How much power and towing can it support?
It’s commonly listed around ~650 HP / ~1,300 ft-lbs with a “30K Tow” capability when the overall setup (gearing, cooling, driver technique) is dialed in.
Is the pedal heavy?
No. The diaphragm-style pressure plate delivers lighter pedal effort than many performance clutches while maintaining strong holding power.
Does this fit NV4500 or NV5600 trucks?
No. This “5G” version is for the Getrag 360. Use SDD3250-5 for NV4500 and SDD3250-6 for NV5600 HO applications.

Not always, but older hydraulics can struggle with higher clamp loads. Many owners replace or upgrade hydraulics during installation for consistent release.
