GNSB 84″ × 100″ Aluminum Flatbed – SRW Long Bed (2278)

The GNSB Model 2278 aluminum truck bed is designed for pickup owners looking to replace a traditional cargo box with an open flatbed. Measuring 84 inches wide and 100 inches long, this single-rear-wheel, long-bed configuration is advertised for select Ford, Chevrolet/GMC, and Dodge/Ram pickups.

What makes this model worth considering is its combination of aluminum construction, a third brake light, and a sliding-window cutout. These details give buyers more to evaluate than platform dimensions alone, particularly when planning a replacement bed for a working pickup.

GNSB Aluminum Truck Bed – 84″ × 100″ Dimensions

The GNSB 2278 measures 84 inches across and 100 inches in length, giving buyers a clearly defined size when comparing replacement flatbeds.

At 7 feet wide, the platform offers an open loading surface for suitable work materials and equipment. Its 100-inch length provides another important measurement when considering the overall body configuration.

The model is listed as a long-bed application for single-rear-wheel pickups. These specifications should be compared with the intended vehicle before ordering.

Aluminum Construction for Everyday Truck Use

Aluminum is a popular material for replacement truck bodies because it offers corrosion resistance and can provide weight advantages over comparable steel designs.

For owners who use their pickups outdoors, material choice can be especially important. Exposure to rain, road conditions, and regular worksite use all influence how a truck body ages.

The GNSB 2278 uses aluminum construction, making it an option for buyers who specifically prefer an aluminum replacement bed rather than a steel alternative.

Actual weight and load capacity depend on the completed bed design and vehicle specifications.

Third Brake Light Feature

The GNSB Model 2278 is listed with a third brake light.

A third brake light provides an additional rear-facing brake signal, helping other drivers recognize when a vehicle is slowing or stopping.

This is a useful detail to consider when replacing a factory pickup bed, especially because lighting arrangements can differ between original truck bodies and aftermarket replacements.

Buyers should ensure the completed installation meets the vehicle’s applicable lighting requirements.

Sliding-Window Cutout

Another distinguishing feature of the GNSB 2278 is its sliding-window cutout.

This cutout is intended to accommodate the rear-window area on suitable truck configurations. It is particularly relevant when considering clearance around a pickup’s sliding rear window.

For buyers whose trucks have this window arrangement, the cutout is an important feature to review when comparing replacement bodies.

The final position and clearance should be checked against the specific cab and window configuration.

Single-Rear-Wheel Long-Bed Configuration

The GNSB 2278 is identified as a single-rear-wheel (SRW) long-bed model.

SRW trucks use one rear wheel on each side of the rear axle, while dual-rear-wheel trucks have paired rear wheels.

This distinction matters because the body arrangement and wheel clearance requirements can differ.

The GNSB’s 84″ × 100″ dimensions and SRW designation help buyers narrow their search when comparing flatbeds for long-bed pickups.

Open Access for Work Materials and Equipment

A traditional pickup box has fixed sides that help contain cargo. An open flatbed changes how materials can be approached and loaded.

With an open platform, suitable items can be loaded or accessed from the sides and rear, which can be helpful when handling bulky supplies.

For contractors, property owners, and other pickup users, this arrangement may make certain loading tasks more convenient.

The GNSB aluminum truck bed provides this open-bed layout while retaining the specific dimensions and features associated with Model 2278.

All materials must be properly secured and kept within the truck’s rated carrying limits.

Advertised Ford, Chevrolet/GMC, and Dodge/Ram Applications

The GNSB Model 2278 is advertised for select Ford, Chevrolet/GMC, and Dodge/Ram pickup applications.

Because these manufacturers offer different chassis, cab, and bed configurations, compatibility should be established using the exact truck model and year.

The SRW long-bed designation, overall dimensions, and sliding-window cutout are important details to consider during that process.
