The MP 2225 Transfercase is the only AWD upgrade Tcase for the Hummer H1 and HMMWV. These came on the latest ECV HMMWV's that are 16,000lbs.
MM Specific Improvements:
- We open every brand new tcase to add the High/Low switch in the front case half.
- Also we install our MM Billet Tail Housing that will use the stock VSS (vehicle speed sensor)
- We make it 100% plug and play, use the same driveshafts and sensors plug right into the factory H1 harness.
List of Improvements:
- Chain is 20% wider and therefore much stronger
- Significantly improved cooling loop that now runs of engine coolant.
- The case halves have a lot more bolts for better sealing and ultimate strength.
