  • Hello will this help with stiff clutch pedal. Everything is new. Brought cheap hyd system from.ebay I've been told that's probably why pedal is stiff. 04. Cummins 3500 nv5600.

    Joey stidham | 12/24/2025

    No, designed to work valair clutch kits.

  • How can I tell if one of these was put on when a dual disk kit was installed

    Nathan Conard | 4/12/2024

    You would have the plastic reservoir on the firewall

  • I'm putting in a clutch and hd hydraulic kit a custome purchased from you. HD Hydraulic p/n NMU70HYD-03, but the new resevoir for the master isn't part of the master cylinder anymore it has it's own plastic bracket on it. Where am I supposed to mount the master cylinder? The master that came off the truck had an integrated resevoir, so there wasn't a resevoir to mount anywhere and I don't see any other bracketry to mount this new part to. There is nothing in the instructions about mount location

    Usually to the firewall between brake fluid reservoir and the old clutch master cylinder.

  • Will this work with a South Bend dual clutch set up?

    Kevin | 1/14/2022

    Yes, we do sell South Bend’s hydraulics also.

  • Mine is coming up that it fits a nv4500 and nv5600 and g56. But when i but in my year truck (2003) it says that its showing me one for a nv5600 and doesnt give me the option to choose a nv4500, are they the same for the nv5600 and the nv4500. I have a nv4500.

    Isaac Mohr | 9/15/2021

    Fits all model years 2003-2017. Nv450, NV5600 and G56 transmissions.

  • Will this be okay working with the stock clutch?

    Spencer Rod | 3/2/2020

    Yes it will work fine with a stock clutch.

  • I bought one of these form you guys is there supposed to be a bushing where it connects to the peddle?

    Ross black | 11/7/2019

    No bushing is required.
