At the rear of the chassis, you'll notice we've changed the way our tubular crossmembers attach to the rails. We no longer weld the crossmembers to the inside of the chassis rails, only. The two 1 3/4-inch X .120-inch wall D.O.M. tubular crossmembers that actually go all the way through the chassis and are welded on the inside-and-the outside of the chassis rails. They are the forward 4-link crossmember and the crossmember over the rearend for the antisway bar. This allowed us to hide the rear antisway bar inside the tubular crossmember over the rearend. The new through-frame design adds additional strength to the forward 4-link crossmember, where the torque is transferred to the tires and the road. This is where we changed our design. We now have the super strong center box-tube X-member connected to the forward 4-link thru-frame crossmember so you can put the pedal to the metal with a smile on your face! Notice the disc brakes at the rear are the optional Explorer solid rotor type with parking brake shoes inside the rotor. The arm coming out of side of the frame rail just above the rotor is connected to the ¾-inch diameter thru-frame antisway bar.
We also have a new Panhard rod design behind the rearend housing. The new longer and lower Panhard rod is now parallel with the axle housing which lowers the actual roll-center of the chassis. We call this our Low Roll-Center Panhard bar.
Your options here are our Diagonal Link or regular Panhard bar over the top of the (rearend) housing. We made our Low Roll-Center bar a standard feature on our tri-five chassis.
