I have an 06 ultra classsic, I weigh 300#, old lady weighs 180#, and I am wondering if the 440 shocks are the way to go, and if so, which height do I need?

 

13 inch for the best ride.I would not go less than 12.5inch.I have had both sizes & like the 13s,but I ride the USA(30,000miles+ yearly) Also since you weigh #300,request the ones with the heavy duty springs.There is no difference in price. www.wallyscycleworld.com has them for under $400 shipped.Regards,Tom
