Boxed trailing arm crossmember built using 3/16" steel.
The Porterbuilt Fully Adjustable Trailing Arm Crossmember is designed to eliminate multiple rear suspension concerns that are presented when lowering the rear of a 1963-1972 truck. It is a direct bolt-in, utilizing the factory mounting locations. It also allows for multiple fore-aft mounting points, along with multiple mounting points for the front trailing arm mounts. The advantage of the multiple fore-aft mounting points is to allow the wheels to be centered in the rear wheel well opening with various drops. The multiple front trailing arm mounting locations allow allowing for adjustments to the instant center, resulting in better performance. It is available for two piece driveshaft configurations and will allow for a 3" exhaust.
