Increasing the clearance of your trailer is essential for avoiding obstacles and ensuring a smoother ride on uneven terrain. By adjusting the height, you can enhance the trailer’s versatility and protect its undercarriage from damage.
What Is Trailer Clearance and Why Is It Important?
Trailer clearance refers to the distance between the ground and the lowest point of the trailer. Adequate clearance is crucial for navigating rough roads, steep inclines, and off-road conditions without damaging the trailer’s underside. Enhancing trailer clearance can improve safety and performance, especially for those frequently traveling on uneven surfaces.
How to Increase Trailer Clearance: Key Methods
Increasing trailer clearance can be achieved through various methods, each with its own benefits and considerations. Here are some common approaches:
1. Adjusting the Suspension
One of the most effective ways to increase trailer clearance is by modifying the suspension system. Consider the following options:
- Leaf Spring Adjustment: Re-arching or replacing leaf springs can raise the trailer’s height. This method is cost-effective and suitable for trailers with leaf spring suspensions.
- Torsion Axle Adjustment: If your trailer has a torsion axle, adjusting the ride height setting can increase clearance. This usually involves repositioning the trailing arm.
2. Installing Larger Tires
Larger tires can provide additional clearance by raising the trailer’s overall height. When selecting tires:
- Ensure Compatibility: Check that the new tires fit the existing wheel wells and do not interfere with the trailer’s frame or body.
- Consider Load Ratings: Choose tires with appropriate load ratings to maintain safety and performance.
3. Axle Flip or Over-Under Conversion
Flipping the axle or converting from an under-slung to an over-slung configuration can significantly increase clearance. This involves repositioning the axle to sit below the leaf springs rather than above them.
- Professional Installation Recommended: Due to the complexity and safety concerns, it’s advisable to have this modification done by a professional.
4. Adding Lift Kits
Lift kits are designed to raise the trailer’s height, similar to those used in off-road vehicles. They come in various forms, such as:
- Block Lift Kits: These kits add blocks between the axle and the trailer frame, providing a straightforward height increase.
- Spacer Kits: Suitable for trailers with torsion axles, these kits add spacers to increase clearance.
Pros and Cons of Increasing Trailer Clearance
| Method | Pros | Cons |
|---|---|---|
| Suspension Adjustment | Improved ride quality, affordable | May require professional help |
| Larger Tires | Easy installation, enhanced traction | Potential for increased wear on parts |
| Axle Flip | Significant clearance gain | Complex, may affect towing dynamics |
| Lift Kits | Customizable height options | Can be expensive, affects aerodynamics |
Practical Considerations
When increasing trailer clearance, consider the following:
- Balance and Stability: Raising the trailer’s height may affect its balance and towing stability. Ensure weight is distributed evenly.
- Legal and Safety Regulations: Check local laws regarding trailer height and modifications to ensure compliance.
- Impact on Fuel Efficiency: Increased height can lead to higher wind resistance, potentially affecting fuel efficiency.
People Also Ask
How Do I Know If My Trailer Needs More Clearance?
If you frequently experience scraping or bottoming out on uneven roads, or if the trailer’s undercarriage shows signs of damage, it may be time to increase clearance. Also, consider clearance if you plan on off-road travel.
Can I Increase Trailer Clearance Myself?
While some methods, like installing larger tires, can be done by experienced DIYers, others, like axle flips or suspension adjustments, are best left to professionals due to their complexity and safety implications.
What Are the Risks of Increasing Trailer Clearance?
Raising a trailer too high can lead to stability issues, increased wind resistance, and potential legal compliance issues. Always consult with a professional to ensure modifications are safe and effective.
How Much Does It Cost to Increase Trailer Clearance?
The cost varies depending on the method chosen. Simple adjustments like tire changes might cost a few hundred dollars, while more complex modifications like lift kits or axle flips can run into the thousands.
Will Increasing Trailer Clearance Affect Towing?
Yes, it can affect towing dynamics by altering the trailer’s center of gravity and aerodynamics. It’s crucial to ensure the tow vehicle and trailer are compatible after modifications.
Conclusion
Increasing trailer clearance can significantly enhance your trailer’s functionality and safety, especially when traveling off-road or on uneven surfaces. By choosing the right method and considering professional assistance, you can ensure a successful modification.
