We Offer All Our Galvanized Dexter Axles with Hot-Dipped Galvanized Adjustable Spring Seats included with your Axle Purchase. This means no drilling required! No Holes in your Axle! These Proprietary Galvanized Spring Seats make Installing your new Axle easy with common tools in your drive way. This adds huge value to your axle purchase from us, a hassle free, easy to install galvanized trailer axle.
This galvanized boat trailer axle is manufactured by Dexter Axle and has a 3500 lb. weight capacity. Dexter Axle galvanized boat trailer axles are Hot-Dipped Galvanized for optimal corrosion resistance and superior protection from salt water. Dexter Axle is a leader in axle manufacturing and features AMERICAN MADE PRODUCTS.These axles are made of 2 inch x 2 inch x 1/4 inch thick square tubing.
The tapered spindle design on the 3500lb axle accommodates the following bearing and seal sizes:

-Inner Bearing - 68149 or 1 3/8 inch inner diameter

-Outer Bearing - 44649 or 1 1/16 inch inner diameter
-Grease seal - 1.719 inches inner diameter
The spindle features a Stainless Steel Wear Sleeve to allow for long term protection for your seal surface. This ensures your seal surface won't corrode away, meaning it will not pit or rust which would normally lead to letting water into your hub.Dexter Axle spindles also feature an E-Z Lube system, which allows easy greasing and regular maintenance of bearings. The grease travels through the center of the spindle and pushes out the old grease forward towards the front of the hub and out your dust cap, therefore replacing the old grease with new fresh grease. A castle nut and spindle washer are included on each spindle.


Our MADE IN THE USA , Proprietary and Patent Pending Adjustable Spring Seats allow for adjustment to your specific measurements. These Hot-Dipped Galvanized Adjustable Spring Seats mean your axle will last longer, with no holes for saltwater and corrosion to hide. These Galvanized Adjustable Spring seats are included free of charge with the purchase of your axle.

Galvanized Axle Measurements:
This is a Straight axle with brake flange (meaning you can attach brakes to this axle).
  • Hub Face: 86.5 inches
  • Overall Length (tip to tip): 91.5 inches
  • Spring Seat Measurement: Will safety accommodate 68.5 inches to 74 inches
Hub Face (Axle Track) refers to measuring from the OUTSIDE FACE of one hub to the OUTSIDE FACE of the opposing hub ACROSS the axle. Refer to axle measuring video for assistance.
Spring Seat Measurement refers to the measuring of your leaf springs from the center of one spring, across the axle to the center of the opposing spring. Getting assistance with this measurement from a friend is recommended. Refer to axle measuring video for assistance.

The Spring Seat Measurement is very important to ensure the safe and proper installation of this axle. If your Spring Seat measurement does not fall into the specified range, we cannot guarantee the successful installation or performance of your axle. Using a spring seat measurement that is too narrow will likely lead to your axle bending. Using a spring seat measurement that is too wide will lead to your tires rubbing on your trailer frame and/or leaf springs. Please verify that your Spring Seat Measurement falls into the range specified to avoid any problems.
