"Fabtech Uniball upper control arms are perfect for the agressive, off-road driver. They replace your flimsy factory arms that tend to flex and have ball joint failure under severe use and they work with most aftermarket suspension systems. Fabtech uses 4130 Chromoly tubing for their arms, the same material used for Trophy truck fabrication. 1"" ID stainless steel American made Uniball bearings are indexed to the arms and will allow for increased travel if you have the Fabtech Dirt Logic coilover shocks. These Uniball upper control arm kits are designed as direct replacements for factory control arms and will not require any added drilling or cutting to get them installed. They work great with both stock or aftermarket suspensions to give you more strength and reliability off-road. Order your Fabtech Uniball upper control arms and make sure you have one less thing to worry about breaking down on your next adventure! | Fabtech Uniball Replacement Upper Control Arms FTS21127"
