Things to keep in mind when purchasing your 3.5K TK Trailer Axle

Whether you are repairing, upgrading or building a trailer, it is important to keep a few things in mind when purchasing your 3.5K TK Trailer Axle and what supplier you are getting from.

  1. First and foremost, you have to consider your urgency. How fast do you actually need this; it is important to know whether or not the company you choose to buy from has it in stock and if so, how long it will take to get it to you.
  2. Secondly, consider your usage and frequency. What am I going to be using it for, and how often. This will help determine whether you need the most costly and reliable brand, or if you can afford to get a more cost effective, but still high quality option.
  3. Above all, remember that your trailer axle is the foundation of your trailer and can mean the difference between a running business and trailer that is stuck on the side of the road.

In conclusion, time is money, especially if you are using your trailer for business, so when it comes to getting an axle, choosing the right supplier is extremely important.

Do’s & Don’ts when purchasing your 3.5K TK Trailer Axle

There are many do’s and don’ts when it comes to purchasing your trailer axle, but for simplicity, we will be outlining the top 3

  1. Make sure you get accurate and precise measurements on your axle. This is especially important if you are replacing an axle you currently have. Ordering the wrong axle will cost you time and money
  2. Do not underestimate what you are going to be using your trailer for. Always lean towards the higher capacity if you’re ever unsure. Bending an axle or having to upgrade your undercarriage will cost much more than doing it right the first time.
  3. If you are replacing your axle, check all of your suspension and other moving parts; also check other trailer parts that might need to be replaced. Often times, when one thing starts falling apart, the rest soon follows.
