I just spoke with Andy at Gas Shock Repair... He can shorten the 17.5" floats safely by 1".
His charge is $25 each to shorten the body and shaft. Plus $24 each for the service (clean/new oil/nitrogen/reassembly). Add $5 if you want him to revalve to your spec.
The cost is the same for coil-spring shocks like the Factory Walkers or other.
Very reasonable in my opinion.
Also... After chatting with some other Polaris owners... and Andy...if you have your 17.5" shock Shortened to run on the arms requiring shorter shocks...Have them shortened to 16-5/8" and then run a small slug -spacer inside of the shock if you want to go less than that.
This will allow you to always return to the stock 16-5/8 length if you want to sell them or use stock arms again.
IMO... Not the best idea to take up the full 7/8"-1.25" with just a slug-spacer as this will limit your travel and give a harsher ride. Possible, yes... but you are giving up on about 20% of your travel.
NOTE: When referring to shock length... The stock 2011/12 PRO-RMK's come from the factory with 17.5" shocks as do the 2011-2014 Std. RMK's and the 2015 regular season std RMK (non-snowcheck)... All of these are 17.5".
Stock 2013/14/15 PRO-RMK's come from the factory with 16-5/8" shocks. Also the 2015 Standard RMK's that were ordered during snowcheck, with the Walker Evans shocks with the bonded lower A-Arms... these all feature the 16-5/8" shock from the factory.
