What makes you think the 8.8 isn't stronger than then 8.25.
And as far as weak tubes? I've got 3 people in my wheeling group that run them. We welded the tubes to the center section and have been beating on them for 6 years (we all did the swaps within months of eachother)
I broke mine for the first time last summer. Been running 38s the whole time and hit a rocky ledge hill full throttle and bounced. Only problem we've ever had out of them
