You will need:

• For Axle Mounted Servo setup, the optional aluminum servo mount is needed.
• For Chassis Mounted Servo setup, a panhard link is needed (as almost every car has a different setup, we leave this part up to you).
• For Leaf Spring setup, additional optional parts may/may not be needed depending on your setup. Leafs can be mounted directly on top and under the axle. We recommend this.

Optional:

• For Leaf Spring setup, additional optional parts may/may not be needed depending on your setup. Leafs can be mounted directly on top or under the axle. We recommend
  • Steel Leaf Spring Channel w/ Shock Mount for BRX70 / BRX90 Axle (2) BRLC7010
  • Behind-the-axle setup requires: #BRLC7002/A / #BRLC7002/B / #BRLC7010 / #BRASSPD427/N

When you receive the axle:

Make sure all of the screws are tightened properly.

The gear positions are factory setup and should be ready to go. Rotate the drivetrain by hand for physical inspection.

Install spacers accordingly between the center driveshaft and the input shaft to prevent input shaft from unnecessary slop.
