FAQ
Is this kit pre-bled and ready to install?Yes—NMU70HYD-01 arrives pre-bled for quick installation and consistent pedal feel.
Will these hydraulics work with a heavy duty clutch?Yes. They’re designed to handle higher clamp loads common with performance single-disc and dual-disc setups on NV4500 trucks.
How do I confirm I have an NV4500?Check the transmission ID tag or the 5-speed shift pattern. If you have a G56 (’05+) or NV5600 (’00.5–’05), use a different hydraulic kit (see alternatives above).
Do I need other parts when replacing hydraulics?We recommend inspecting the release fork, pivot, and spring and replacing worn components. See the recommended parts above for direct-fit options.
