Thanks Ross. Is 12" the eye to eye measurement?
I'm curious what your front frame to ground measurement will be and your tire height.
Also, which HDK are you using?
12" is the center eye to center eye, the square tube on the left is the 12" and the one on the right is the 13" for the rear.
Mine are non-adjustable, if you used a turnbuckle or all thread in the center you could dial it in, I just made different sets for front and rear.
If I remember correctly my frame to ground measurement is 13", that measurement was taken about half way between the Factory K frame bolts. Tire height is 26.4".
HDK is the Slammer version, I think.....Denny may have to confirm that.
