WARNING: Failure to use proper equipment and driving technique can result in loss of vehicle control when towing. Improper towing can result in serious injury. Follow the guidelines below carefully and consult your authorized Sprinter dealer if needed.
Vehicle Weight Ratings
| Model | GVWR (lbs) | GAWR Front (lbs) | GAWR Rear (lbs) | Max GTW (lbs) | Max Tongue (lbs) |
|---|---|---|---|---|---|
| 2500 C/HC/SHC | 8,550 | 3,860 | 5,360 | 5,000 | 500 |
| 3500 C/HC/SHC | 9,990 | 3,860 | 7,060 | 5,000 | 500 |
GVWR = Gross Vehicle Weight Rating. GAWR = Gross Axle Weight Rating. GTW = Gross Trailer Weight.
Towing-Related Torque Specifications
Always use a calibrated torque wrench for safety-critical towing fasteners.
| Fastener | Torque (ft·lbs) | Notes |
|---|---|---|
| Hitch receiver mounting bolts | 85 ft·lbs | Use Sprinter-approved receiver only. Check torque before each towing season. |
| Hitch ball nut | 75 ft·lbs | Torque depends on ball shank diameter; verify with ball manufacturer. |
| Wheel lug nuts (tow vehicle) | 133 ft·lbs | Re-torque after first 50–100 miles of towing. See tire pressures guide. |
Pre-tow check: Inspect all hitch fasteners for tightness before every trip. Vibration from road travel can loosen bolts over time. Replace any fasteners showing signs of corrosion or thread damage.
Permissible Roof Load
Low Roof
Maximum roof load: 660 lbs (300 kg), including roof rack and all cargo.
High Roof
Maximum roof load: 330 lbs (150 kg), including roof rack and all cargo.
Required Equipment
Trailer Hitch
- Only use a Sprinter-approved hitch receiver
- Do not use clamp-type or bumper-type hitches
- Remove the ball adaptor when not in use
- Inspect the hitch for cracks or corrosion before each tow
Electrical Connections
- Use only the correct Sprinter receiver wiring kit
- Incorrect installation can damage the vehicle's electrical system
- Have harnesses connected by an authorized dealer
- Test all trailer lights before every trip
Safety Chains & Brakes
- Use crisscrossed safety chains attached to the hitch receiver
- Never attach chains to bumper or axle
- Leave enough slack for turning
- A break-away switch is required in most jurisdictions
Important: Never connect a trailer brake system directly to the vehicle's hydraulic brakes. Use the provided wiring harness for brake controller hookup. Consider using a trailer sway control system for added safety.
Attaching a Trailer - Pre-Departure Checklist
Before Hitching
- Verify trailer dimensions comply with local regulations
- Weigh the loaded vehicle-trailer combination on a commercial scale
- Check front/rear GAWR, GTW, and tongue weight; do not exceed any rating
- Ensure ball size matches the trailer coupler
After Hitching
- Coupler fully seated on ball, locking mechanism engaged
- Safety chains crisscrossed and attached to receiver
- Electrical connector plugged in - test all lights
- Break-away cable attached (if equipped)
- Trailer brakes tested - pull forward slowly and apply
Towing Best Practices
Driving
- Start slowly and test brakes before reaching traffic speed
- Maintain extra following distance and allow for longer stopping
- Avoid sudden maneuvers, as towing changes handling and stability
- Apply brakes gently to let the trailer brakes activate first
- Adjust mirrors for a clear view beyond the trailer width
- Secure all items in the trailer to prevent load shifts
Hills & Engine Management
- On inclines, shift to a lower gear to reduce engine load
- Use engine braking on long descents; avoid riding the brakes
- If coolant temperature nears the red zone, turn off A/C and increase fan speed
- Pull over safely if overheating persists and let the engine idle to cool
- Allow extra passing distance; the combination is longer than the vehicle alone
Tip: Practice turning, stopping, and backing up in an empty parking lot before driving in traffic. Backing up with a trailer requires steering in the opposite direction, so go slow and use a spotter.
Parking with a Trailer
1
Keep your right foot on the brake pedal. Shift gear selector to N (neutral).
2
Have a second person place wheel chocks on the downhill side of the trailer wheels.
3
Release the brake pedal slowly. Let the vehicle and trailer roll gently into the chocks.
4
Firmly engage the parking brake.
5
Move gear selector to P (park). On inclines, turn front wheels toward the curb.
Frequently Asked Questions
The Sprinter T1N can tow up to 5,000 lbs (2,268 kg) gross trailer weight with a Sprinter-approved hitch. Maximum tongue weight is 500 lbs (227 kg). GVWR is 8,550 lbs (3,878 kg) for the 2500 and 9,990 lbs (4,531 kg) for the 3500.
Only use a Sprinter-approved trailer hitch receiver. Do not use clamp-type or bumper-type hitches as they can damage the vehicle. Remove the hitch ball adaptor when not in use to prevent damage from road debris. Inspect for cracks or corrosion before each tow.
Most states and all Canadian provinces require trailers above certain weights to have a separate brake system with a break-away switch. Never connect a trailer brake system directly to the vehicle's hydraulic brakes. Use the provided wiring harness for a brake controller hookup.
Low roof: 660 lbs (300 kg). High roof: 330 lbs (150 kg). This includes the weight of the roof rack itself plus any cargo mounted on it.
Keep foot on brake, shift to neutral, have someone place wheel chocks on the downhill side, slowly release brakes to roll into chocks, engage parking brake, then shift to park. On inclines, turn front wheels toward the curb.
