What are the Differenced Between EZ4 and EZ5 Roadmaster Base Plate Kits for 2016 Chevy Spark


Am looking at the base plate RM-523185-5 and am not clear what the real differences are between it and RM-523185-4. Can you please clarify? Thanks

The difference between the EZ4 Base Plate kit part # RM-523185-4 and the EZ5 kit # RM-523185-5 is that the EZ4 uses twist-lock drawbars while the EZ5 uses drawbars held in place by pins and doesn't require the use of a crossbar.

I would go with the EZ5 if it were me since not having to use the crossbar is just one less thing to worry about.

In addition to the base plates, you will also need a compatible tow bar, safety cables, lighting, and supplemental braking to flat tow your vehicle. The most popular compatible tow bar is the Falcon 2, # RM-520. For safety cables you can use # RM-643. The coiled design helps keep the cables off of the ground.

For lighting you can use the diode kit, # RM-15267, and not have to worry about cutting into the taillight housing. This will splice into your taillight wiring to allow your tow vehicle to control the taillight assemblies of the towed vehicle. This comes with a round 6-way connector that you will install on the front of your towed vehicle and enough coiled wire to go from there to the RV.

And finally, most states now require supplemental braking in the vehicle being flat towed. The easiest system to set up and use is the Blue Ox Patriot # BRK2019, that applies the vehicle brakes in proportion to how much the tow vehicle is braking. This is the safest way to stop and it reduces wear and tear on both vehicles.

Most likely you will also need a high low adapter so that the tow bar will be level when you are flat towing. I attached a link to a page that has all of the ones we carry.

I have included a couple of helpful links to our articles on flat towing for you. Be sure to consult the vehicle owners manual for more specific information on flat towing your vehicle.
