Choosing the Right Custom Axle Manufacturer
Finding the best manufacturer to procure a custom-built trailer axle is imperative to getting the right product.
1. Assess Needs and Priorities
Each custom axle manufacturer may have a unique approach to creating its product, and it’s critical to understand what best aligns with the company’s expectations. Companies must decide whether strict adherence to exact specifications is more critical or whether some involvement in axle construction is necessary.
2. Discuss the Engineering Process
Manufacturers should be able to elaborate about their engineering process to narrow down which would best meet the requirements at hand. Some will be able to procure a fully bespoke design from scratch that meets the exact specifications. Meanwhile, others can only reconfigure a standard axle.
3. Consider Long-Term Support
Many companies prioritize getting a custom-built trailer axle but may overlook potential problems down the road. The ideal prospects offer post-purchase support and replacement parts in case of issues. Warranties are also ideal.
4. Seek Quotes and Samples
Practicality should be front and center, especially when narrowing down options. An axle sample and a quote from each company can be compared for quality. Always take pricing and ROI into account.
Finalizing Specifications
The correct specifications are imperative to getting a custom-built trailer axle that fits properly. Consider collecting the following information before contacting a supplier.
1. Get the Essential Measurements
The relevant dimensions of the current or desired frame should be provided right away. The length can be measured by checking the distance from one end of the spindle to the other. Check other spots, like the distance between the sides of the flat mounting surface and the width of the trailer chassis. The distance between the leaf spring centers is also needed for nontorsion axles.
2. Choose an Axle Type
Trailers’ axles can come in all kinds of forms. The straight or leaf spring axle type is a standard and durable option that many companies will likely offer. If stability is a priority, drop axles are preferred because they offset the spindles and feature a downward bend. Torsion axles can lead to a smoother and quieter motion.
3. Gather the Technical Specifications
The custom-built trailer axle will be more accurate if the technical specifications are provided beforehand. For instance, indicate the maximum weight the axle can safely carry. It is also critical to share the number of lugs and the bolt circle diameter so the axle is compatible with the hub bolt.
Get the Exact Trailer Axles Needed For the Job
Custom-built trailer axles are vital for maintaining safety and efficiency. However, industry professionals must be critical when choosing a company to work with. Getting a reliable manufacturer to build according to the given specifications can improve trailer performance in the long run.
