I have an Eaton ho52 rear axle under my '69 c20. my question was would it stand up to the stress of drag racing? It has 4.56 gears in it. thanks.

would I need to lock the gears?

I'm new to the drag truck thing obviously I shouldn't used an 8 lug axle but its what i got so I'm gonna roll with what I got.
