Clutch upgrade?

In the process of replacing the stock clutch in my 99 f250, was just wondering what clutch you guys prefer to put in. Im thinking a southbend 450hp one. Truck is all stock, except 4in turbo back exhaust, might be getting a php chip in the near future. Pull a 35ft flatbed with stuff on it or a 4 horse trailer around at least once a week. Just looking for opinions or recommendations.

From my knowledge you are going to want a dual disc clutch if your going to be doing much for pulling. On South bends website they have a spot where it has some information on what clutch to choose. Hope that helps.

Pulling and towing are not the same thing. Dual disc clutches are $1700+ they are meant for sled pulling. And big power, he doesn't need that unless I'm missing something.

For towing the south bends are awesome, I have the 450/900 it's in my sig.

The 1939 series doesn't seem to be the real popular ones, you hear a lot more about the 1944 series that require their flywheel is more popular. There is lots of reviews on them.

I have about 500km on my southbend. The 1939 series has a fairly stiff clutch pedal, roughly the same as stock. The 1944's have a super soft pedal. My only complaint is this clutch takes a fair bit of finesse to drive slow

So the 1939 series is still 450hp but you can use the original flywheel? That sounds pretty good to me.

Yup I just had mine surfaced.

6 Speed HD Conversion Disk w/ceramic

The 1939CB is what I have and it's also rated for 450 yup. Mine seems good but backing to trailers or parking spots is a bit difficult but I've gotten the hang of it. Pedal stiffness is about the same.

The 1944 kits are apparently much nicer to back up and super soft pedal. Not worth 300$ to me

Yea the clutch in my 99 is easy since I learned on a 78 mechanical clutch. My left leg is slightly bigger than the right from that old truck

This was the page I was looking at. Does the pedal stiffness make parking harder or is it the way the clutch grabs?

If your gonna tow you need an organic clutch. Organic linings are smoother to operate, and you wont get any chattering when you got to ride the clutch when pulling out or reversing. I have a dual organic disk from valair, and will never buy another brand. South bend is good, but im not a big fan of the kevlar pilot bearing. If you can afford it go with the dual disk.
