Step 2 - Determine Required Ball Height

Determine the proper ball height by leveling the trailer and measuring 

from the bottom of the trailer tongue to the ground, see below.

Find the hole closest to that measurement on the adjustable shank (#1). 

The dual ball (#2) will be centered on that hole.

Step 3 - Attach the Dual Ball

Based on the determined ball height, slide the dual ball mount 

onto the shank and align with the proper hole locations. 
Angle the mount slightly upwards and press in toward the shank. 

Insert a pin (#3) into the top mount hole first. To pin the bottom 

mount hole, apply downward force to the mount, and slide 

the second pin into place.

Note: 

The highest mounting position will require the bottom 

pin to be installed first with the mount angled downward. 

Then, apply force upwards to install the second pin. 
Secure all pins with the clips included with your Rebellion

 XD.

WARNING

 

The pins included with your Rebellion

 XD shank are specifically 

engineered for this system. If replacement pins are needed, they 

must be replaced with original factory mount pins (CURT# 45959).

Before you Begin

The Rebellion

 XD dual ball accessory has a built-in anti-rattle feature 

located in the channel on the backside to keep your towing system quiet. 

See the recommended assembly instructions for optimal performance.

Step 1 - Insert into the Trailer Hitch

Begin by installing the shank (sold separately) into the trailer hitch 

receiver and secure it with a hitch pin and clip (sold separately).
