Customers purchasing new Peterbilt vehicles equipped with engines certified for the Oct. 1, 2002, EPA emissions standards can now receive two complimentary Alcoa front aluminum disc wheels.

The new program, available for a limited time, is valued at up to $936.

Peterbilt is also offering discounts on the lightweight Flex Air suspension, and extended warranty coverage for select Cummins engines and Eaton transmissions. This is being done to help ease customer concerns about the impact new engines may have on operations, the company said.
