FAQ
How much power will the G56-OFEK hold?It’s commonly rated around ~475 HP / ~1,000 ft-lbs depending on vehicle weight, gearing, tire size, and usage. If you need more, consider a G56 dual-disc option.
Does this replace the factory dual-mass flywheel?
Yes. The kit includes a solid (single-mass) flywheel for improved durability and heat control under load.
Is pedal feel still streetable for daily driving and towing?
Yes. The OFE lining is designed for smooth engagement and controllability, making it suitable for daily use and towing when properly broken in.
Do I need upgraded hydraulics?
Not strictly required, but South Bend HYDX.750 hydraulics are a smart add when increasing clamp load or if your stock hydraulics are aging.
Will this fit my NV4500 or NV5600?
No. This kit is specifically for the G56. See our G56 clutch category for more options, or shop NV4500/NV5600 sections for those transmissions.
