General Motors has rolled out a round of sales incentives for its redesigned lineup of full-size pickups, saying it needs to keep up with deals being offered by competitors.

GM is offering zero percent financing deals on 36-month loans on certain versions of the 2007 Chevrolet Silverado and GMC Sierra.

The company also is offering reduced-rate financing on 60-month loans for the trucks.

Depending on the model, customers can choose between $1,250 and $1,500 cash back in lieu of the financing. The deals run through July 9.
