General Motors is making a box delete option available to fleet and retail customers on its 1500 two-wheel drive and four-wheel drive Regular Cab Chevrolet Silverado and GMC Sierra. With this offering, the automaker said it is completing its pickup portfolio of box delete offerings.

“We are in the business of meeting our customers’ needs by providing a range of products and solutions that fit their businesses,” said Ed Peper, U.S. vice president, General Motors Fleet. “Light-duty box delete is a direct response to our customers who have been clamoring for it.”

The new light-duty configuration eliminates the box, rear bumper and spare tire assembly, and includes high-rate rear springs and a front stabilizer bar from the Max Trailering Package for better performance when operating near the truck’s maximum gross vehicle weight rating, according to the automaker.

The box delete option will provide a credit of $575 from suggested retail pricing. The spare tire assembly can be added back on for $335.

“The Silverado and Sierra light-duty box delete models have been designed to take on the work our customers do every day,” said Dan Tigges, commercial product manager, General Motors Fleet. “For customers with lower payload requirements, this new option will reduce upfront costs and provide fuel-economy advantages compared to heavy-duty box delete alternatives.”

The new light duty models will join the Chevrolet Colorado and GMC Canyon mid-size extended cab trucks with a box delete option, as well as the Silverado HD and GMC Sierra HD box deletes and chassis cabs.

The Silverado 1500 2WD Regular Cab box delete starts at $29,155. A box delete 2500HD 2WD Regular Cab box delete starts at $33,475, providing more than $4,000 in upfront savings for the light-duty box delete buyer. Significant annual fuel savings are also possible for the light-duty box delete, according to the automaker.
