Just curious as to why you think a limited slip rear end is bigger the an open differential? They both use the same carrier

I think gui88ford is talking about the center rear axle diff housing. The limited slip clutch packs on each side of the diff make it a wider unit.

The "pumpkin" is the same size, regardless of if it's an open differential or limited slip. The 9.75" sterling differential which is what the 5.4L uses looks very similar in size to the 10.25" sterling rear that gets used in the F250 rear end. The Ford 8.8" however gets used only with the 4.2L or the 4.6L

My 07 Super Crew, Lariat 4X4 has a 9.75, 3.73 but it WAS an open rear end. It is now a Truetrac ls. This truck really rides nice and I just finished putting on a K&N series 63. That joker is LOUD when you step on it. It does seem peppier but that may be a $248.00 placebo from autoanything. The jury is still out.
I also just back from towing a trailer full of atv's to Okeechobee, Fl. (pre series 63) Towing through Miami, 12 mpg on the way up and 14.5 on the way back. Less traffic and heavy wind on my back on the way home. Going again in a couple of weeks, see if the 63 makes any difference.
