Did they tell you How keeping it in reverser relieve the stiffness? It's mechanical, Working it and wearing it in would be the only way that it will relieve the stiffness..Short throw is a nice mod. I put a Hinson in my Z51. It uses the stock shifter knob so it’s stealth. Very stiff new but has loosened a little over time . Hinson said to keep it in reverse when parked to help relieve the stiffness.
That would be MY ignorance. Brand new it was very hard to get it into reverse (also 6 & 7). Hinson told me it needed to be driven and in time would be less stiff. They recommended putting it into reverse when parked to speed this along.Excused my ignorance, but which springs?
