Put my kit on the sled once the shock was revalved by my dealer. One problems is with the two back springs; the inner coil rubs hard on the idler wheels on both sides. Also, I had to remove the two lock-type washers that keep the triangle spring adjusters so the spring bar could sit correctly on it, although, I think it is still not correct. The triangle adjusters are flush with the end of the bar they mount on and the idler wheels still rub. Maybe this is where my top speed is suffering. I will need to shave some of the wheel hub off to eliminate the spring rubbing. I love what the kit does for riding; but, I think more time should have been put in on the fitment of the springs and why was this kit soooooooo late in coming.
