Looks like your axle is plenty strong already. When my rear axle suffered wheelhop off the gate ( bad track prep plus overpowering the stock leaf springs ) the ring gear let go but the pinnion was ok. Yes the TH350 first gear broke too. Was a foot brake launch.rustbucket79 wrote: ↑Sat Feb 10, 2018 1:27 pm
My 10 bolt (8.5) has a Strange spool, 33 spline axles, c clip eliminators, TA cover and bearing cap studs. Is that the setup you run? What brand of gears and ratio? N/A or power adder? Tranbrake? Stage RPM? 60’ times?
I would love to throw a set of 4.56’s in the car but I am concerned about breaking a gearset and messing up a $4000 transmission 🤬.
I do believe a 456 pinnion will take your engine's power, just avoid wheelhop.
Have you a T brake?
