When shopping for a full-size pickup, the 2017 GMC Sierra offers a compelling blend of capability and comfort, but selecting the right configuration requires understanding the specific bed dimensions. The bed size of this model year directly impacts its utility, determining how much cargo you can haul and how easily you can access that space. Whether you are a contractor hauling equipment or a weekend warrior towing a boat, matching the bed length to your specific needs is the first critical step.
Available Bed Lengths and Configurations
The 2017 model year provided buyers with three primary bed length options, allowing for a high degree of customization. These configurations were designed to serve different driving habits, ranging from urban commuting to long-haul towing. Understanding the specific names and dimensions of these beds is essential for comparing trim levels and packages accurately.
Short Box: 5′ 1″ Bed
The shortest option available for the 2017 Sierra was the 5-foot, 1-inch box, often referred to as the "Short Box." This configuration was ideal for drivers who prioritized maneuverability in tight urban environments or job sites that required frequent turning. Despite its compact size, it still provided ample depth for hauling bulky items like sheet goods or pallets, making it a practical choice for those who disliked the feeling of a long truck nose.
Standard Box: 6′ 6″ Bed
The 6-foot, 6-inch bed represented the standard and most popular configuration for the Sierra. This length struck a near-perfect balance between daily drivability and hauling capacity. It offered significantly more cargo space than the short box while remaining manageable for parking in average driveways and garages. This size is particularly well-suited for homeowners and DIY enthusiasts who regularly transport lumber, appliances, and other materials.
Long Box: 8′ Bed
For those who required maximum hauling capability, the 8-foot bed was the top-tier option. This length is the choice for professionals who need to transport long ladders, pipes, or building materials without overhanging dangerously. While it excelled at maximizing payload, it did require a longer wheelbase, which could impact turning radius and parking precision compared to the shorter variants.
Dimensions and Payload Impact
The physical dimensions of the bed directly correlate with the truck's overall capability. A longer bed typically utilizes a longer wheelbase, which contributes to higher towing stability and a smoother ride at highway speeds. Conversely, a shorter wheelbase enhances agility and reduces the visual gap between the cab and the tailgate, which some drivers prefer for aesthetic and practical reasons when loading tight spaces.
Towing and Hauling Synergy
It is crucial to consider the bed size in relation to the truck's towing package. A 2017 Sierra equipped with the powerful 6.2-liter EcoTec3 V8 engine generated significant towing power, but the bed length influenced weight distribution. Hauling a heavy trailer requires the mass to be positioned correctly to maintain traction; the correct bed ensures the cargo box length complements the tongue weight of the trailer, preventing sway and improving safety on the road.
