Looking at Progressive 440's 12" & 11.5" shocks. In their technical specs guide the following "Rate" in LBS/IN are listed:
Progressive has two 11.5" shocks
11.5" - Rate: 230/275
11.5" - Rate: 300/350
12" shock - Rate: 115/155
I know that a shock that is Rated at 100 LBS/IN means that for every 100 lbs. exerted on the spring the spring compresses 1". But what are the two numbers above mean?
And, if I'm looking to lower my V why does Progressive's install guide only list the 12" spring as the shortest spring they advise V-Rods to go?
