Depends...do you feel lucky? If you keep modding then I would say yes. If not then you may be ok. I have seen them break on stock cars.

yes you do.. i've gotten a trailer ride home 3 times in 5 weeks from the track and i'm not heavily modded at all! If you had an automatic i'd say no but apparently the shock loads with sticky tires are much more than it can handle. i'm not running stock gears(richmond) or a stock diff(auburn pro). Or you can keep hard street tires on it you'll be fine let lack of traction save your parts.

from the way it soudns if you break it in correctly youll be fine...Strange, Moser, SLP (engineered by Moser)

i'm unsure if 3.73's or 4.10/11's would make a difference in noise but if i hade to guess....id say 3.73's

im still learning more...my toss up is the gears...and if posi or spool....if i go spool uill prolly go Strange and if i go Posi SLP or Moser
