The Polaris supplied ones have a single rate in them... and the stiffer assault valving.
For he same price the Tri City Performance Versions of the WE piggyback compression adjustable shocks have a dual rate spring and were dialed in my TCP for the Pros. They have them available to fit the 10mm mounting bolts of the pros.
So what's going on here? Not long ago the word was the shocks from 08-10 were a different size/length than the shocks for the new 11 PRO. What changed from then until now??
I just got off the phone with Max at Tri City Perf.... Tri City Performance DOES have the Piggyback needle shocks for Pro RMK in the correct Eye to Eye length, 17", and bushing-eye diameter... valved for the Pros and for the 2011 Std 800 RMK's With dual rate springs.
That's the answer to my original question I would say. I'll ride mine and if I think I need something better those will be what I'll look at. Thanks MH.
