If you have an older Yeti kit and have not done the shock shaft updates, you should! I had heard about the update kits but thought that I didn't need to do it as I don't ride too hard and don't drop cliffs, well yesterday on a beautiful blue sky day with about a foot of fresh snow I broke the front shock lower shaft on the trail on the way into the riding area. So had to limp back to the truck and go home early. Old shafts aluminum new shafts titanium, hope they are stronger.
