Full-time four-wheel drive is optional on the Silverado HD. Full-time four-wheel drive gives added traction for safety in all conditions, not just off-road, like the only system available on the Ram HD.
The Silverado HD’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. A lane departure warning system costs extra on the Ram HD.
Both the Silverado HD and the Ram HD have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available blind spot warning systems, around view monitors and rear cross-path warning.
