2026 Lexus GX 550 Towing Capacity and Off-Road Capability
The 2026 Lexus GX 550 tows up to 9,096 pounds on the Overtrail grade when properly equipped. The Premium, Premium+, and Overtrail+ grades are rated at 9,063 pounds. Every GX 550 also leaves the factory with full-time four-wheel drive, a tow hitch receiver, and an integrated trailer brake controller. The tow hardware is built in, not added later.
Lexus builds the GX on the GA-F platform introduced on the current-generation LX. This ladder frame resists twisting off-road forces. It also keeps wheel articulation stable and tire contact consistent over uneven ground. Those same qualities keep the vehicle settled under a heavy trailer. Power reaches the ground through a Torsen limited-slip locking center differential, standard on every GX 550. It splits engine output 50:50 front to rear. That helps prevent wheel spin on low-grip surfaces such as a wet launch ramp.
How Much Can the 2026 Lexus GX 550 Tow?
Towing capacity varies by grade, and the Overtrail carries the highest rating in the lineup. The figures below are published by Lexus in its 2026 GX model-year release.
| Grade | Maximum Towing (Properly Equipped) | Seating |
|---|---|---|
| Overtrail | 9,096 lbs | 5 (two rows) |
| Premium | 9,063 lbs | Up to 7 |
| Premium+ | 9,063 lbs | Up to 7 |
| Overtrail+ | 9,063 lbs | 5 (two rows) |
| Luxury | Rated lower — see note | Up to 7 |
| Luxury+ | Rated lower — see note | Up to 7 |
Note: Lexus does not state towing figures for the Luxury and Luxury+ grades in its 2026 model-year release, and independent published figures for those two grades disagree with one another. Both are rated lower than the Premium and Overtrail grades. Confirm the rating for a specific configuration with our sales team before purchasing a trailer.
Standard Towing Hardware
An integrated trailer brake controller is standard on all six grades. It lets you tune braking force to the trailer instead of relying on the tow vehicle alone. That matters most when a load approaches the maximum rating. A tow hitch receiver is standard as well, and Lexus describes the Overtrail’s 9,096-pound rating as best in class.
Maximum towing and payload capacity figures are based on properly equipped vehicles and vary by configuration. Do not exceed any weight rating. See your owner’s manual and the vehicle’s door-jamb label for specific capacities.
What Engine Powers the 2026 Lexus GX 550?
Every 2026 GX 550 runs a twin-turbocharged 3.4-liter V6. It makes 349 horsepower and 479 lb-ft of torque. Lexus pairs it with a 10-speed Direct Shift automatic transmission and standard full-time four-wheel drive.
The engine replaces the naturally aspirated 4.6-liter V8 of the previous-generation GX 460. That V8 produced 301 horsepower and 329 lb-ft. The V6 gains 48 horsepower and 150 lb-ft on those figures. Where the torque arrives matters more for towing than the peak number. The twin-turbo V6 hits its 479 lb-ft peak at 2,000 rpm. Merging onto the freeway with a trailer does not require winding the engine out.
| Specification | 2026 Lexus GX 550 |
|---|---|
| Engine | 3.4L twin-turbocharged V6 |
| Horsepower | 349 hp |
| Torque | 479 lb-ft at 2,000 rpm |
| Transmission | 10-speed Direct Shift automatic |
| Drivetrain | Full-time four-wheel drive, two-speed transfer case |
| Center differential | Torsen limited-slip locking, 50:50 split |
| EPA-estimated fuel economy | 15 city / 21 highway / 17 combined |
EPA-estimated fuel economy figures are for comparison purposes only. Your actual mileage will vary depending on driving conditions, how you drive and maintain your vehicle, battery age/condition, and other factors.

What Off-Road Features Does the GX 550 Overtrail Offer?
Ground Clearance and Off-Road Geometry
The Overtrail and Overtrail+ grades include a standard one-inch suspension lift. It raises minimum running ground clearance to 9.84 inches. The other four grades measure 8.66 inches. Both Overtrail grades ride on 18-inch alloy wheels wrapped in 33-inch all-terrain tires. Both also include an onboard air compressor and prewired auxiliary switches as standard equipment.
| Measurement | Overtrail & Overtrail+ | Premium, Premium+, Luxury, Luxury+ |
|---|---|---|
| Minimum running ground clearance | 9.84 in | 8.66 in |
| One-inch suspension lift | Standard | Not offered |
| Wheels and tires | 18-in alloy, 33-in all-terrain | 20-in or 22-in alloy |
| Approach angle | Up to 26 degrees | |
| Breakover angle | Up to 24 degrees | |
| Departure angle | Up to 21 degrees | |
Note: Approach, breakover, and departure angles are the maximum figures Lexus publishes for the GX line and are not broken out by grade. Angles vary with running boards, hitch hardware, and other equipment.
Electronic Kinetic Dynamic Suspension System (E-KDSS)
The centerpiece of the Overtrail hardware is E-KDSS. The system electronically locks and unlocks the front and rear stabilizer bars. It can act on each end independently. It responds to driving conditions, vehicle speed, steering input, and the chosen Multi-Terrain Select mode. Unlocking the bars lets a wheel drop further into a rut and hold contact with the ground. Back on pavement, the bars lock in again to control body roll.
Off-Road Hardware Standard on Overtrail Grades
Electronic Locking Rear Differential
Activated by a console-mounted switch, it splits power evenly between the left and right rear wheels to help them turn at the same speed.
Multi-Terrain Select
Adjusts drive power, brake pressure, and suspension response to match the surface.
Crawl Control
Engages in low range and manages engine output and brake pressure at one of five driver-selected low speeds.
Multi-Terrain Monitor
Four cameras display underfloor, front, side, and rear views on the 14-inch touchscreen.
Seating and Cargo Space
Seating layout tracks with the grade family. It also changes how much gear fits behind the seats. The Overtrail and Overtrail+ are two-row, five-passenger vehicles. Dropping the third row gives them more room than the seven-passenger grades once the rear seats fold. That matters for recovery gear and camping equipment.
| Cargo Volume | Overtrail & Overtrail+ (two-row) | Premium, Premium+, Luxury, Luxury+ (three-row) |
|---|---|---|
| Behind the third row | Not applicable | 10.3 cu ft |
| Behind the second row | 45.6 cu ft | 40.2 cu ft |
| Behind the front row (rear seats folded) | 90.5 cu ft | 76.9 cu ft |
Buyers who need seven-passenger seating can choose the Premium, Premium+, Luxury, or Luxury+ grades. Those grades keep full-time four-wheel drive and the locking center differential. They do not offer E-KDSS or the locking rear differential. For a closer look at the trail-focused grade, read our 2026 Lexus GX 550 Overtrail review.
Taking the GX 550 Off Pavement
Low-Range Driving Aids
Low-range four-wheel drive, Multi-Terrain Select, and Crawl Control matter most once the pavement ends. Crawl Control works in low range. It moves the vehicle forward or in reverse at one of five driver-selected speeds. It manages engine output and brake pressure to reduce tire slip. On a loose descent, the driver steers while the vehicle handles the throttle and brakes.
Multi-Terrain Select adjusts drive power, brake pressure, and suspension response to match the surface. The available modes differ between high range and low range.
| Range | Multi-Terrain Select Modes |
|---|---|
| High range (H4) | Auto, Dirt, Sand, Mud, Deep Snow |
| Low range (L4) | Auto, Sand, Mud, Rock |
With the system active, the Multi-Terrain Monitor draws on four cameras from the Panoramic View Monitor. It shows underfloor, front, side, and rear views on the 14-inch touchscreen. That helps judge clearance over obstacles the driver cannot see from the seat.
Highway Driving to the Trailhead
For drivers heading out of Temecula, Murrieta, or Corona toward the Santa Ana Mountains, the drive to a trailhead is usually the longest part of the day. Lexus Safety System+ 3.0 is standard on every GX 550. It includes Lane Tracing Assist and full-speed Dynamic Radar Cruise Control for those highway miles.
Common Questions About 2026 Lexus GX 550 Towing and Off-Road Capability
Does the 2026 Lexus GX 550 come standard with a trailer hitch and brake controller?
Yes. Every 2026 GX 550 includes a standard tow hitch receiver, and an integrated trailer brake controller is standard equipment across all six grades. The controller lets drivers adjust braking force to the trailer, which matters most when a load approaches the vehicle’s maximum rating.
How does the Electronic Kinetic Dynamic Suspension System operate off-road?
E-KDSS electronically locks and unlocks the front and rear stabilizer bars, and can act on each end independently based on driving conditions, speed, steering input, and the selected Multi-Terrain Select mode. Unlocking the bars increases wheel articulation over rocks and ruts so the tires stay in contact with the terrain. Back on pavement, the system locks the bars to limit body roll.
Does the Lexus GX 550 Overtrail offer a third row?
No. The Overtrail and Overtrail+ are configured as two-row, five-passenger vehicles. That layout gives them 45.6 cubic feet behind the second row and 90.5 cubic feet with the second row folded. Buyers who need seven-passenger seating can select the Premium, Premium+, Luxury, or Luxury+ grades.
What differentials does the GX 550 use?
A Torsen limited-slip locking center differential is standard on all 2026 GX 550 grades and splits engine power 50:50 front to rear. The Overtrail and Overtrail+ grades add an electronically controlled locking rear differential, activated by a console-mounted switch, which splits power evenly between the left and right rear wheels to help them turn at the same speed.
