Torsion Axle Conversion Plans – 3500 lbs.
Select Your Size

Description

Change the trailer from Leaf Springs, to a Torsion Axle Trailer.  These Conversion Plans show you how.

• This design fits our Single Axle, 4′, 5′, 6′ and 6’10” Width trailers, at 3500 lbs.  Select your width.
• They also fit other single axle trailers by modifying the axle width dimension in the drawings.
• We also offer TA Conversion Plans for our 6000 lb. and 7000 lb. Single Axle Trailers.

Change to a Torsion Axle Trailer.  Build with confidence, because these Conversion Plans have Full Engineering to mitigate added stress from a torsion axle.  No need to guess, because we did the engineering for you – including the torsion axle specification.

A Torsion Axle is good for ride quality, and simplicity.  A teardrop camper, a show bike trailer, and many more will benefit from the softer ride of a torsion axle trailer.  You can set the neutral angle down for more ground clearance, OR neutral angle up for a lower trailer deck.  And, torsion axles are available in galvanized versions for wet areas.

Now you can convert to a Torsion Axle easily, and make the Torsion Axle Trailer you want.

Change your axle and know the result will be strong.  For engineering information, please see the Trailer Axle Comparison article.  Leaf Springs and Torsions are different, so the mounting design must change a little for each axle type.  Read more about converting axles.

Conversion Plans fit – and go with – Mechanical Elements, 3500 lb., Single Axle Trailer Plans.

Torsion Axle Trailer Conversion Plans

• Plans show how to convert from a standard Leaf Spring axle to a Torsion Axle.
• Includes all the changes in parts and materials needed for the conversion.
• These plans show only the changes, so the regular trailer plans are also required.
• Single, Torsion Axle design for 3500 lbs axle capacity.
• A torsion axle gives more options for deck height (for more axle ground clearance or for a lower deck).
• Weight varies with axle options.  The conversion does not significantly change the total trailer weight.
• This conversion works with all the normal trailer plans options EXCEPT storing the ramp under the trailer bed.  All other options work.
• Torsion Axle ordering information is included.  All the details needed.
• Plans include complete Drawings and illustrated Instructions — all the info needed to make the conversion.

More About Torsion Axle Trailer Design

These Conversion Plans go hand in hand with the main trailer plans.  We could create a bunch of duplicate plans – Torsion Axle Trailer plans – but giving a long list seems awkward for you.  These conversion plans solve the problem by allowing you to choose the trailer you need, then make the conversion you want.

We recommend looking through the axle conversion plans along with the trailer plans to see the material changes.  It is just a few things, and the obvious axle change.  These conversion plans show the differences, so you can confidently make the axle change knowing the engineering is all done for you.

All of the options shown in the main trailer plans also work with this conversion,  EXCEPT the option for a ramp that slides in, and stores under the trailer.  All other options, like sides or tailgate, a tongue mounted toolbox, tie-down bars, and more will work fine with the change to a torsion axle.

Use these plans to make the torsion axle trailer, then customize your new trailer and make it perfect for you.

Single Axle – 3500# – Torsion Conversion

• The Axle conversion does not change the size of the trailer.  Choose your trailer, then choose the matching conversions plans width to make the axle conversion.
• Overall trailer length does not change.  Overall width can be slightly different depending on tires and other choices.
• Trailer deck height depends on your choice of the Torsion Axle neutral angle.  Can be higher or lower than the conventional leaf spring suspension design.
• Max capacity (for the trailer and for the conversion) is 3500#, * which includes the trailer weight.
• True Torsion Axle Utility Trailer Design – Engineered for long life – even with full loading.
• While the plans do have the build steps, there is more info to help in the trailer and construction tips here on the website.
