FAQ

Targeted for about 650 HP / 1,200 ft-lbs on street/tow builds with proper tuning and tires. For smoother engagement at lower power, see the organic dual disc alternative above.

Yes—this street dual disc ships with a new NV5600 dual-disc flywheel plus bearings, hardware, and an alignment tool for a complete install.

The ceramic facings and higher clamp pressure add bite and heat capacity versus organic. Expect firmer engagement; complete the full break-in to minimize chatter.

For 2003–2005 trucks use NMU70HYD-03. (1998–2002 trucks typically use NMU70HYD-02.)

Check the transmission tag/case. If you’ve got a G56, use the G56 dual disc instead.
