2018 Kenworth T880 Triaxle Roll Off Heavy Spec 8LL: Heavy Spec and the 8LL Question

A 2018 Kenworth T880 triaxle roll off heavy spec is a Class 8 roll-off truck with a triaxle chassis and a heavier-duty build in the frame, axles, suspension, and driveline; the 8LL reference often shows up in searches and listings, but that manual transmission is commonly tied to a similar T800 and is not standard on the T880. The T880 itself is a working truck first and a spec sheet second, built to haul containers, swap boxes quickly, and stay productive on construction, waste, and environmental routes, so the exact spec matters if you are judging capacity, hoist setup, driveline fit, and day-to-day reliability.

For equipment owners, fleet managers, contractors, dealers, and companies comparing or marketing used heavy equipment trucks, the details here are the parts that affect a buying, selling, or inspection decision. What follows is drawn from available listing and specification material on T880 roll-offs, including a Kenworth T880 walkaround, a build feature, and dealer inventory listings, with a focus on heavy spec package details, transmission options and where 8LL fits, used-market pricing, inspection points, and how online marketplaces help buyers and sellers sort out real truck spec from shorthand in a listing. Where the source material does not settle a detail, such as the exact transmission in a specific truck, this article says so rather than guessing.

What a Kenworth T880 triaxle roll off actually is

The T880 is a Class 8 chassis, and in roll-off service it carries a hoist assembly on the frame rails behind the cab. Containers, often called bins or boxes, slide onto the rails and are winched or hydraulically drawn aboard. A walkaround description of a T880 roll-off in the source material labels the setup a 12-wheeler in a roll-off configuration, which is the typical triaxle arrangement: one steer axle up front and tandem plus tag or tridem axles at the rear carrying the weight of the loaded container.

The T880 platform's reputation is part of the appeal. A 2017 article on the truck reports that Kenworth described the T880 as the most versatile vehicle to ever roll off its assembly line. It was designed for multiple chassis configurations to fit demanding vocational applications and different kinds of work across fleet operations.

Its modular chassis also supports various vocational body integrations.

Reading heavy spec and Hendrickson air suspension on a roll-off truck

Heavy spec is not a single option code. It is a package of choices that usually touches the frame, the axles, the suspension, the hoist, and the driveline. On a roll-off, the practical question is whether the truck can handle the containers you plan to haul, day after day, while hauling heavy materials for demanding work without the frame or the hoist taking the punishment.

The areas worth confirming on any heavy spec listing include:

• Hoist capacity and manufacturer, since the hoist rating drives which container sizes and loaded weights are appropriate.

• Frame rail condition, including any cracks, repairs, or stretched sections around the hoist mounts.

• Axle and suspension ratings, plus the truck's configured weight ratings as ordered.

• Body dimensions and tailgate type, because container compatibility depends on rail length and lock placement.

• Engine model, horsepower rating, and transmission, which together determine how the truck starts a loaded container on a grade.

Some heavy-spec roll-offs are equipped with full air-brake systems and ABS for demanding vocational applications such as waste management and construction debris removal.

The source material shows how much these trucks vary. A build feature on a T880 lists a 17 ½ ft PikRite lightweight steel body with a high lift tailgate, a Paccar MX-13 engine rated at 510 HP, and an Eaton 18-speed transmission. A separate used listing for a T880 roll-off references a triaxle configuration with a 75,000 American Roll-Off hoist. Another listing shows a T880 roll-off with a Cummins engine at 500 HP and a 6-speed transmission. Each of those is a different truck built for a different job, and that range matters for buyers in different industries who need reliability.

Specs shown in current listings

The table below summarizes configurations that appear in the available listing and feature material. It is a comparison of what sellers and builders have published, not a specification for every T880 ever built. Current listings and build material also show different powerful engine options and performance profiles, so published features can vary by truck and available options.

Read the table as a warning about assumptions rather than a buyer's guide to one model year. Two T880 roll-offs sitting side by side can have completely different engines, gearboxes, and hoists. Other T880 configurations may use a Cummins X15 rated from 450 to 600 horsepower with up to 2,050 lb-ft of torque, or a 425hp ISX 12L, depending on the truck.

Where the 8LL fits in vocational applications

The 8LL tag in the topic refers to a manual transmission designation that shows up on heavy vocational trucks, and in the source material it appears on a Kenworth T800 tri axle roll off paired with a Caterpillar engine rated at 430 HP. The T880 listings in the same material show an Eaton 18-speed and a 6-speed instead. That is the key point for anyone shopping a "T880 triaxle roll off heavy spec 8LL": the 8LL is a transmission choice, not a feature that comes automatically with the T880 badge or with a triaxle chassis. The Eaton Fuller 8LL has 8 forward speeds and 2 low-range ratios.

Transmission choice matters on a roll-off because the truck spends its life starting heavy loads from a stop, working hydraulic power take-off equipment, and maneuvering in tight transfer stations or job sites. A manual gearbox with deep-reduction gearing allows precise low-speed control in demanding vocational work, and it can be rebuilt by many independent shops. It also assumes you have drivers who are comfortable with a clutch and a shift pattern, which is a real staffing question for many fleets today.

Before committing to any truck described as an 8LL, confirm the exact transmission model, the rear axle ratios, the rated capacity, whether it runs, and how many speeds are listed if a seller uses shorthand. Listing shorthand and builder language do not always match.

Price signals in the used roll-off market

Prices in the available material span a wide band. A T880 roll-off with a Cummins engine at 500 HP and a 6-speed is listed at $228,795 USD. A new 2027 Kenworth roll-off shown as a Class 8 truck is listed at $267,500. A T800 tri axle roll off with the Caterpillar and 8LL combination is listed as call for price. At least one used T880 roll-off listing quotes a $5,000 rental figure rather than a sale price, which is a reminder that listing language varies from seller to seller, that advertised pricing may exclude tire and documentation fees, and that the number in a title is not always the purchase price.

Treat every figure as a starting point for a conversation. Condition, hours, mileage, hoist brand, and the container package included with the truck move the final number far more than the model year alone. Ask for the full build sheet and recent service records before you compare two trucks on price.

Some dealers also offer financing, including loans or leases for the T880, making the purchase process easier to match to cash flow. Financing specialists can tailor options to business needs; when gathering information, buyers may also come across PACCAR Financial deferred-payment programs and Wallwork Truck Center financing solutions.

What to inspect on a used T880 triaxle roll off

A roll-off truck earns its money by carrying weight it did not carry when it left the factory as a bare chassis. The inspection should follow that stress path.

1. Walk the frame rails front to back with a light. Look for cracks, previous welds, and distortion near the hoist mounts and the rear axles, especially on a truck that has been put to work in waste management or construction debris removal.

2. Cycle the hoist through a full raise and lower. Watch for smooth travel, listen for pump noise, and check every hydraulic line and cylinder for weeping.

3. Inspect the rails, rollers, and locks that guide the container. Worn rollers make loading difficult and can damage containers over time.

4. Check the tailgate and any tarp or cover system if the truck has one, since a high lift tailgate is only useful if it operates correctly.

5. Verify the transmission model and axle ratios against the build sheet rather than taking the listing title at face value.

6. Review engine hours, mileage, and service history for the engine, transmission, and rear ends. Confirm the front axle, hendrickson air suspension, and tires match the stated specs.

7. Confirm the hoist capacity and the container sizes you intend to run, and match them to the truck's weight ratings. That matters most when the truck is expected to handle demanding vocational applications.

Why buyers and sellers use a marketplace

Roll-off trucks are regional machines, and the right one is often several states away. Ironmartonline is a web-based marketplace that connects buyers and sellers of used heavy equipment, trucks, and machinery, with sellers able to list across nine platforms to reach a broad buyer audience and no contracts or hidden fees on the seller side. For buyers, that means a broader marketplace where they can find a T880 triaxle roll-off that fits the job and their location more easily instead of taking whatever is sitting on the nearest lot. Listings may also include VIN and more information for buyers comparing trucks across locations, including markets such as Naples.

Learn about available features, configuration options, and financing before you start calling on listings. A heavy spec T880 triaxle roll off with the right hoist and the right gearbox is a long service truck. One ordered for a lighter duty cycle can become an expensive lesson. Confirm every specification with the seller and, where the stakes are high, with an independent inspection before money changes hands.

Frequently Asked Questions

Does every Kenworth T880 triaxle roll off come with an 8LL transmission?

No. Available listing material shows T880 roll-offs with an Eaton 18-speed and with a 6-speed, while the 8LL designation appears on a T800 tri axle roll off in the same material. Some sellers also note how a truck runs, but the transmission and exact number of speeds still need to be verified on each listing rather than treated as a standard feature of the model.

What does heavy spec mean on a roll-off truck?

It is shorthand for a build ordered with heavier ratings and components, and heavy spec usually covers the frame, front axle, rear axles, suspension, braking equipment, and hoist, depending on how the truck was ordered. There is no single definition, so ask the seller for the build sheet and confirm the hoist capacity, weight ratings, and suspension details—sometimes including Hendrickson air suspension on some listings—before you buy.

How much does a used Kenworth T880 roll off cost?

Listing figures in the available material range from $228,795 for a T880 roll-off with a Cummins engine and 6-speed to $267,500 for a new 2027 Kenworth roll off shown as Class 8. Some listings quote call for price or a rental rate instead of a sale price, so confirm the actual selling price, included fees, and available financing options directly with each seller.

What should I check first on a used triaxle roll off?

Start with the frame rails and the hoist. Cracks or previous repairs around the hoist mounts are the most expensive problems to fix, and a hydraulic system that weeps or cycles roughly signals further cost. Then verify the transmission, axle ratios, and hoist capacity against the build sheet, and confirm tires condition and axle ratings as part of the first inspection pass.

Can a T880 roll off handle the same containers as a larger roll-off truck?

Container compatibility depends on rail length, lock placement, tailgate type, hoist rating, and how the truck was designed to fit the containers you plan to haul rather than the model name alone. A build feature in the source material lists a 17 ½ ft PikRite lightweight steel body with a high lift tailgate, which shows how specific these dimensions get. Measure your containers and match them to the truck.
