Below's a part number for a limited slip differential and 41 spline.HC3Z-4026-H

Very good, we have the dealer looking into it. Thank you.

I know it's been a year, but was curious if any had seen or know if plans for a locker that will fit a 450 or 550? Ordering truck and if locker is available aftermarket I will go that route

I never did get this resolved. I went around and around with dealership on the limited slip and gave up at that time.

I did install a winch for the time being. I also would like to know if a aftermarket locker is now available.

Thanks.

You can get a factory limited slip rear end and aftermarket selectable locker for a dana 60 (front axle). Check the ford build and price website, its an option.

I would contact a gear or 4x4 shop that specializes in this.

I wouldn't waste your money on a limited slip. The performance is not worth the price.

I realize this is an older thread, but here is some hopeful news:

This is from arbusa on instagram this morning regarding a locker for the M300:

"Yes we are in development to make an M300 - it would be for the Ford F450 - 41 spline. No eta on when this will be completed."

We’ll install it once it hits the market.
