To replace a damaged AKA tube from an existing BOSS system order these. We include one extreme 1 3/8" diameter x 48" long Aka tube and one Extreme Ama (with plastic saddle) in color of your choice. The extreme designation means we have added tubing and doubled the strength of the tube. Price is for one side & includes domestic shipping.Fast pin included. You will need to drill a 1/4" hole to mount these to your existing cross tube. BSD is not making the old style strut system aka. We also recommend upgrading the whole lower boss on any sail rig over 10 years old. The failure rate is high for the older sail rigs with out the new extreme "doubler" tubes.
