Sounds like you might need an alignment. Have you checked your tires for equal pressure in all of them?

LMAO at people thinking alignment would be an issue if it pulls during acceleration!

do you have adjustable lca's?. are you sure its not the road? grooves or low "channels" in the road will cause a vehicle ( more commonly with wide tires) to pull one way or the other.

I noticed this when I put in my 9". I'd guess it's because I need to properly center/align the suspension. LS1>girlfriend: have you personally driven a car with a 9" that hasn't been properly aligned?

Which differential are you running? Some types of posi's will do this more than others (lockers for instance are known for this issue) as they try to equalize the torque. And how it was setup will make a difference too. I had a 'clutch-n-spring' type in my 9" that was setup TIGHT & it never pulled, it went absolutely straight running mid 10s!

If you have a Detroit Locker it's just not fully locked when you accelerate.

Why would that matter?
