Raising your popup camper’s frame helps provide more ground clearance. You might not think this is needed for your camper, but simply navigating campground roads can sometimes cause your camper’s bumper to touch. This is because your popup acts a bit like a see saw on it’s axle. Raising the frame gives your bumper and even the front of the trailer more clearance.
The basic process for doing this is to flip the springs to rest on top of instead of underneath the axle. Many people inaccurately refer to this as “axle flipping,” but you don’t actually want to flip the axle, as it is cambered for a certain position. I highly recommend letting a qualified camper dealer or trailer repair shop do this work for you.
The amount of height gained will vary depending on your specific frame, axle, and spring setup. As you can see above, mine went up about 5″ to a new frame clearance of about 21″. Note that the steps, stabilizer jacks, and other items hang down lower than the frame.
Speaking of steps, you’ll likely want to either convert to a two-step system or bring along a step stool, as the raised height is a little too much of a jump for the stock step alone.
Some people will also install larger wheels and tires to give the axle more ground clearance.
Before raising my frame, I found that going over fairly small bumps would cause my camper to bounce so much that it rubbed the tire against the wheel well. Mine started to wear a hole in the wheel well, which would have let water inside the camper. Because of this, I’ve left my wheels at the stock 13″ and have not increased my tire size.
You might also want to consider replacing your stabilizer jacks, which might not easily make the extra 4 to 5 inches now that your frame is raised. I left mine stock and simply bring along some wood blocks, which I keep inside a tool box mounted to my trailer tongue.
