These axles come completely assembled and feature hardened steel gears, XVD drives and a billet aluminum housing with removable diff cover. All the exterior housing parts are anodized black with the 12mm steel hexes remaining silver.
These axles are ready for instant installation and retain the stock AR60 axles gear ratio.
