Just for knowledge out there.
The dss axles use stock inners parts.
I dragrace my V8 cougar, on the stock axles, I kept breaking the outer stub. Three times.
I switched to dss axles, they were good for three years.
A better torque converter and a bluprinted stocker (O/SA) engine, it broke the inner stub.
This was probally due to wheel spin, then the tires hooking.
But it still broke.
The axle is fixed with from the many spare axles I have.
But it damaged the mini spool as well.
After all this nonsense I just wrote, My opinion would be for a full time drag racer, go with a solid axle
with ladder bars or 4-link.
Street driven do what your wallet allows.
