How much do you weigh ? I am positive the Raptor spring is the Polaris spring, have seen them side by side and look identical. I have the Polaris spring in my 13' F800 and it was an upgrade but still not like the dual spring kit from Hygear, I like the rough and the center shock still bottomed fairly easily.Finally got some miles on the sled this weekend in some really poor trail conditions. I’ll say this with conviction, for $60 this has been my favorite upgrade to the sled for the money. Rode in a lot of junk and I don’t remember bottoming out once. Rode so much smoother and handled the stutter bumps better. Thanks for the recommendation on this spring. It made a world of difference for me.
