Appreciate some advice on progressive rear spring for a Fatboy

[fatboyharris]

Hi,

I'm looking at replacing the standard rear springs on my 1990 Fatboy, I do not need to change the ride height and I'm usually carrying a passenger, so what are my options:-

I have looked at Progressive Springs series 413 and 422 and it's not quite clear as to the real differences and which suits my riding style/requirements better.

Are there are any other manufacturers, people would like to recommend, I'm not into splashing out for air suspension and are looking for the best value springs to improve the ride and handling of my bike.

Many thanks in advance
regards

The 422's are a replacement for the 413's,so you might be able to pick up some 413's cheap somewhere.
I have the 422's on my Heritage and am very pleased with them after getting the preload adjusted,as they are factory set at minimum preload.
