Our Newest Utility Trailer Blueprints – for Torsion Axles

Again – You Asked, and We’re Delivering!  New sets of DIY utility trailer blueprints are now in the Mechanical Elements plans store.  Yes, new plans engineered for torsion axles.  The designs provide a great ride with great strength on rubber.  < Read More >

Torsion axles apply unique loads to the trailer frame compared to leaf springs.  Ignoring this can lead to over-stressed components.  A robust design handles the loads, so we’ve done just that.  These new trailer blueprints with illustrated instructions are ready for download – including utility trailers — a 4’x6′-2000#, and a 4’x8′-2000# — then an all new 4’x6.5′-2500# Off Road Trailer with even more ground clearance!

Some sites brag about “Engineer Approved” plans.  We’ll do one better . . . these plans are created by the Engineer with full analysis.  Get started with this guide to choosing your DIY Trailer Plans.

Blueprints for your next project — A fantastic Trailer, a Gantry Crane or a Storage project.
