Pitbull Stands Trailer restraint for Slabside GSXR and early Slingshot 88-89 750 (with “box” style swingarm) only. See pic for reference. NOTE: I had Pitbull make the pins for me and in the process they confirmed that TRS required the “wide” frame. The frame works with the normal TRS base plate and clamps. I spent nearly $400 on this set up and used it a handful of times. It’s basically new. This will not work with later years swingarm, confirm before purchase! $300 plus shipping.
