To address a factory weld failure for some 2007-2009 Jeep JK Wranglers, Superlift has come out with two options to fix the potential weak link. The problem area lies where the OE rear track bar bracket attaches to the axle housing, where a weld failure would lead to detachment. The first option offered by Superlift is to utilize a weld-on brace that will hold the OE bracket to the housing axle. The weld-on brace is included with every Superlift 4-in. JK lift package and every Black Diamond 3-in. JK system. The brace can also be used on a stock JK Wrangler, or on a lifted JK that will be reset to the factory height.
The second option is to use Superlift's optional bolt-on track bar bracket with an integrated brace. This option is well-suited for JK owners who do no want to weld, but may not be as cost-effective as the weld-on solution. Although Superlift has said that both braces should be compatible with all brands of suspension lifts ranging from 2-in. to 4-in., all parts should be fit-checked for verification.
