Before you tow: important considerations

To ensure safe and reliable towing with a GX470, consider these precautions and preparations before hitting the road.

• Confirm the vehicle has a compatible towing package and a hitch rated for up to 6,500 pounds braked.


• Use a proper braking setup on the trailer (braked trailer preferred) and, if applicable, a brake controller in the tow vehicle.


• Assess the payload and tongue weight to stay within limits; distribute weight carefully on the trailer.


• Use a weight-distribution hitch with sway control for larger trailers to improve stability.


• Inspect and, if needed, upgrade cooling components (radiator, transmission cooler) to handle the extra heat from towing.


• Check tires, brakes, and suspension wear; ensure tires have appropriate load ratings for towing.

In short, preparation is key. Proper equipment and maintenance make a noticeable difference in safety and reliability when towing with the GX470.

Payload and hitching considerations

Understanding payload, tongue weight, and hitch options helps you tow more confidently. The GX470’s payload capacity is affected by the vehicle’s weight and equipment; always verify the exact figures for your specific unit. When hitching, aim for a tongue weight of roughly 10-15% of the trailer’s gross weight and ensure your hitch and ball mount are rated for the full braked capacity of the trailer.

Maintenance and reliability considerations

Because the GX470 is an older model, maintenance history matters more for towing reliability. Regularly service fluids, cooling components, and braking systems to keep towing performance consistent. If a GX470 has seen heavy use or high miles, pay extra attention to transmission cooling, hose integrity, and brake wear, as towing adds stress to these systems.

Common issues to watch in aging GX470s

While many GX470s remain dependable, aging components can surface as mileage climbs. Look for a well-documented service history, and be mindful of typical wear items—brakes, suspension bushings, hoses, and cooling system components—that can affect towing performance and reliability.

Alternatives for heavier or more frequent towing

If you tow heavier loads regularly or plan to tow long distances with frequent trips, you may want to compare with more capable options that are purpose-built for heavy-duty towing, such as full-size SUVs and trucks from the Toyota/Lexus family (e.g., Sequoia), or competing models from other brands in the same class. These can offer higher tow ratings, more modern trailer-assist technologies, and newer safety systems.

Bottom line

The GX470 offers solid towing capability for an aging luxury SUV, with an official braked capacity of up to 6,500 pounds when properly equipped. It excels for occasional to moderate towing tasks, especially when well-maintained and paired with appropriate trailer equipment. For heavy, frequent towing or for modern towing conveniences and safety features, consider newer models or larger platforms designed specifically for higher-duty towing.

Summary: The Lexus GX470 remains a viable option for towing lighter to mid-size trailers, boats, and campers within its 6,500-pound limit. Its combination of a robust V8, stable ride, and space makes it capable, provided you keep up with maintenance and equipment and stay within rated limits. For ongoing heavy-duty towing, evaluate newer, more capable alternatives.

Can you tow with a GX 470?

If you do ever happen to blow one up, you can find a replacement in any GX470, LX470, Landcruiser (99-07), and a bunch of 4Runners (03-09). All of these vehicles share the same 6500-lbs tow capacity from the factory.

What is the 80% rule for towing?

The 80% rule for towing is a safety guideline that recommends the weight of a fully loaded trailer should not exceed 80% of a vehicle's maximum towing capacity. This provides a safety margin for unpredictable conditions and reduces stress on the vehicle's engine, transmission, and brakes, helping to ensure better handling and a longer lifespan for components.
 
How it works

• Calculate your vehicle's limit: Find your vehicle's maximum towing capacity in the owner's manual or on the manufacturer's website. 
• Calculate 80% of the limit: Multiply the maximum towing capacity by 0.800.800.80 to find your safe towing limit. For example, if your vehicle can tow 10,00010 comma 00010,000 pounds, your limit is 8,0008 comma 0008,000 pounds. 
• Account for all weight: Ensure the total weight of the fully loaded trailer, including cargo and passengers in both the vehicle and the trailer, stays below this 80% limit. 

Why it's important

• Safety margin: It provides a buffer for real-world factors like hills, curves, and sudden stops. 
• Vehicle longevity: It reduces strain on key components like the engine, transmission, and brakes, which can extend their lifespan. 
• Handling: Maintaining a margin helps ensure your vehicle can be steered and controlled effectively, even under load.
