    The MP 2225 Transfer Case is the only AWD upgrade T-case for the Hummer H1 and HMMWV.  These came on the latest ECV HMMWV's that are 16,000lb GVWR.  

    Standard Features:

    - Chain is 20% wider and therefore much stronger

    - Significantly improved cooling loop -- uses engine coolant

    - Case halves have a lot more bolts for better sealing and ultimate strength

    MM Specific Improvements:

    - We open every brand new tcase to add the High/Low switch in the front case half.

    - We install our MM Billet Tail Housing that will use the stock VSS (vehicle speed sensor)

    - We make it 100% plug and play:  uses the same driveshafts and sensors, plugs right into the factory H1 harness.

    HMMWV version available, contact us for details.
