Hitch Warehouse Tip

When replacing an axle, always double-check your hub face and spring center measurements - even a small difference can cause alignment issues or tire wear.

If you’re switching from overslung to underslung, expect the trailer to sit higher - this can be useful for clearance but may require adjusting your coupler height.

Before hitting the road, take a few minutes to manually adjust the electric brakes - it makes a big difference in stopping performance and longevity.
