Since the GVWR of your 2002 Coachman Catalina 24 5th wheel is 11500lbs your trailer have the # 11 Torflex 4100-6000lb axles or # 12 5000-7200lb axles so I recommend double checking the information on your axle tag to confirm the model number of your axles.
If you have the # 11 axles you will need the Torflex Lift Kit - Tandem Axle - 2-7/8" Lift # K71-724-02, and if you have the # 12 axles you will need the # K71-725-02 instead as long as your axles do not have the 3" high lift brackets... view full answer...
