Thanks very much. I had the spacers made from your droop thread but my rear adjusters were already on max so i think i i need longer springs.

A higher rate 728# Swift spring yields Flat Ride. I bought a 6" and with the adjuster all the way down I have a 13 1/4" rear ride height. I'd suggest the 5" for anyone considering this combo.

Yeah I have the swift 672 rear in 5", I'm about half way on the adjuster to get to proper height.

I'm happy with a rear ride height of 13 1/4". The problem is I've lost adjustability. You made the better choice of spring height.
