# T-Arm Insertion to Bottom Chassis ## Video {% embed url="" %} ## Bill of materials {% embed url="" %} ## Procedure 1. Insert the rubber edge trim into the inner edge of the opening in the Bottom Chassis.

The addition of the rubber trim ensures a tight fit when the torsion box is inserted.

2. Angle the Suspension Arm at a 45°'ish angle and insert the exposed portion of the axle first, ensuring it sits right above the rubber trim as so:

3. Pivoting on the rubber trim, turn the suspension arm to a straight angle while pushing inwards.

5. Repeat the above steps with the remaining suspension arms. ## Assembly notes {% hint style="warning" %} NOTE that you will need to leave at least ONE Torsion arm assembly temporarily disconnected in order to get the 220-001 cross braces in place. This is needed, as the opening in the chassis is used to angle the cross braces into place. {% endhint %}
