Storing your trailer on jack stands is generally recommended for long-term storage to prevent tire deformation and potential damage to the axle and suspension. By lifting the weight off the tires, you’ll extend their lifespan and ensure your trailer is ready to roll when you need it.
The Case for Jack Stands: Protecting Your Investment
Leaving a trailer sitting on its tires for extended periods, especially in varying temperatures, can lead to flat spotting. This occurs when the tire’s sidewall takes a set in the position it’s held for a prolonged time, resulting in vibrations and an uncomfortable ride when you next use the trailer. Beyond tire concerns, continuous weight on the suspension can also contribute to its degradation over time. Jack stands offer a simple yet effective solution to these problems.
Benefits of Using Jack Stands
- Prevents Tire Flat Spotting: Lifting the tires eliminates the pressure that causes flat spots to develop. This is particularly important for trailers with radial tires.
- Extends Tire Lifespan: Reducing stress on the tires prevents premature wear and cracking, potentially saving you money on replacements.
- Protects the Suspension: By distributing the weight, jack stands reduce strain on the axle, springs, and other suspension components, preserving their integrity.
- Reduces Risk of Corrosion: Lifting the trailer slightly off the ground minimizes contact with moisture and road salts, reducing the risk of rust and corrosion, especially on the underside components.
- Deterrance of Theft: Although not a primary security measure, jack stands make it more difficult to quickly move a trailer, acting as a minor deterrent to theft.
Potential Drawbacks and Considerations
While the benefits are substantial, it’s essential to consider a few potential drawbacks:
- Initial Investment: You’ll need to purchase a set of appropriately rated jack stands.
- Setup Time: Placing the jack stands requires a bit of effort and careful positioning.
- Storage Space: You’ll need a place to store the jack stands when not in use.
- Safety Precautions: Improperly placed jack stands can be dangerous. Always use them on a level surface and ensure they are securely positioned.
- Compatibility: Some trailers, particularly those with specific suspension designs, may require specialized jack stands or lifting techniques.
Choosing the Right Jack Stands
Selecting the appropriate jack stands is crucial for safety and effectiveness. Consider the following factors:
- Weight Capacity: Determine the gross vehicle weight rating (GVWR) of your trailer and choose jack stands with a combined weight capacity that exceeds this figure. It’s always better to err on the side of caution.
- Height: Ensure the jack stands are tall enough to lift the tires completely off the ground while still providing ample stability.
- Type: Various types of jack stands are available, including pin-type, ratchet-type, and screw-type. Choose a type that you are comfortable and confident using. Ratchet-type are generally considered easier to adjust.
- Stability: Look for jack stands with a wide base for increased stability, especially when used on uneven surfaces.
- Construction Material: High-quality steel jack stands are generally more durable and reliable than those made from cheaper materials.
Proper Placement and Safety
Safety is paramount when using jack stands. Follow these guidelines:
- Level Surface: Always place jack stands on a level and stable surface.
- Secure Placement: Ensure the jack stands are securely positioned under the trailer frame, near the axles, or at designated lifting points specified by the trailer manufacturer. Never place jack stands under the axle itself unless specifically instructed to do so by the manufacturer.
- Chock the Wheels: Before lifting the trailer, chock the wheels that remain on the ground to prevent movement.
- Lower Slowly: Lower the trailer onto the jack stands slowly and carefully, ensuring they are properly supporting the weight.
- Regular Inspection: Inspect the jack stands regularly for signs of damage or wear.
- Never Exceed Weight Capacity: Adhering to the weight capacity is crucial. Overloading can lead to jack stand failure and serious injury.
- Use as a Pair: Always use jack stands in pairs for even weight distribution and stability.
Alternatives to Jack Stands
While jack stands are the most common and often recommended solution, there are alternatives to consider:
- Tire Covers: Tire covers can help protect tires from UV rays, which can cause cracking and dry rot. While they don’t prevent flat spotting, they can extend tire lifespan.
- Regular Rotation: Periodically moving the trailer a short distance can help prevent flat spotting by shifting the contact point on the tires.
- Inflate to Maximum Pressure: Inflating tires to their maximum recommended pressure can reduce the risk of flat spotting, but be sure not to exceed the manufacturer’s recommended limit.
- Tire Cradles: These devices cradle the tires and help distribute weight more evenly, reducing the risk of flat spotting.
Frequently Asked Questions (FAQs)
Here are 12 frequently asked questions addressing common concerns and offering further clarification:
1. How long can I store a trailer on jack stands?
There is no set time limit. Jack stands are designed for long-term storage, so you can leave your trailer on them for months or even years. The key is to ensure the jack stands are properly rated and positioned, and to inspect them periodically.
2. Can I use concrete blocks instead of jack stands?
Never use concrete blocks instead of jack stands. Concrete blocks are not designed to support heavy loads and can crumble or collapse unexpectedly, posing a significant safety risk. Only use jack stands specifically designed for this purpose.
3. Where exactly should I place the jack stands?
Refer to your trailer’s owner’s manual for specific lifting points. If the manual is unavailable, the frame of the trailer, near the axles, is generally a safe place. Avoid placing jack stands directly under axles unless specifically instructed by the manufacturer. Ensure the stands are placed on a solid, structural component.
4. Do I need to remove the wheels when using jack stands?
Removing the wheels is not necessary, but it can further reduce stress on the tires and bearings. If you choose to remove the wheels, store them in a cool, dry place away from direct sunlight.
5. Will using jack stands void my trailer warranty?
Using jack stands correctly should not void your trailer warranty. However, it’s always best to consult your warranty documentation and contact the manufacturer if you have any concerns. Improper use, leading to damage, could void the warranty.
6. What is the best type of jack stand for a heavy trailer?
For heavy trailers, choose heavy-duty steel jack stands with a high weight capacity (exceeding the GVWR of your trailer). Ratchet-type stands are generally easier to adjust and offer more precise height control.
7. Should I cover the trailer while it’s on jack stands?
Covering the trailer is a good idea to protect it from the elements, such as sun, rain, and snow. Use a breathable trailer cover that allows for air circulation to prevent moisture buildup.
8. How often should I inspect the trailer while it’s stored on jack stands?
Inspect the trailer and jack stands at least every few months. Check for signs of rust, damage, or instability. Also, ensure the tires are still properly inflated (if they are still on) and the jack stands are still securely positioned.
9. Can I use a floor jack to lift the trailer onto the jack stands?
Yes, a floor jack is an effective way to lift the trailer. Ensure the floor jack is also rated for the weight of the trailer. Always use jack stands to support the weight; never work under a trailer supported only by a floor jack.
10. What if I don’t have a completely level surface for the jack stands?
If you don’t have a perfectly level surface, use wooden blocks or leveling pads under the jack stands to create a stable and level base. Be sure to use strong and durable materials.
11. Is it necessary to lubricate the jack stands?
Lubricating the moving parts of the jack stands, such as the threaded rods or ratcheting mechanisms, can help prevent rust and ensure smooth operation. Use a light lubricant, such as WD-40 or a similar product.
12. Will using jack stands prevent tire dry rot?
While jack stands primarily address flat spotting, they can also indirectly help prevent dry rot by reducing stress on the tires. Combined with tire covers that block UV rays, jack stands contribute to overall tire preservation during long-term storage.
By taking the proper precautions and investing in quality jack stands, you can confidently store your trailer and ensure it’s ready for your next adventure.
