If you're replacing a worn spindle or building a custom axle, this 4" drop spindle provides a secure mounting point for compatible hub and brake components. It also helps lower trailer ride height for compatible axle builds.
A bent or worn spindle can keep your hub from mounting properly, affecting how your trailer tracks down the road and how suspension components fit together. This 4" drop spindle replaces a damaged spindle or serves as the foundation for a custom axle, restoring a secure mounting point for compatible hub and brake components.
A 4" drop spindle lowers trailer ride height without changing the axle beam, making it a practical choice for custom builds or replacement projects where additional clearance or a lower deck height is needed. Weld-on installation provides a secure attachment to compatible trailer axles.

Hi everybody, Andy here with etrailer. Let's take a quick look at this Terran Industries spindle for your 3,500 pound trailer axle. Now this 4-inch drop spindle is made for your 3,500 pound trailer axle and it can be used either to replace a damaged spindle or as part of a custom axle build. But the main thing that sets this apart is that 4-inch drop. Instead of keeping the hub in line with the axle beam, the spindle positions it lower, which can help lower the trailer's ride height or deck height. And that can be useful on trailers where easier loading, lower center of gravity, or a specific custom axle setup is needed.
So again, this spindle is designed for a 3,500 pound axle and it has a 2-3/8-inch diameter. Matching the axle capacity and dimensions are important before picking this up. And you should not assume that every 3,500 pound trailer axle uses the same spindle setup. So checking the existing axle, spindle measurement and hub or bearing requirements is important. Now this is a weld on spindle.
It needs to be positioned and welded accurately so it stays square and concentric with your axle. If it's installed slightly out of alignment, that can lead to poor tracking, uneven tire wear, or other suspension issues. So for that reason, it is generally better suited for an experienced welder, axle shop or trailer fabricator. And if you need help finding one in your area on this product page underneath our photo section, we have a link that will take you to our installer locator. Click that link, answer the questions that it has for you, and that locator will find an installer in your area that etrailer has partnered with to get this installed for you.
But one of the biggest reasons that you might choose a replacement spindle like this is cost. If the axle itself is still in good condition, but the original spindle is bent, worn or damaged, replacing the spindle can potentially save you from replacing the entire axle. And it can also be useful if you're fabricating an axle and you're needing a 4-inch drop configuration. I think that's going to wrap up our look today. I hope that it was helpful for you.
Again, my name's Andy, thank you for joining me.
