) in response to a bump rather than trying to ‘lunge’ over it.  Additionally, they dramatically reduce front-end ‘dive’ during hard braking by relocating the ‘virtual instant center’ of the front suspension.  They also provide alignment correction for proper tracking by restoring caster angle without the need for cam bolts or different/adjustable arms, plus a slight reduction in maximum front driveshaft angle during suspension travel.

These heavy duty Geometry Correction Brackets are included with AEV’s 2.5” DualSport RT Suspensions and can be added as an option to AEV’s 2” Spacer Lift, in addition to other brand suspension systems that also retain the OE front control arms.
