I need a stronger 10 bolt rear and don't wanna spend 2500 on a 12 bolt and lose more power through it. what can be done to a stock 10 bolt to make it stronger??

T/A differential cover with bearing girdle. Actually pre-loads the bearing caps to prevent distortion. This will help, but this is still a very weak rear-end. I ran with Nitto Drag Radials for about a year, with some serious launches, but I felt I dodged a bullet. Just know you are living on buried time and you will be fine.

If you have an auto, you should be fine all the way deep into 10s.

There's no guarantee as to how long a 10 bolt will last, it may break on a 13 pass or it may break on a 10 sec pass. Simply put, it's too small to handle stock power let alone modded.

Get a 12 bolt and suck up the power loss. You'll more than make up for the power loss in the fact you can launch with confidence with full power.

^^^What he said. You won't lose that much power anyways. Not enough to notice. I went to a 9" with just bolt ons and the car doesn't feel any different really, but now I can leave off the line at 5500rpms and make up for what little I did lose.

JEG'S or T/A Aluminum differential cover, strange axles and straight cut gears (they whine but are stronger).

Agreed. I see a ton of autos going fast with no problems. Just preload on launch, and it won't be so hard on your rear.
