to get a smoother ride with a decent lift you can relocate your rear 400 shocks on the front. You will have to make some upper bushing to install in the top mounts of the rear shocks, its real simple. you will see what I'm talking about once you remove them. On the rear you can buy a used set of rear 450 shocks cheap off ebay and install them on the rear. Here is a picture of the wifes 400 with 450 supension all the way around. So dont compair the front, it has more than just shocks. I posted the picture so you could look at the rear. It is also sporting 27" tires.
