Car Trailer Plans

Fabplans specialise in DIY car trailer plans designed for builders who want strength, safety, and precision engineering all in one easy-to-follow package. Whether you’re hauling your classic car, race car, or everyday vehicle, our car trailer designs make it simple to build a reliable trailer that performs as it should.
Why Build Your Own Car Trailer?
Building your own car trailer gives you full control over the quality, strength and functionality of your setup. You can buy a basic tandem-axle car trailer off the shelf, but most mass-produced options are designed to meet minimum standards, not exceed them.
When you build your own trailer, you can:
- Customise the deck length and width to suit your vehicles.
- Select your preferred axle and suspension setup.
- Choose materials that balance weight and durability.
- Integrate extras like winches, tie-downs, toolboxes, and ramps.
With Fabplans, you get professionally engineered blueprints that guide you every step of the way—so you can confidently build a car trailer that’s safe, roadworthy, and tailored to your needs.
What Size Car Trailer Do You Need?
The best size for your trailer depends on what you plan to carry. If you’re hauling compact vehicles such as a Mini, Torana, or MX-5, a smaller single-axle design is ideal. For larger vehicles, 4WDs, or multiple loads, a tandem-axle trailer offers greater stability and load capacity.
When planning your build, consider:
- Overall deck size: Allow for extra space to make loading easier.
- ATM (Aggregate Trailer Mass): Choose a rating suited to your heaviest expected load.
- Storage: Make sure you have space to store your trailer when not in use.
Engineered for Safety & Performance
Every Fabplans car trailer design is FEA-tested, professionally engineered, and backed by years of hands-on fabrication experience. We focus on creating DIY-friendly plans that use standard steel sections, easily sourced components, and realistic fabrication methods.
Each plan includes:
- Comprehensive engineering drawings for every section
- Cut lists and part lists
- Information booklet to guide you through your build
- DXF files for sheet/plate parts
The result is a design that’s both accurate and achievable, even for builders working from a home workshop.
Versatile Car Trailer Options
Our car trailer range covers a variety of setups, including:
- Beavertail car trailers for general vehicle transport
- Airbag lowering car trailers for low-clearance cars and show vehicles
- Tilt-deck trailers for easy loading without ramps
Each design can be tailored to suit your vehicle type, towing capacity, and fabrication preferences. For example, if you’re moving high-value or low-slung cars, our airbag trailer plans allow you to drop the deck right to the ground which eliminates the steep loading angle and reduces the risk of underbody damage.
Customising Your Car Trailer
Once your base trailer is complete, the possibilities are endless. Many builders choose to add:
- Electric winches for easier loading those out of action vehicles
- Integrated ramps or tilt mechanisms
- Aluminium checker plate floors or sides
- Toolboxes and spare wheel mounts
- Hydraulic systems for advanced builds
Because all Fabplans designs are modular, it’s easy to adapt your trailer over time as your needs evolve.
