South Bend Clutch13125-OK Clutch Kit

Clutch is a great replacement/upgrade on a mildly upgraded Cummins 12v with nv4500. Pulls hard. My truck has around 350 hp and easily double that in torque. Tow regularly in excess of 10,000lbs clutch holds great. I installed the heavy duty hydraulics from south bend with it . Pressure plate is slightly heavier feel than stock about 35 pounds of force on the clutch pedal to depress . It does hook up harder than a stock clutch so don’t expect to ride your clutch because things can get violent . Not a problem though if your a seasoned driver with good experience driving standard transmissions. . When backing a trailer though I’d highly recommend kicking the truck in 4lo if you don’t have 4:10 gears . Slightly larger flywheel but it will fit a 100percent stock truck with no modifications and the factory input shaft in the transmission

Holds it down no more slipping. The max torque and hp rating for this clutch is a very conservative estimate.

After buying this here I had weird messages when I went to Southbends website-I guess they didn't like the good deal I got from Amazon. Very Good product and works excellent

Quality like I have never seen before out of any clutch company. Interested to see how it tows 27000 day to day.

Purchased this clutch March of 2020, installed May of 2020. Failed yesterday. My truck is well within HP / torque spec of this clutch. Appears the throwout bearing failed, but will know entirely the damage when ripped out. Of course I am out of manufacturer warranty, and South Bend wants absolutely nothing to do with me.

Fits and works great in my 91 12v dodge.
