Rear Ends...

[cdg1984]

Okay so I know most of this is personal preference/opinion but does anyone think that the 7.5 rear end can hold a fair amount of power with the right gears or is it better to just up grade the whole unit? I am thinking about doing a 9 inch with 3.90's but if people feel that the 7.5 can hold a fair amount of power then i might just do a gear swap.

You can build a 7.5 to handle some decent power, but for the money you would spend doing that, your close to having enough for an 8.5 or 9
