I am looking at putting Fox Gas shocks on my brute force. The shocks bolt on to a snowmobile the same as the brute stock shocks do. This would keep us from buying new springs and they would most likely last the life of the bike without a rebuild kit, since the gas shocks are rebuildable. Has this been done before? Just wondering if anyone has any idea or if this could be done at all. If not I will be researching this and posting pics of the shocks and details on how to do it. It would save a ton of money and have great support for these bigger bikes.
