Understanding Dump Insert Specs: Dimensions, Capacity, and Fitment Explained

If you’re thinking about upgrading your pickup with a dump insert, understanding the specifications is essential. It’s not just about lifting power or material your insert needs to fit your truck, handle your loads, and work reliably in real-world job conditions.

At EZ-Dumper®, we offer both 6-foot and 8-foot dump inserts, designed to fit most short bed and full-size pickup trucks. But which one is right for you? The answer depends on more than just your bed length. You’ll want to consider volume capacity, payload limits, dump angle, and installation requirements before making a decision.

In this guide, we’ll walk through the complete specifications of our most popular dump inserts to help you choose the right setup for your workload and vehicle.

Why Specs Matter When Choosing a Dump Insert

Specs aren’t just numbers on a chart they directly affect how well your dump insert will perform day after day. If you choose the wrong fit, you could end up with limited capacity, reduced lift efficiency, or even unsafe operation.

Here’s what to consider:

Insert size and bed compatibility
Total payload and volume capacity
Weight of the insert itself
Dump angle and speed
Installation footprint and mounting requirements

By comparing each of these areas, you’ll get a clearer picture of how the EZ-Dumper® fits your truck and how it fits your goals.

EZ-Dumper® 8’ Dump Insert: Full-Size Power

The EZ0012T 8-foot steel dump insert is our most popular model, built for full-size pickups like the Ford F-250, RAM 2500, Chevy Silverado, and similar frames. It’s made from rugged 12-gauge steel flooring with 14-gauge steel sidewalls and includes full-length rub rails and expansion stake pockets for customization.

This model is ideal for contractors, landscapers, and municipalities handling heavy material loads and larger debris jobs.

Key Specs for 8’ Insert:

Bed Length: 96 inches
Unloaded Weight: 787 lbs
Payload Capacity: 6,000 lbs
Volume Capacity: 2 cubic yards
Dump Angle: 51 degrees
Mounting: Four bolt-down clamps on crossmembers
Power Source: Truck battery (12V)
Pump: Double acting Bucher Hydraulics system
Finish: Powder-coated black or 304 stainless steel
Tailgate: Removable, double-acting spreader-style

This model fits most 8-foot beds without modifications and can be installed in 2–3 hours using basic tools. The insert operates via a wired remote, raising to full angle in about 15 seconds.

For added volume, you can upgrade with side extensions and a cab protector, increasing total capacity to nearly 4 cubic yards with high-volume materials like mulch or brush.

EZ-Dumper® 6’ Dump Insert: Compact and Capable

Designed for today’s popular short bed pickups, the EZ0012TSB 6-foot model offers the same core features and power as the 8-foot version, in a more compact footprint. This insert fits trucks like the Ford F-150 SuperCab, Chevy Silverado 1500, RAM 1500, and similar 6.5-foot box models.

It’s the ideal choice for residential work, urban jobsites, and lighter-duty hauling that still demands high performance.

Key Specs for 6’ Insert:

Bed Length: 74 1/8 inches
Unloaded Weight: 691 lbs
Payload Capacity: 6,000 lbs
Volume Capacity: 1.5 cubic yards
Dump Angle: 51 degrees
Mounting: Four bolt-down clamps
Power Source: Truck battery (12V)
Pump: Double acting Bucher Hydraulics system
Finish: Powder coat black or 304 stainless
Tailgate: Removable, double acting spreader style

The 6’ model sacrifices a small amount of volume but retains full lifting strength and durability. It’s easier to maneuver in tight lots and urban work zones, making it a smart fit for landscaping crews or property managers.

Fitment Considerations: Will It Fit Your Truck?

EZ-Dumper® inserts are designed to fit most full-size and short-bed pickups, but it’s important to confirm:

Bed Length: The 6’ insert works in beds between 73–76 inches. The 8’ insert fits beds around 96 inches. Measure your truck bed from the front wall to the inside of the tailgate when closed.
Bed Style: Inserts are designed for traditional pickup beds, not stepsides or beds with major internal obstructions.
Payload Rating: Ensure your truck’s rear axle and suspension can handle the added weight of the insert and a full load. While the insert can lift 6,000 lbs, your truck needs to carry it safely.
Battery Access: The pump system connects directly to your 12V battery and draws power for lifting and lowering. Make sure your battery and alternator are in good condition.

If in doubt, your local EZ-Dumper® dealer can help confirm fitment and offer installation support.

What About Stainless Steel?

Both the 6’ and 8’ dump inserts are available in 304 stainless steel, offering the same specs but with added corrosion resistance. This material is especially valuable in:

Snow-heavy regions with salted roads
Coastal environments
High-moisture job sites like nurseries or concrete work

The stainless option is left uncoated (natural finish) and requires less maintenance over time. While it costs more upfront, it offers long-term durability with minimal upkeep.

Accessories That Enhance Specs

Certain accessories can improve or expand your insert’s performance:

Side Extensions: Increase volume to 3–4 cubic yards
Cab Protector: Improves safety when hauling debris
Tarp Kit: Helps secure and protect loads
Tailgate Spreader: Adds precision for gravel and soil placement

All accessories are available in steel or stainless and built to match your insert’s dimensions and finish.

Installation Footprint and Process

One of the greatest advantages of EZ-Dumper® inserts is their straightforward installation. No cutting, drilling, or welding is required. The unit drops directly into the truck bed and clamps down using the included hardware.

Average install time: 2–3 hours
No permanent bed modification required
Mounts to crossmembers using included bolt-down clamps
Pump and hydraulic cylinder are pre-installed under the insert

Each unit comes with detailed instructions and diagrams. Most customers install them in-shop or at the dealer, but DIY installation is also possible for mechanically inclined owners.

Helping You Choose the Right Model

Still unsure which insert fits your needs? Here are some basic recommendations:

Choose the 6’ model if you:

Drive a short-bed pickup (typically 6.5 feet)
Work in residential or tight access areas
Haul lighter, bulkier material like mulch, chips, or compost
Need a lower overall unit weight

Choose the 8’ model if you:

Drive a full-size long bed pickup (8 feet)
Haul construction debris, stone, dirt, or heavier loads
Need the most volume per trip
Want to reduce trips and maximize dump capacity

Either way, you’re getting EZ-Dumper® quality designed, manufactured, and supported in the USA since 1972.
