Suspension Arms & Components
Suspension arms and components include the control arms, camber adjustment arms, traction bars, toe arms, and tie rod assemblies that define suspension geometry and connect the wheel hubs to the vehicle chassis. Quality suspension arm upgrades correct geometry on modified vehicles and replace worn factory components to restore precise handling. Popular Suspension Arm Upgrades Popular suspension arm upgrades include adjustable rear camber arm kits for correcting camber on lowered vehicles, rear traction arm replacement kits, tubular front lower control arms for improved geometry and clearance, adjustable toe arm kits, upgraded tie rod ends with improved ball joint construction, and full rear suspension arm upgrade packages for popular sport and performance platforms. Why do lowered vehicles need adjustable suspension arms? Lowering a vehicle changes the geometry of the suspension arms relative to the factory-intended range of motion, introducing excessive negative camber in the rear ...
