FAQ
How much power and torque will this hold?It’s built for street/tow trucks up to about 550 HP with strong torque capacity thanks to the dual-disc organic facings and 3800# pressure plate.
Is a flywheel included?Yes. A new nodular iron G56 dual-disc flywheel is included with hardware for a direct-fit install.
Do I need separate hydraulics?No—this kit includes a pre-bled hydraulic kit. Some customers still keep a spare set on hand for long trips; see the recommended parts above.
Will it chatter or be hard to drive?Organic facings prioritize smooth engagement and street manners while offering a big jump in holding capacity over single-disc kits. Proper break-in helps minimize noise.
How do I confirm I have a G56?Check the transmission ID tag/case. If you have an NV5600 (early 2005), select an NV5600-specific clutch instead.
