These arms fit 4th gen trucks without radius arms, so the 2010 to 2013 Ram 2500 4x4 models and the 2010 to 2012 Ram 3500 4x4 models. These allow 1.5" extra tire clearance for those who are running factory wheels, or wheels with high backspacing (more than 4.5"), or those with wide tires. If you are having problems with your tires rubbing the control arms you have now, these are a great fix for that problem. We have not found a wheel or tire combination that does rub with these short arms, so they should be a "cure all" regardless of your setup.
These arms are made to order so please note the build times posted above. All arms are made to push the axle 1/2" forward of the stock location for more tire clearance and better suspension and steering geometry. They are powdercoated gloss black.
