I have an 07 Dually 6 Speed. I pull about 16K or so wiith it. The clutch let go after 15k i guess this is the weak spot? Put a center force in and have had no more problems. The factory only rates the truck for 13.5 (i think). How much are you guys pulling with your manual trucks?

 

My trailer is just over 12k.

 

Between my fiver and gooseneck I pull between 12k and 15k and I have 183,000 on the stock clutch

 

But your lucky and didn't get stuck with the dual mass and g56.

Anyway I pull between 17,000 and 19,000 pounds. I'd never buy another 6 speed as long as we get the g56 and dual mass.

 

15k to 26k but thats with a valair clutch.. My factory went out at 60k

 

I don't haul a lot, but I've put several thousand miles on with an 18-20k trailer on the stock clutch. Haven't had a problem so far.

Only problems I've had are when I turn the Adrenaline up and start playing. Then the clutch slips. Long as I keep it down it's not a problem.

 

It's a weak spot yes, but 15k miles is way low. Get off that clutch before you get into the throttle!

 

17K with Smarty Jr stacked with Edge Juice with attitude, HE351 turbo. So far the South Bend Clutch is standing up to all the abuse, my only complaint with it is that the clutch can be a bit grabby when first trying to start off from a stop.

 

I tow 18k all the time. Have 80k on truck no problems

you need to reread his is an 07 5.9 and severtal of us have the same drivetrain that responded. Mine failed on a stock truck

 

Sorry I have never seen a 2007 3500 dually here with a 5.9 or a dual mas flywhel coupled to it. All the trucks available to us were 6.7 dual mass units.

 

dual mass started in mid 05 with the g56 tranny and i had an 07 with 5.9. that was available starting oct of 06

 

What he said!!!!! Pull the slack out before you put your big foot to the floor and then more or less roll into it and not just stomp it.
I’ve pulled 15-18K on a regular basis for over 220K with no problems on the old 02, with the 09 over 25K so far pulling about the same.

 

I run 20-26K GCVW on average while on the road and 10K in town most times.

Mine bit it at 20K miles, but I think the Smarty and injectors had a little something to do with that?
