When lengthening my rear shocks do I need to lengthen the fork springs too?
I want to get the Progressive 12.5" 412 shocks for my '07 883L which has 11.5" stock shocks and a stock lowered front end. Would I need to lengthen the front springs by an inch as well? Or maybe a spacer to add the inch? What's the retail for the Progressive fork springs? I'll probably have to save up if I have to do both at once. Thanks.

What I found with my bike is that the forks sag far too much, leaving only around an inch of travel. So your suggestion of putting in an inch of spacers is a very good idea. It should lift the bike to where the forks should be from the factory.
There is supposed to be around 4" of fork travel, from fully extended. Some of that gets lost with the rebound springs, but we should have at least 2" travel left when sitting on the bike, ready to ride.
I actually had single-rate springs and Emulators fitted to my bike, but other than lifting it as I described I don't reckon it rides much better than before. So fitting spacers is a far cheaper and quicker way ahead.

Yes, the Progressive fork springs are well worth the money IMO. The stock springs are weak and sag eventually. No need to disassemble the forks, just raise the bike on a jack to unload the front-end and remove the cap nuts on top of the forks. BUT, be careful, they're under spring tension.
I recommend buying a fork nut socket to prevent damage to the cap nuts and it makes the job easier.
