what i have done, 98 srx: replace radious rods and tie rods with mountain max ones. this will narrow your stance and raise the front end up about 2'. Hauck adjustable shock mounts added, good for about another 1" rise, all using the stock shocks. this helps a bunch to keep the nose out of the snow. have now added viper trailing arms and spindles as the viper arms are about 1 1/2" taller than srx. still working on the steering geometry, turns and steers good but the viper steering arms wont paralell the trailing arms like they are stock. tried to put viper shocks on the old girl, but they were too long for my sled with additional parts i installed, and were completely compressed and bound the suspension. may have worked without the skidplate, but i gave up.
