This Hot-Dipped Galvanized Torsion Axle Assembly comes completely assembled with 5 lug Galvanized Hubs, ready to be installed to your trailer's 80 inch wide I Beam Frame.  This V-Bend Axle features Posi-Lube Spindles which makes Bearing Maintenance a Breeze.  Looking for a new Boat Trailer Torsion Axle has never been easier, we've included all the measurements below, but the most important measurement is your Galvanized or Aluminum I-Beam Frame width, and the Trailer Axle Hub Face Measurement.

Torsion Bar Axles eliminate the need for Leaf Springs on your trailer.  A new Galvanized Torsion Axle is a great upgrade to any boat trailer or utility trailer.  Torsion Arm Axles feature rubber chords inside the axle which gives the trailer the suspension it needs.  These rubber chords do not rust as leaf springs do, so they last much longer in marine environments.  Additionally, this is the only Boat Trailer Torsion Axle on the market with a fully Hot-Dipped Galvanized Torsion Arm, making it great for freshwater boat trailers and the best Galvanized Axle for saltwater trailers.  This torsion axle also has a drain hole at the bottom of the V-Bend to purge any water that gets into the tubing, further helping to prevent rust.

This Torsion Axle ships directly to your door with the Hot-Dipped Galvanized 5 lug Hubs and 1.98 inch Greaseable Dust Caps already installed.  Just add your Tires & Wheels along with some Lug Nuts and your trailer will be road-ready again in no time. This particular torsion axle is designed for Fresh or  Saltwater, and is made to fit I-Beam Trailer Frames that are 80 inches wide.  Please Double Check all the Measurements Below to ensure this Torsion Axle is a good fit for your trailer.
