Question:
I have TDE 49936 3500lb axles on a car trailer. I’d like to find an axle flip kit. Also, I’d like to see if there are any axles that I could swap that are heavier duty that could hold more weight.

Hi Mike; since it is a 3,500 lb axle the diameter is likely 2-3/8" which means the # K71-384-00 you looked at is the correct kit. Occasionally they can have a 3" diameter so I recommend checking to be sure. If it is 3" you need the # K71-385-00 instead.
If you want to swap out the axle the next size up is a 5,200 lb. You would need to match your current hub face measurement. Keep in mind, adding a higher capacity axle will not increase the capacity of the trailer. Even if you swap out the axle, hubs, wheels, tires, and leaf springs the overall capacity remains the same.

Hey Mike, how did things go with checking the axle diameter on your trailer? Were you able to confirm if the 2-3/8 inch kit worked or if you needed the 3-inch version instead? Knowing what fit could help others with the same TDE 3500 lb setup.
