Made my trans swap from a TH 350 to a TH 400 a snap. Easy to install if you have the right Bracket on you carbuator for a kick down cable . Need to run a 12volt power source to the switch and a wire to your Th 400 trans . Nice because it is some what adjustable. 80% full throttle vs 90% full throttle.
4 pieces Saddlebag Lid Wear Plates Strike Plates for Harley 90962-93 H-D
Product fit like the original, I have not put a lot of miles on it yet so I can't say if it will last as long as the original but time will tell and at half the cost it is a bargain
