Replacing a trailer jack handle is a straightforward repair that takes 15 to 30 minutes and costs between $15 and $50 for the replacement part
A broken or bent trailer jack handle is one of the most common wear items on a trailer. The handle takes repeated stress every time you raise or lower the jack, and over years of use the metal fatigues, cracks, or bends beyond safe operation. Replacing it does not require special tools or welding — you unbolt the old handle, bolt on the new one, and you are done. The hardest part is usually finding the exact replacement part for your jack model.
The process differs slightly depending on whether your jack uses a bolt-on handle or a welded one. Most modern trailers use bolt-on handles, which are designed for replacement. If your handle is welded to the jack body, you will need to cut it off and either bolt on a new one or have a shop weld a replacement in place.
Key Takeaways
- Bolt-on handles unscrew with a wrench or socket and take 15 minutes to replace; welded handles require cutting and either bolting a new one or paying for welding.
- You need the jack model number or a photo of the handle to order the correct replacement, because handle sizes and bolt patterns vary widely.
- Most replacement handles cost $20 to $40 and are sold by trailer parts suppliers, RV retailers, and online marketplaces.
- A socket wrench or adjustable wrench is the only tool most people need; a reciprocating saw or angle grinder is required only if the handle is welded.
Identifying your jack type and handle style
The first step is determining whether your handle is bolted or welded. Look at the base of the handle where it connects to the jack body. If you see a bolt head or nut on the underside or inside of the connection, it is bolt-on. If the handle appears to be one solid piece of metal with no visible fastener, it is welded.
Write down your jack brand and model number. This information is usually stamped or printed on a plate attached to the jack body itself. Common brands include Fulton, Atwood, Lippert, Dexter, and Dutton-Lainson. The model number tells the parts supplier exactly which handle will fit your jack, because bolt patterns and handle lengths vary by manufacturer and jack capacity.
Take a photo of the jack from multiple angles, especially the handle connection point. If you cannot find the model number, this photo will help a parts supplier identify the correct replacement.
Removing a bolt-on handle
Bolt-on handles are held in place by one or two bolts, usually located at the base where the handle meets the jack body. The bolt may be on top, underneath, or on the side depending on the jack design.
Use an adjustable wrench, socket wrench, or box-end wrench to loosen and remove the bolt or bolts. You may need to hold the nut on the opposite side with a second wrench to prevent it from spinning. Once the bolt is out, slide the old handle away from the jack body. Clean any rust or debris from the bolt holes before installing the new handle.
Slide the new handle into place, align the bolt holes, and insert the bolt. Tighten firmly but do not over-tighten, which can strip the threads or crack the handle. The handle should not wiggle when you explore side pressure, but you should not need to use all your strength to tighten it.
Removing a welded handle
If your handle is welded, you will need to cut it off. A reciprocating saw with a metal-cutting blade works well and takes 5 to 10 minutes. An angle grinder is faster but requires more skill and safety precautions. Mark a cutting line about half an inch above the weld to leave enough material for bolting on a new handle.
After cutting, use a file or grinder to smooth the cut edge and remove any sharp burrs. Clean the area thoroughly to remove metal dust and debris.
Once the old handle is removed, you have two options: bolt on a new handle using the same method as above, or have a welding shop weld a new handle in place. Bolting is cheaper and does not require a shop visit. Welding creates a permanent connection but costs $50 to $150 depending on your location and the shop.
Finding and ordering the correct replacement handle
Contact the jack manufacturer directly with your model number, or call a trailer parts supplier and provide the brand and model. Suppliers like Tractor Supply, Camping World, and online retailers like Amazon and eBay stock common replacement handles. Specialty RV and trailer parts websites often have the widest selection.
Expect to pay $20 to $40 for the handle itself. Shipping may add another $5 to $15 depending on the supplier and your location. Some suppliers offer next-day or two-day shipping if you need the replacement urgently.
If you cannot find an exact match, a universal bolt-on handle may work if the bolt pattern and handle length are similar to your original. Measure your old handle from the connection point to the end, and verify the bolt hole spacing before ordering a universal replacement.
Tools and materials you will need
| Item | Purpose | Notes |
|---|---|---|
| Adjustable wrench or socket set | Remove and install bolts | Size depends on your jack; 7/16" or 1/2" are common |
| Replacement handle | New handle for your jack | Must match your jack brand and model |
| Reciprocating saw or angle grinder | Cut off welded handle | Only needed if handle is welded |
| File or grinder | Smooth cut edges | Only needed if handle is welded |
| Wire brush or cloth | Clean bolt holes and connection area | Removes rust and debris |
Testing the new handle before use
Before you load the trailer or rely on the jack, test the new handle under no load. Raise and lower the jack several times by hand, explore steady pressure. The handle should not wiggle, creak, or feel loose. If it does, stop and check that the bolt is tight.
If the handle still feels unstable after tightening, remove it and inspect the bolt holes for damage or stripping. If the holes are stripped, you may need to drill a new hole nearby or use a larger bolt with a washer to distribute pressure over a wider area.
Frequently Asked Questions
Can I use any bolt-on handle as a replacement?
No. Bolt patterns, handle length, and the diameter of the bolt holes vary by jack manufacturer and model. Using the wrong handle can result in a loose or unstable connection that fails under load. Always order a replacement designed for your specific jack brand and model.
What if I cannot find the model number on my jack?
Take clear photos of the jack from multiple angles, including the handle connection and any visible markings or plates. Call a trailer parts supplier with the photos and the brand name if you can see it. Many suppliers can identify the model visually and recommend the correct replacement handle.
Is it safe to weld a new handle on myself?
Welding a trailer jack handle requires skill and proper equipment. A poorly welded connection can fail under the stress of raising and lowering a loaded trailer, creating a safety hazard. If your handle is welded and you want to keep it that way, have a professional welding shop do the work. Bolting on a replacement is safer and does not require special skills.
How tight should the bolt be?
Tighten the bolt firmly so the handle does not wiggle when you explore side pressure, but do not use excessive force. Over-tightening can strip the threads, crack the handle, or damage the jack body. If you are unsure, tighten until snug and then test the handle by hand before using the jack under load.
Can I replace the handle while the trailer is hitched to my vehicle?
Yes, as long as the trailer is on level ground and the jack is not supporting any weight. Lower the jack completely so it is resting on the ground, not holding up the trailer tongue. This removes all pressure from the handle and makes the replacement safe and straightforward.
