Freeride doesnt come with the s module brace. But as mentioned, if you go with the either the summit or the freeride, install the s module braces from Grip n Rip for added protection.
I've owned both...2015 Freeride 146 and currently a 2015 Summit 154 (totaled the freeride and replaced it with the summit last season). The freeride was clutched, had grip n rip braces, and skis set to the narrowest setting. I wasnt a fan of the pro40 shock pkg, they acted lazy and soft. The wide front end and additional running board width in the rear increased drag during a sidehill. The freeride does accel on the trails and during a good jump session.
Because the summit runs cheaper than the freeride, i decided to set it up a bit different from stock. It has fox float 3's in place of the front shocks and front track shock, along with a kyb pro40 in the rear. Different handlebar and riser setup, clutched, and grip n rip braces. I am running the skis centered...roughly a 36" stance. I love the way the summit handles on the rough trail ride in, and especially how it acts in the trees and steep sidehills. The narrower front end is noticable. I use to disconnect the swaybar on the freeride when i was in the trees to get it to behave how i wanted, and now i find myself leaving the swaybar connected on the summit bc it does exactly what i want it to do.
If you install the braces and a better shock package on the summit, it will outperform the freeride in just about every situation. It will be just as durable, perform better in the trees, and jump/drop just as good.
One thing to note, the summits running boards are just as wide as the freerides where your feet spend majority of their time. The difference is that the freeride's boards dont taper back as soon as the summit's.
A trick that i learned on both sleds is that the rear skid mounting brackets need to be spaced out a bit in order to eliminate the track from rubbing against them. The t-motion allows the track to float side to side, regardless of how centered it is. By adding a few washers to each side, i was able to elminate this issue on both sleds. Hope this helps. Goodluck on the decision. Both are great sleds.
