Description
Description
A workhorse trailer that’s the perfect size for many people. These plans are designed with Full Engineering for an excellent 4′ x 8′ – 3500# utility trailer with a torsion axle. An excellent choice for all sorts of yard and garden, home remodeling and other chores. Plus it’s not so big for storing.
These plans include a lot more than just the trailer. Our competitors sell plans for a specific trailer. Not us. These plans include lots of options so you can build the trailer to do the things you need a trailer for. We know one trailer does not meet all needs, so choose from options in the plans, or add your own.
This is a tough, 4′ x 8′ torsion axle trailer design, with full 3500# strength as a flat bed. While you can add sides (options are in the plans), they are not necessary for full strength. See more product detail by looking at the 4′ x 8′ – 3500# leaf spring suspension utility trailer. They are similar, with the same options, except the axle.
We have alternate sizes — like 4×8-2000# or 5×8-3500# — if that works better.
If you prefer a leaf spring suspension, we have plans for that too.

Plans are fully engineered and include easy to follow, illustrated instructions, with a parts list, and recommendations for materials and components.

We recommend looking through the options, then choose the ones that will make the trailer perfect for you. Use our ideas, or some of your own. While you may want a simple plain trailer, there are options too. A top, sides or tailgate. Maybe a ramp, a tongue mounted toolbox, tie-down bars, or something else.

Notes for Success
* Trailer load capacity depends on all the parts and materials, as well as the craftsmanship in building. All Mechanical Elements trailers are engineered to perform as stated when built as defined with proper care in construction – including parts, material, construction techniques, weld integrity, assembly methods, and finishing. Capacity for this trailer also requires proper choices for parts such as the hitch, axle(s), wheels, tires, safety chain, decking, bolts, pins, etc. Please make sure component load capacities match or exceed the trailer total capacity. Do not exceed manufacturers limits.
For trouble-free trailer life, think care and safety. Please select fastening methods to handle how and where the trailer will operate – including vibration, proper fastener types, bolt grades, torques, and nut types (like lock nuts). Then, be smart about loading the trailer, load distribution, tire pressure, tire condition and the mechanics of towing. We want you safe to enjoy your trailer for a long time ahead. Always use proper safety and securing equipment when loading and towing a trailer.
Thank You — The Mechanical Elements Team
