Stinger exchanges used to be free for the original owner. I get the Hensley newsletter and it recently had the program listed but nothing was mentioned anymore about it having to be the original registered owner. Maybe it allows exchanges for everyone now or maybe the previous owner can help you out. Call Hensley and see 1-800-410-6580.
Normally you pay a deposit and the shipping and they send you a new one. The deposit is refunded when you return yours.
I got mine used too and had to swap the stinger. A local dealer here sells them for $140 plus my trade. I now need to swap again but may try the Hensley route first, unless anybody here wants to swap a straight stinger for a 2" drop?
