I have a mach one 8.8 rear end in my car and was wondering if anyone else has a 9 inch in theres and how much stronger it is than the 8.8

a kid i know has one hes been workin on a 2 year build still havent seen the road but should make around 700...but its not needed at all just more of a pain the 8.8 with stronger axles and diff will work for what ever power your stock motor could throw at it..

Stick with the 8.8", they're pretty strong! ... and build as necessary!!!

i just feel like im going to break it cause i already have and only got on it a couple times

i have an eaton hd differental 31 spline axles 3.73 gears welded torque boxes and axles tubes 2 step and no lift shiftboxes being launches on 24x16 slicks and it didnt budge and it wont youll break your tranny motor mounts clutch bent rims universals all that stuff before you snap this rearend....dont switch it will be a wasted money put if you just build your rearend it will be stronger then any power you can throw at it with a total total rebuild

How hard is it to put the 31 spline axles in and the new traction lock for it

built 8.8 is far cheaper and just as strong. You can probably peice together a seriously solid 8.8 for 1000 bucks and not have to worry about much. A stock 8.8 probably wont last long if your making decent power.

i can get a detroit trutrac diff for and 8.8 with 31 spline axles for 500 bucks is that a good deal

ya thats prolly alittle deal but idk detriot to tell you for sure...and you must have a shop shim in the rear differential if not it will make some lovely sounds and eventually destroy itself...
