How long is the break in period on MP 4.10.

 

Well as soon as you start it up and start too drive it worked for me

 

I thought I heard 500 miles before you really get on it.

 

There really is'nt anything to break in.But you can be safe and wait 500 miles.

 

whoops I think i waited about 3 miles...

 

I did'nt even wait that long

 

There is no break in period. They are either going to be fine, or there is going to be a problem and youll notice it.
Take a quick drive and listen for problems during accelleration and slowing down in gear. If all is well, get used to your new fun.

I had mine done, took it around the block and listened for anything, and all was well so I turned onto the street and ripped that badboy to about 100. man it felt like a new car,

 

I'm getting them installed tomorrow, and it's raining here so I'll have to wait a day or so regardless, cause from what I've heard wet roads and 4.10s at WOT don't mix.

 

how much are u payin for them to be done? And is it a professional shop or a friend?

 

About 30 feet, backed out of the garage and put on the trailer to take to the drag strip.....8000miles ago multiple slick launches, no problems.

A friend of my uncles is putting them in for 125$, and it's a professional shop.
