The “Bolt-On” Long Arm Upgrade system from MetalCloak allows you to upgrade your suspension from short arms (short arm) to a full long arm system. As a result, you get much better vehicle control, stable wheelbase throughout the suspension’s operating range, and improved driveshaft angle.
The kit comes complete – it includes all the necessary components needed for the suspension conversion.
