“Flipping the RV’s axles” is usually undertaken to gain some height to the unit and most units will benefit from 3-6” of extra clearance from doing so. Generally RV’ers that are travelling into the back-country, have lower sitting RV’s or a lifted tow vehicle that will benefit from an axle flip.
An axle flip can prevent lots of avoidable damage to holding tanks, gate valves, jacks, or anything else hanging low that could potentially be damaged by limited clearance.
Although it is called an “axle flip”, there is actually no flipping of the axles at all. This is a common misconception and can sometimes have do-it-yourself RV’ers caught in a dangerous situations where there is improper tire wear and impediment in braking.
Instead of flipping the axles, what an axle flip actually is, is removing the axles from their normal mounted position above the springs (overslung) to under the springs (underslung). A fairly simple process, however, knowledge is needed about metal integrity, the RV braking system and welding.
During an axle flip many parts may require replacing. The standard parts are spring saddles, u-bolts, nuts, shackle bolts and bushings (if worn).
Axle flips can only be completed on spring type axles. If your RV has torsion axles, you can install a lift kit similar to that of a regular truck.
Most RV service centers will have both options available and technicians that are proficient in completing the task.
