What is that? How are they different to a normal flywheel?

not avaliable for 6cyl, V8 you would have to check with someone like yellaterra, no real gains to be had out of one really, better off with a good quality lightened fly wheel, achives the same goal

For those wondering....myself included I just googled it and found this. Seems like they're more suited to $WD and light trucks to me

Some notes on application pros and cons:

The dual mass systems are designed to transmit less engine vibration to the driveline, and give a better more car like driving experience. They also reduce some of the jarring and stress on the transmission and remainder of the drivetrain. They work fine as long as the engine remains unmodified and the vehicle is not used/abused beyond manufacturers recommendations.

As soon as you start to increase the engine power over stock, or load the vehicle beyond design parameters, you run into problems. Dual mass flywheels are tuned systems and must be matched to the engine torque curve, engine resonant characteristics, vehicle load curves (including axle ratio/tire size calculations). They work by having a set of springs inserted between two rotating masses (thus dual mass). The springs are sized to soak up some of the resonant vibration from the diesel engine under load conditions. A dual mass fly wheel generally also contains an over torque friction release, so if it gets suddenly overloaded, rather than damage the springs, it slips. This works fine as a safety valve, but if it does it much it burns up. In short, overloaded they burn up and the springs get destroyed and they are worse than if it were a single mass FW.

The single mass part WILL tend to transmit more engine pulse (vibration) tot he drivetrain, and will seem a bit rougher. But it is straight forward to design a single mass flywheel and clutch package for pretty much any engine torque curve and vehicle loading combo you can come up with. Drives more like a TRUCK, but has much better reliability at extreme use levels.

Depending on what you have done to your engine and how you use and load your truck, we can supply a single mass flywheel and clutch system properly sized for your truck. Ballpark $600 for a mildly massaged engine, more for extreme applications. 8-)
