Extended Radius Arms & Brackets
Extended Radius Arms gove your vehicle more control.

Extended Radius Arms are made for the true off-road enthusiast. These extended radius arms will give you more control by affording your vehicle better articulation and a sharper turning radius. Because these radius arms are 15 inches longer than the OEM equivalent these radius arms give you more tire clearance and more ground clearance.

Radius Arm Brackets are for mounting your extended radius arms. These brackets can further improve your articulation because the rear brackets employ a pivoting axis mount.

These Radius Arm Kits will fit with most competitors’ lift kits.
