    Fits my 5x8 utility trailer perfectly

    This exactly fits my trailer and replaces the original Dexter axle that has many thousands of miles on it. I use this trailer daily all summer long and have for over 15 years. The original axle was bent and worn from bearings going out. Install was very easy after I got the old axle off. I had to but the spring bolts to get it off. I should have bought new spring bolts as well but was able to get some from the local hardware store. My only gripe is how much the shipping cost but I understand that it is an oversize and heavy item, so it is what it is.

    Great job

    Couldn’t be happier I got exactly what I ordered, I needed a custom axle the measurements were exactly how I ordered the axle and the price was very reasonably! For further trailer parts I will definitely consider Trailer parts first!
