The Racken Upgrade Kit with NO DSM (Double Swivel Mount) allows you to upgrade the original Racken Rest to mount the extra U Bolt and Medial Tube of the latest Racken Rest II providing the Original Racken already has a Double Swivel Mount already fitted. If your Racken DOES NOT have a DSM fitted, do NOT buy this upgrade Kit, you will need the one with a DSM.
This opens up the option of the fitting up of the Balance Strut Kit and or the Lean-To Pad and Brace.
