Driveline weight difference?

Recommended Posts

I have a friend who wants to build a truck but weight is an issue for his company he works for. Our question is what's the weight difference between Mack rears compared to Eatons? It's obvious that the Mack verses eatin trans is a huge difference but we are still uncertain exact weights. 

We are thinking of moving the back axle to the front and just making the rear a tag to save in weight. Any thoughts would be appreciated. Thanks Joey

Isn't a Mack tranny lighter than an Eaton? The dealer will have all the specs on everything you can order. As you add options it'll show you how much weight each option adds.

Due to the triple counter shafts its a lot heavier!! all depends what it is used for Box- flat -dump -tank Eaton wont hold up to older Mack motors due the hi- torque Mack trans 1800-lbs verse Eaton 1250-1450 toque range and the right injection pump.
