8 1/4 rear end , looking for advise on a surgrip assembly

We have the weaker of the two in our duster and have prob 50-60 mid 11 sec passes on it and prob hundreds(dunno exact, lets just say frequently abused) 12 sec passes on a 26x11.50 hoosier quick time pro dot and it still works without any issues or funny noises,but I think this rear might be the exception to the rule and not the norm.



Good luck,
Jr.

I know the chrome stick on flames look funny but they're the best bait in the world lol.
