Question:

I want a hitch for my 2013 Acura RDX with a Max Towing rating of 1500 lb. You offer both a Class 2 and a Class 3 Hitch. The Class 2 1.25inch ball rated for 3,500 lb, and a Class 3 2inch ball rated for 4,000 pounds. Both are overkill for my towing limit, but why is the Class 2 hitch more expensive than the Class 3?

Hey Jim, it doesn't really make a whole lot of sense that the Class III 2 inch hitch part # C13130 that you referenced costs less than the Class II part # C12083 but to me that makes going with the Class III hitch that much more of a no-brainer as it has better towing capacities, is the more popular hitch size for accessories like bike racks, and it costs less. Are you planning on doing some towing?

If so, you'll also need trailer wiring like the part # 56008 which is custom fit for your vehicle.

I took care of my immediate need, and the motorcycle I needed to haul is already been done. But the point is, if you install a 4,000lb rated hitch on a truck that's only rated to pull 1500... seems to me you're asking for trouble.

@JimP you would just need to stay under the capacity of the lowest rated component in your setup and you'd be fine. Our hitches are generally overbuilt but it doesn't' give the vehicle any additional capacity as nice as that would be.
