I couldn't agree more. We just got back from our first camping trip after I installed my Sumosprings on our 2001 Tundra. With the 5er attached, the bed dropped maybe 1-1.5 inch whereas before it would drop 4-5 inches. The drive was much better as well. A lot of the bouncing was eliminated. I looked a lot at the firestone airbags and almost pulled the trigger on a set until i heard about how,over time, many develop leaks. I wanted something low maintenance. Just replace the stock bump stop with these and you're good to go. It took me about 45 minutes. Nice product for sure!!!
