I don't know how much power it takes to bend Dana tubes? But mine hasn't bent them in 525+ passes at somewhere north of 900hp. 1.25-1.30 60ft@3350lbs (or 3500lbs+ with ballast). The first Motive street gear went 425 passes before it bent a tooth. The 2nd no name street gear only went 100 passes before it broke pinion teeth. This time it got a US gear Pro Gear. I also added the LPW cover like shown above. Braces were not added at this time. We'll go do some real word testing and see what happens,
