South Bend Clutch has developed a new 2nd generation Heavy Duty Clutch for our 2001 6-sp. I have reported to you on their 1st generation clutch which is capable of handlying 400+HP and 900+FLB of torque at the rear wheels, which I have Dynoed and is installed on my truck. Their 2nd generation clutch kit has a Luk original equipment pressure plate that has been altered to increase the pressure without increasing the clutch effort. This also changes the stroke of the clutch petal causing the clutch to engage smoother. The drive disk used in the kit is also Luk orginal equipment. They have changed the clutch facings from organic to a much higher torque carbon based metal lining to accommodate higher horsepower trucks. Another advantage to these particular metal linings are that the clutch system does not loose the cushioning effect that make a clutch feel smooth when it engages. For those of you considering upgrading your clutch because of "bombing" I would highly recommend you contacting "Peter" at South Bend Clutch 800-988-4345 for more information. I plan on installing in the near future the 2nd generation clutch and let you know how it truly performs. If it's better than the !st, it will be a winner!!! By the way pricing will be much cheaper than the Mcleoad, Sachs, or other clutches presently on the market for high performance trucks.
