You should have a "build sheet" in your owner's packet that lists everything in and on your RV. It will list the axles by model number and by serial number.

If by describing the "bowed" axle, you mean the "arch" from wheel to wheel, where the axle rises at the center, that is designed into the way the axle beam is constructed so when weight is applied, it flattens out and the wheels ride correctly. If there's some other "bow" in the axle, then it may be defective.

At any rate, your axles are listed on the build sheet. If you can't find it, Keystone has the original. You "should" be able to get a copy or at least the information you need by giving customer service a call during business hours.

Good luck.
