I will soon be in the market for a new clutch and wanted to get some of your thoughts. I have an 04 5.9L with a 5 speed trans,Smarty JR,K&N intake. I want to use this truck for mainly pulling my camper which is approx 5,000 lbs and occasionally hauling gravel which trailer and gravel loaded weight would be approx between 12,500 to 15,000 lb. I was looking into South Bend clutches, but I'm not sure if I should go with a higher HP 13 inch single disc or maybe the 3250 double disc. One question I do have is the single disc clutch ratings for Hp of the motor or at the rear wheels? I appreciate any info from all of you.

 

Call Peter at SBC.

If it were me, I would 3250DD it.

 

The HP ratings are rear wheel.

I would NOT get a DD, they're noisy, slow shifting, grabby, hard to back up a trailer. Lotsa people on these forums go bigger than they need.

The OFE has been great, rated for 450 but will take much more, one guy ran 580 through his before going to a DD and the OFE is now in another truck.

Pedal pressure is a little firmer, just the slightes bit more grabby than stock but generally feels pretty much like the stock one.
