I have a 07 150 with a 9.75" 3.55 ratio conventional rear. What all do i need to change over to a 4.10 ratio LS rear?

 

all you should need is a set of gears and a limited slip of some sort. wouldnt be a bad idea to do seals and stuff while your in there. dont forget if you regear the back, and you have a 4x4 truck, you gotta regear the front also, or else you cant have your front driveshaft connected

 

Are the gears that i will need different then the ones that are in there already. I am thinking that i need sometype of limited slip springs and clutchs. Not sure have not done rears before. I am going to have this done at a local garage but wanted to know a little about what im talking about when i go there.

Also my truck is 2 wheel drive so no front axle issues.

Thanks.
