Best Price Guarantee

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 Features: 

Galvanized Axle Measurements:
This is a Straight axle with brake flange (meaning you can attach brakes to this axle).
  • Hub Face: 88 inches
  • Overall Length (tip to tip): 93 inches
  • Spring Seat Measurement: Will safety accommodate 70 inches to 75.5 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.

Trailer Axle Project Check List:

  Leaf Spring U-Bolt Kits – These typically rust at the same rate as the axle, requiring cutting or breaking during removal.  These kits will re-mount your new axle to your trailers leaf springs.  

   Trailer Leaf Springs  – Replacing rusted or broken leaf springs is crucial to prevent pre mature failure and damage to your suspension system and trailer tires.

   Leaf Spring Mounting Bolts – These Bolts secure your trailers leaf springs to your frame mounted Leaf spring hangers. They are commonly rusted just as much as the Leaf spring U Bolts, requiring replacement.

   Trailer Leaf Spring Shackles – These shackles are used with Double Eye Leaf Springs to provide the needed suspension for your trailer, held together by the above Leaf Spring Mounting Bolts.

  Galvanized Trailer Hubs - Including wheel bearings and grease seal, we have these hubs in 4 Lug and 5 Lug including the 1 1/16" Wheel Bearings for your Axle Kit.
   Trailer Dust Caps - New Dust Caps or Bearing Buddies provide the needed protection and greasing capabilities to protect your trailers axle and wheel bearings. 
   Trailer Lug Nuts - If your Lug Nuts are badly rusted, we have Stainless Steel Lug Nuts available to prevent that issue permanently, and also protect your Hub Studs.

I am very impressed with the grease zerk in which goes through axle and pushes the old grease out of the bearings along with the quality of the axle and free shipping, thank you and will continue to do business with you and recommend your business to others. Doug

Dexter makes a great axle, this was no different. I bought the entire set up. Springs, shackles, axle, hubs, all went together flawless. Loved the included spring plate, as opposed to drilling a hole in the axle. Shipping very reasonable, would not hesitate to buy again.

Happy With My Axle
I have a very positive experience with Sturdy Built. The support staff if very responsive and gives excellent descriptions. The Dexter axle arrived in 5 days and was delivered in good conditons. I like the "U" spring indexing pieces as they eliminate the need for holes to be drilled in the axle. Also like the stainless sleeve runners for the shaft seals to ride against. Very Positive experinece.

Perfect fit
Couldn't ask for a better fit or ease of insulation. It replaced a 30 year old axle beam, old hubs fit, couldn't ask for better. Just make sure spring centers and all measurements are the same

These axles were a great choice and the quality was excellent.The greasing design is first class. The axles arrived in perfect condition due to the proper packaging by the shipping department. I only had (1) minor complaint. The hub bearing would slide onto (1) end of (1) axle. I had to lightly file a chamfer then the bearing went right on.
