I have a factory looking lowering link for the rear banshee shock. It is about 4.1 inches long so it is about an inch longer than the stock one. It should lower you banshee by 1 to 2 inches in the rear. This will flatten out the rear of the bike so it launches harder. Any time you add a long swinger to the banshee, the rear end is too high.
Only $25 shipped. PM me if you want it.
