Find a Kenworth T800 Tri Axle Dump Truck for Sale Near You: The Ultimate Buyer’s Guide
If you’re searching for a “Kenworth T800 tri axle dump truck for sale,” you’re likely in the market for a heavyweight champion of construction and heavy hauling. This isn’t just any truck; it’s a legend on job sites, known for its brute strength, durability, and ability to handle the toughest assignments. Finding the right one, however, requires more than a quick online search. As someone who has spent over a decade crawling under rigs, talking with mechanics, and putting these machines through their paces, I’ve put together this comprehensive guide. We’ll dive into what makes the T800 special, where to look for a good deal, what to check before you buy, and how to ensure you’re getting a truck that will work as hard as you do.
Why the Kenworth T800 Tri Axle is a Top Performer
The Kenworth T800 is often called a “setback axle” truck, meaning its front axle is positioned further back than in conventional models. This design isn’t just for looks; it offers significant advantages for a dump truck operation. It provides superior weight distribution over the front axle, which is crucial when you’re carrying a heavy load. This setup also allows for a tighter turning radius, making it incredibly maneuverable on cramped construction sites and in urban areas where space is limited.

The tri-axle configuration adds another layer of capability. With three axles at the rear, the truck can legally carry more payload than a standard tandem-axle model. This directly translates to higher productivity and better profitability per trip. When you’re looking for a Kenworth T800 tri axle dump truck, you’re investing in a machine built for maximum efficiency and stability under load.
Key Features to Look For in Your T800 Dump Truck
Not all T800s are created equal. Over its long production run, various configurations were offered. Here’s what you should prioritize in your search for a used Kenworth T800 dump truck:
- Engine and Powertrain: Look for the Cummins ISX engine, a true workhorse in the industry. Paired with an 18-speed Eaton Fuller transmission, this combination delivers the torque and reliability needed for constant stop-and-go and steep grade work.
- Frame and Suspension: A high-tensile strength steel frame is non-negotiable. For the suspension, Hendrickson’s HAS air rear suspension is a popular and excellent choice, offering a smooth ride empty and exceptional stability when loaded.
- Cab Comfort and Condition: The T800’s cab was designed for driver comfort, which is key for retention and safety. Check for wear on the seats, the functionality of all controls, and any signs of water leaks or rust, especially around the sleeper area if equipped.
Where to Find a Kenworth T800 Dump Truck for Sale
Finding the right truck means looking in the right places. While national online classifieds are a good start, don’t overlook these sources:
- Regional Truck Dealers: Dealers that specialize in heavy-duty trucks often have well-maintained, trade-in units from fleet owners. They may also offer warranties.
- Industry-Specific Auctions: Auctions, both online and in-person, can be a source for good deals. Be prepared and do your homework on the specific truck’s history beforehand.
- Local Networking: Sometimes the best deals are never listed online. Talk to construction company owners, material suppliers, and other operators in your area. Word-of-mouth can lead you to a well-cared-for truck.
The Essential Pre-Purchase Inspection Checklist
Before you commit, a thorough inspection is critical. Here is a dump truck inspection checklist tailored for a used T800:
- Fluid Analysis: Get an oil sample analysis done. This can reveal hidden engine wear, coolant leaks, or other contaminants that aren’t visible to the naked eye.
- Frame and Body: Look for cracks, welds, or patches on the frame rails. Inspect the dump body for rust, especially in the corners and floor, and check the operation of the hoist and tailgate.
- Mechanical Components: Check for leaks around the differentials, transmission, and power steering. Inspect brake linings and drums for excessive wear. Jack the truck up and check for play in the wheel bearings.
- Test Drive: Listen for unusual noises, feel for any shimmies or vibrations, and test the engine brake and service brakes thoroughly under safe conditions.
