There has never been a question of me upgrading to 26-spline.
I was just debating on changing out the half shafts. Typically, when do half shafts break? Is it during a high RPM lauch or slamming through the gears...say on street tires?
typically, when you wheel hop. I have seen some failures with just straight on hooking like a SOB with a lot of power, but rare.
