Peterbilt introduces new frame rails

Peterbilt Motors
Peterbilt has announced that new 11-5/8-inch frame rails are now available for the Peterbilt Model 379. The frames provide enhanced frame strength for severe duty applications.

The new frame rail option will accommodate all engines, transmissions, hood lengths and sleeper sizes available for the Model 379, and is also a weight-saving option when compared to other severe duty frame rail options, the company says.

For instance, the company said, a customer can save about 120 pounds versus 10-5/8-inch frame rails with suspension inserts on a Model 379 spec’d with a 220-inch wheelbase and 53-inch overhang. The 11-5/8-inch frame rails were previously available only for the Peterbilt Model 378 and Model 357.

Additionally, the 11-5/8-inch frame rails are a good choice for vehicles spec’d with multiple pusher axle configurations, Peterbilt added.
