How Much Can a Toyota 4Runner Tow: Towing Capacity, Specs & Limits
The Toyota 4Runner is a legendary icon in the off-road automotive world, revered for its bulletproof durability, rugged body-on-frame truck architecture, and go-anywhere four-wheel-drive prowess. For outdoor adventure enthusiasts, camping families, and weekend boaters, the 4Runner is an enticing adventure companion. However, before hitching up a travel trailer, pontoon boat, or dual-axle horse trailer, understanding the exact towing limits of your vehicle is vital. Towing exceeds simply bolting a ball to the receiver; it involves understanding factory gross vehicle weight ratings (GVWR), tongue weight thresholds, transmission cooling limits, and payload calculations.
Fifth-Generation (2010 - 2024) Towing Capacity: 5,000 Pounds
For the beloved 5th-generation Toyota 4Runner (spanning model years 2010 through 2024), the maximum conventional towing capacity is exactly 5,000 pounds across all trim levels—including SR5, TRD Off-Road, TRD Pro, and Limited models.
Powering the 5th-generation 4Runner is Toyota legendary 4.0-liter naturally aspirated 1GR-FE V6 engine, generating 270 horsepower and 278 lb-ft of torque mated to a heavy-duty 5-speed automatic transmission. Every 5th-gen model comes factory-equipped with an integrated Class III/IV frame-mounted tow hitch receiver and a 4-pin/7-pin trailer wiring harness.

Sixth-Generation (2025+) Towing Capacity: Up to 6,000 Pounds
With the release of the all-new 6th-generation 2025 Toyota 4Runner built on the modern TNGA-F global truck platform (shared with the Tacoma, Land Cruiser, and Tundra), Toyota upgraded powertrain capabilities significantly.
Standard 2025+ models powered by the turbocharged 2.4-liter i-FORCE inline-four engine (278 horsepower and 317 lb-ft of torque) achieve a maximum towing capacity of 6,000 pounds—a 1,000-pound increase over the previous generation. The high-performance i-FORCE MAX hybrid powertrain (generating 326 horsepower and an enormous 465 lb-ft of torque) is rated to tow up to 6,000 pounds on select trims, expanding camping trailer options.
Evaluating realistic real-world trailers and recreational toys you can safely tow behind a 5,000-pound rated Toyota 4Runner.
| Trailer Type / Cargo | Typical Dry Weight | Loaded Wet Weight (with Gear/Water) | Can a 4Runner Tow It Safely? |
|---|---|---|---|
| Pop-Up Tent Camper | 1,500 to 2,500 lbs | 2,200 to 3,200 lbs | Yes; effortless towing with minimal wind drag |
| Single-Axle Teardrop Camper | 1,200 to 2,000 lbs | 1,800 to 2,600 lbs | Yes; excellent fuel economy and stability |
| Small Travel Trailer (16 - 20 ft) | 2,800 to 3,800 lbs | 3,800 to 4,800 lbs | Yes; requires WDH and electronic brake controller |
| Bowrider Ski Boat (18 - 21 ft) | 2,500 to 3,500 lbs | 3,500 to 4,500 lbs | Yes; excellent ramp pulling with 4WD low range |
| Dual Jet Ski Trailer | 800 lbs (Trailer) | 2,000 to 2,600 lbs (Loaded) | Yes; light load, easy towing |
| Large Dual-Axle Camper (25+ ft) | 5,000 to 6,500 lbs | 6,500 to 8,000+ lbs | NO; dangerously exceeds 4Runner towing & payload limits |
Tongue Weight and the Critical Payload Limitation
A common towing trap for 4Runner owners is focusing solely on the 5,000-pound trailer pull rating while ignoring tongue weight and vehicle payload. Maximum allowable tongue weight (the downward vertical force exerted on the hitch ball) is 10 percent of the tow rating: exactly 500 pounds for 5th-gen models and 600 pounds for 6th-gen models.
Crucially, tongue weight counts directly against your vehicle available payload capacity (typically 800 to 1,200 pounds on a 4Runner). If your tongue weight is 500 pounds, you have only 300 to 700 pounds of remaining payload for driver, passengers, roof rack cargo, and camping gear inside the cabin before dangerously exceeding GVWR.
Essential Towing Upgrades: Brake Controllers and Weight Distribution
To tow safely near the 5,000-pound threshold, several aftermarket upgrades are strongly recommended. While the 4Runner has a factory 7-pin connector, it does not come with an integrated electronic trailer brake controller from the factory; installing a proportional brake controller (such as a Redarc Tow-Pro Elite or Tekonsha Prodigy P3) is legally required for trailers over 1,500 to 3,000 pounds depending on state law.
Additionally, utilizing a Weight Distribution Hitch (WDH) with integrated sway control prevents rear-end suspension sagging, levels vehicle headlights, and keeps critical front-tire steering traction firmly planted on the pavement.
How to Prepare Your Toyota 4Runner for Safe Towing
Step-by-step practical guide to setting up your 4Runner for towing camping trailers or boats.
Install a Proportional Trailer Brake Controller
Plug an aftermarket brake controller (such as Redarc Tow-Pro) into the factory pre-wired harness plug located under the drivers dash.
Check Vehicle and Trailer Tongue Weights
Use a specialized tongue weight scale to verify tongue load is between 10% and 12% of total trailer weight and under 500 lbs.
Equip a Weight Distribution Hitch (WDH)
For travel trailers over 3,500 lbs, install a weight distribution hitch with built-in sway control to eliminate rear suspension sag.
Tow in S4 (Sport Mode) to Protect Transmission
Shift your 5-speed automatic transmission into S4 on the highway; avoid overdrive 5th gear to prevent transmission hunting and fluid overheating.
Increase Cold Tire Pressures to Max Load Spec
Inflate rear tires to the maximum cold PSI listed on the tire sidewall (typically 35 to 44 PSI) to stiffen sidewalls and prevent trailer sway.
Frequently Asked Questions (8 Questions Answered)
Q1: What is the towing capacity of a Toyota 4Runner?

Q3: Does the 4Runner have a factory transmission cooler?
Yes, 5th-gen 4Runners come equipped with a factory auxiliary transmission fluid cooler integrated into the radiator assembly.
Q4: What is the maximum tongue weight on a 4Runner?
Maximum allowable tongue weight is 500 pounds on 5th-generation models and 600 pounds on 2025+ 6th-generation models.
Q5: Which Toyota 4Runner towed the most in history?
The 4th-generation (2003-2009) 4Runner equipped with the optional 4.7-liter V8 engine had a massive factory tow rating of 7,300 pounds.
Q6: Do you need a weight distribution hitch on a 4Runner?
Toyota recommends a weight distribution hitch for trailers over 5,000 pounds, but using one for any trailer over 3,500 pounds prevents dangerous rear sag.
Q7: Can a 4Runner tow a boat?
Yes, bass boats, ski boats, and center consoles up to 21 feet on single or tandem trailers (3,000 to 4,500 lbs) tow easily.
Q8: Why does my 4Runner gear hunt when towing?
In Drive (5th gear overdrive), the transmission shifts constantly to maintain torque; shifting into 4th gear (S4) stabilizes engine RPM and cools fluid.
