Clutch information needed
OK, I have a 2001 4x4 Crew Cab 7.3 Powerstroke with 104k miles, 4" exhaust, superchip tuner, and injector pressure modifications. I bought the truck at 68k miles. I assume it still has the original clutch in it. I just did all of the upgrades & modifications after I passed 100k miles. Now, in 3rd, 4th & 5th gears, if I get in it, my clutch "spins". I tow with this and it is a daily driver, so I don't want to lose that aspect of driveability. Any suggestions on what kind of clutch I should go with? I want to upgrade to something stronger than the factory clutch. Also, I have been getting a LOT of conflicting answers, does the 2001 have a dual mass flywheel or is it a solid flywheel. Thanks in advance for any advice/wisdom!

Your truck has a solid flywheel currently. If you decide to upgrade the clutch to a Luk or a HD Luk you will still need to replace the flywheel. Give me a call tommorrow and I can explain some of your options with pros and cons.

The standard LUK upgrade is a good (relatively) low cost unit that will be perfect for you.
All 99-03 7.3's have a solid flywheel.....except for the one's that have a flex plate

I was told by a LUK dealer that the standard LUK upgrade wasn't worth doing because it would handle basically the same power as a stocker, and to either go with a stocker, or a big, bad-boy clutch.

Evidently that particular dealer hasn't ever owned one of his own clutches. I know for a fact that it will hold at least 1.5 times the factory rated RWHP for at least 57,000 miles.........so far.

Call Larry here http://www.discountpowerparts.com/. Ask him about a South Bend Clutch. I used the CON OFE single disc untill I started sled pulling. Now I use their twin disc.

I had heard the south bend clutches were pretty harsh in a daily driver and not good for normal everyday towing/farm use. I appreciate all of this information. Anybody used a Spec? How cheap is the "relatively" cheap Luk clutch?

It's pretty much the only clutch you can get that can handle low 300 horsepower engines without costing $1000. Pedal effort with the base Luk is substantially less than stock. It is a very good entry level performance clutch in my opinion.
