There are a couple of pics. The top mount center location is 11.4 mm from front edge and same distance from bottom of bend on the mount.
The new stop location on rails is 7.9 mm from top of rail and same from top inside edge of original hole.
It looks very much like a Holz skid 'cause the geometry is the same.
What this does is put the shock linkage into the stiffer part early and allows you to use much less pressure to get the correct ride hieght. The lower pressure allows you to use all the travel but the exponential spring rate of the air never bottoms (yet, lol).
Very nice transfer and as plush a ride as the valveing allows.
To set the ride hieght for your wieght, sit on the sled and measure from the floor to the rail at the rear arm mount. It has to be 3.5 inches (again the same as a Holz is set up. On mine the static hieght (unladen) is 19.5 in. and me sitting on sled is 16 in. I have found that in the field the pressure doesnt change much from the shop. I think because of oil temp., so just set it and forget it.
I run 85 psi in powder and 90 on the harder snow for my 250lbs with gear. If you dont set-up for this sag it will ride rough and not transfer well because the air spring wont let it use the full travel.
Front shocks at 55 psi and middle preload for the steering effort you want.
Hope you get the idea from the pics. Works very well for me.
