So I think I had gotten bad valves from Amazon. They were cracked and dried out on the 2 JD carts I leave outside. Anywho I had installed these Amazon valves on the 2 JD carts and the 800s beadlocks. So once I realized the valves were cracking I purchased these Colby valves because I especially didn't want to break down the beadlocks. Well I installed the first one on the 800 and seems to be a solid valve and simple install. Hardest part was making sure the entire old rubber valve came out. Cause I would have broken down the wheel if the back of that valve fell inside the tire, lol.
