Looking to add strength to your stock Axial AR60 axle housings?  These machined stainless steel strength tubes slide into the stock housing and provide the additional stiffness needed when running larger tires or brushless setups.  These tubes weight a total of 33g.

Note: If adding these to a complete truck, you will need to purchase 2 sets.  You will need to trim down the circled areas (in 2nd pic) for your rear axle to slide through these tubes.
