Factory Towing Numbers
The Gladiator is marketed with an impressive 7,650 lb maximum towing capacity. But that number comes with significant asterisks, and it drops quickly when you start modifying.
Towing Capacity by Trim
| Trim/Configuration | Max Towing | Payload |
|---|---|---|
| Sport S (Max Tow Package) | 7,650 lbs | 1,700 lbs |
| Sport S (Standard) | 4,500 lbs | 1,600 lbs |
| Rubicon | 7,000 lbs | 1,200 lbs |
| Mojave | 6,000 lbs | 1,270 lbs |
The Max Tow Package includes a 4.10 axle ratio, trailer hitch, and integrated brake controller. It's required for maximum capacity.
What Modifications Do to Towing
Lift Kits
Any lift affects towing capacity, though manufacturers rarely publish specific numbers. Here's what happens:
- Higher center of gravity reduces stability
- Changed geometry affects weight distribution
- Steering can become less precise under load
Rule of thumb: Reduce rated towing by 10-15% per 2" of lift.
Larger Tires
Bigger tires have significant effects on towing:
- Increased rotating mass strains transmission
- Lower effective gear ratio reduces pulling power
- Larger contact patch increases rolling resistance
Rule of thumb: Every 2" increase in tire diameter reduces effective towing capacity by approximately 500-750 lbs.
Added Weight
Every pound of accessories you add comes directly off your payload and affects towing. Common additions:
- Steel bumpers: 80-150 lbs each
- Winch: 70-100 lbs
- Rock sliders: 60-100 lbs
- Roof rack: 30-60 lbs
- Skid plates: 40-80 lbs
- Spare tire upgrade: 20-40 lbs
A moderately built Gladiator easily adds 400-600 lbs of accessories.
Real-World Modified Towing Capacity
Here's what owners actually report safely towing after modifications:
| Setup | Comfortable Towing |
|---|---|
| Stock | 6,000-7,000 lbs |
| 2" lift, 35" tires | 5,000-6,000 lbs |
| 3" lift, 37" tires, steel bumpers | 4,000-5,000 lbs |
| 4"+ lift, 40" tires, full armor | 3,000-4,000 lbs |
Towing Performance Tips
Regear for Towing
If you've gone to larger tires, regearing helps restore towing performance. 4.88 gears are popular for 37" tires and maintain good towing capability.
Transmission Cooling
Heavy towing generates heat. Consider an auxiliary transmission cooler if you'll tow regularly with larger tires.
Brake Controller
Always use trailer brakes. The integrated controller works well, but aftermarket controllers offer more adjustment.
Weight Distribution Hitch
For trailers over 4,000 lbs, a weight distribution hitch significantly improves stability and handling.
What Can You Actually Tow?
Common trailer weights for reference:
- Teardrop camper: 1,500-3,000 lbs
- Small travel trailer: 3,000-4,500 lbs
- Mid-size travel trailer: 4,500-6,000 lbs
- Side-by-side on trailer: 2,500-3,500 lbs
- Toy hauler: 6,000-10,000 lbs
- Boat (typical): 2,000-5,000 lbs
The Bottom Line
A stock Gladiator is an excellent tow vehicle. A heavily modified one is still capable, but you need to be realistic about reduced capacity. If towing is a primary use, consider moderating your modifications or planning for reduced capability.
Our recommendation: If you regularly tow 5,000+ lbs, keep the lift under 2" and tires at 35" or smaller. Beyond that, you're significantly compromising the Gladiator's towing advantage.
