  • How to Flat Tow a Second Generation Jeep Liberty 2008-2011
    In order to flat-tow a second generation (2008-2011) Jeep Liberty with all four wheels on the ground you will need a base plate kit, tow bar, flat-tow wiring harness, safety cables, supplemental braking system, and possibly a high-low adapter. I have attached my recommendations for each of these parts below. For a base plate kit I recommend the Roadmaster Base Plate Kit part # 521434-1 if you have a have rock guard or skid plate excluding Renegade, part # 521433-1 if you do NOT have a...

  • Roadmaster Base Plates for a Sterling Tow Bar and a 2011 Jeep Liberty
    The first thing you are going to want to do is consult the owners manual of your 2011 Jeep Liberty to determine if it can be flat towed or if anything additional is needed to tow the vehicle. From the research I did, all wheel drive models with automatic transmissions and models with 2 wheel drive and a 6 or 5 speed can only be towed on a trailer. Two wheel drive models with automatic transmission will require a transmission lube pump. And 4 wheel drive models with automatic transmission...

  • Will the Roadmaster EZ Base Plate Kit Work W/ the Roadmaster Explorer Tow Bar
    Tim, it looks like the Roadmaster EZ Base Plate Kit # 521433-1 is a direct connect style base plate and the Roadmaster Explorer is a crossbar style base plate, so the two unfortunately won't work with each other. I'd recommend using something different that works with direct connect base plates like the Roadmaster Falcon All-Terrain Tow Bar # RM-522

  • Recommended Flat Towing System For 2012 Jeep Liberty Sport 4WD Behiind 2005 Holiday Rambler 30PPD
    For your 2012 Jeep Liberty Sport 4WD, I recommend the Roadmaster EZ Base Plate Kit - Removable Arms # 521433-1 to start your flat tow set-up. I've attached a video of this installation to help. For a tow bar, I recommend the Roadmaster Falcon 2 Tow Bar - Motorhome Mount - 2" Hitch - 6,000 lbs # RM-520 along with safety cables # RM-643. Then for your tow vehicle wiring, I recommend the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267. This will give you a 7-way to 6-way...

  • Can 2012 Jeep Liberty 4x4 be Towed with Tow Dolly
    I did some checking and the 2012 Jeep Liberty 4WD is towable on a tow dolly like the # RM-2050-1 as-is as long as you follow the outlined procedures in the owners manual. Drive shaft does not need to be disconnected.

  • Flat Tow Parts for 2010 Jeep Liberty
    The Crossbars you identify appear to be Roadmaster Crossbar-Style Base Plate Kit, # 3136-1. This fits a Saturn Ion. For your 2010 Jeep Liberty, yes you are correct that you need the Roadmaster EZ Base Plate Kit with Removable Arms, # 521433-1 and this will match to your Roadmaster Falcon 2 Tow Bar, # RM-520. For wiring I suggest the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit, # RM-15267. If you need supplemental braking, I suggest the Stay-IN-Play DUO Supplemental Braking...

  • Recommended Flat Towing Parts for a 2012 Jeep Liberty
    You will need to purchase the parts separately there isn't one giant flat towing kit that can be purchased. There are just way too many options and combinations. We all tend to recommend different products so my choice in parts will be different but not necessarily better. The question you looked at is a few years old but they stopped making new parts for 2012 Liberty's awhile ago. To flat tow your 2012 Jeep Liberty you will need the following parts: Tow Bar and Safety Chains - etrailer...

  • Parts Needed to Flat Tow a 2007 Jeep Liberty Behind an RV
    There are several differences between the EZ5 base plates # RM-521423-5 and the regular EZ base plates # 521433-1. The biggest difference is what each of them fits. EZ5 base plates # RM-521423-5 fit the 2002 to 2007 Jeep Liberty. EZ base plates # 521433-1 fit the 2008 to 2012 Jeep Liberty. Since you have a 2007 Liberty you would need to use either the EZ5 base plates # RM-521423-5 or the EZ4 base plates # RM-521423-4. The difference between these is the design of the removable arms. There...

  • How Do Arms for Roadmaster EZ Plate Base Plate Kit Secure for 2012 Jeep Liberty
    The end of the shank for the arms of the Roadmaster EZ Base Plate Kit # 521433-1 have a collar (for lack of a better word) and then a longer flat piece that locks it into place once the arms are placed into the base plates and turned. You can see this demonstrated in the attached review video. Please note that a complete flat towing setup you will need a base plate kit, tow bar, safety cables, vehicle tow bar wiring, a supplemental braking system, and possibly a high-low adapter. If you...

  • Base Plates For 2011 Jeep Liberty Sport Without Rock Guard For Roadmaster Tow Bar
    I verified with Roadmaster with the correct base plate fit for your 2011 Jeep Liberty Sport without a rock guard, and it is different than the part you mentioned. The correct is the following: - Roadmaster EZ Base Plate Kit # 521433-1 According to Roadmaster, the # 521433-1 is compatible with all Roadmaster tow bars, including your Blackhawk All-Terrain. Insofar as revisions to the base plate number you asked about, that is not something that should be done as it will compromise the...

  • What Tow Bar is Compatible with Roadmaster EZ Base Plate Kit 521433-1
    The Roadmaster EZ base plate kits like the part # 521433-1 are basically compatible with all of the Roadmaster tow bars available. The most popular option though is the Roadmaster Falcon part # RM-520. This has telescoping arms that allow the tension in them to be released so that connecting and disconnecting is easier.

  • How to Use Blue Ox or Demco Tow Bars with a Roadmaster EZ Base Plate Kit
    No, the Universal Tow Bar Adapter for Roadmaster Direct-Connect Baseplate # RM62ZR will not work with your Roadmaster EZ Base Plate Kit # 521433-1. That base plate kit is a crossbar style and the adapters work for the Direct-Connect styles. But I do have an option for you. You would want to use the RoadMaster Base Plate to Blue Ox and Demco Tow Bars Adapter # RM-033 along with the Quick Disconnect Crossbar Assembly for Roadmaster Tow Bars # 910021-00.

  • Roadmaster Tow Bar Base Plate Kits for 2010 Jeep Liberty
    For the 2010 Jeep Liberty, we offer two different Roadmaster Base Plate Kits. Part # 521433-1 will fit Limited or Sport Models not equipped with rock guards, skid plates, or brush guards. Part # 521434-1 fits Limited or Sport Models with rock guards or skid plates, but not brush guards. Neither would be compatible with Renegade models. Both Base Plate Kits are Roadmaster EZ Plate Kits, which feature removable draw bars which make the base plates pretty much invisible once the draw bars...

  • Roadmaster Base Plates for a 2012 Jeep Liberty and BlackHawk Tow Bar
    Yes, you can use either # 521433-1 (if the Liberty does not have a rockguard or skid plate) or # 521434-1 (if it does have a rockguard or skidplate). Either set is compatible with your BlackHawk tow bar. You will also need safety cables like # RM-643. Next you will need a lighting solution. I recommend the plug and play Hopkins harness # HM56204 for the easiest installation. You will also need a supplemental braking system on the Jeep as required by law in most states. The easiest to...

  • Base Plates, Safety Cables, and Lighting Recommendations to Flat Tow a 2010 Jeep Liberty
    There are two sets of base plates that will fit a 2010 Jeep Liberty. If the Liberty has a rockguard or skidplate but no brushguard, you will need # 521434-1. If the Liberty has no brushguard, rockguard, or skidplate, use # 521433-1. Both of these base plates are EZ models and are compatible with a Sterling tow bar. You might also be interested in adding some safety cables or chains and a lighting kit as required by law. For safety cables, I recommend the RoadMaster 68 inch Single Hook,...

  • Recommended Base Plates for 2012 Jeep Liberty to Use with Roadmaster Sterling Tow Bar
    If your 2012 Jeep Liberty doesn't have a rockguard or skid plate then I recommend the Roadmaster EZ Base Plate Kit # 521433-1. If you do have a rockguard or skid plate then you will want the Roadmaster EZ Base Plate Kit # 521434-1, which will actually replace the rockguard/skid plate. Both of these options are directly compatible with your existing Sterling Tow Bar. Your current Roadmaster InvisiBrake # RM-8700 will also work great with your Jeep Liberty. If you are using a lighting solution...

  • How To Tell What Base Plate Kit is On a 2012 Jeep Liberty
    I have attached for you a list of base plate kit options we offer for a 2012 Jeep Liberty. If you compare these to what you have now, you should be able to find a match. You may then need an adapter to use the Roadmaster Blackhawk Tow Bar. If you have the Roadmaster EZ Base Plate Kit part # 521433-1 for example you will need the Quick Disconnect Crossbar Assembly part # 910021-00. Please let me know what base plate kit you come up with so I can see what adapter you'll need.

  • Base Plates for 2005 Honda Element for use With Roadmaster Falcon Tow Bar
    There are base plates for your 2005 Honda Element which are compatible with your Roadmaster Falcon Tow Bar # RM-522, but the # 521433-1 you mentioned won't fit, as those are for certain model years of the Jeep Liberty. So what you will need for your '05 Element are the exact base plates you mentioned, the Roadmaster Direct-Connect Base Plate Kit # 1541-5. Along with the base plates and tow bar, the other parts you will need to tow your '05 Element are as follows (if you do not have them): -...

  • Parts Needed to Flat Tow 2011 Jeep Liberty with Nighthawk Tow Bar
    For your 2011 Jeep Liberty there are only base plate kits from Roadmaster that require the use of a crossbar like the EZ Kit part # 521433-1 which you have currently. Some vehicles with heavier duty frames allow the use of the direct connect style base plates but this isn't available for every vehicle. Since the Roadmaster Nighthawk part # RM-676 does not come with the crossbar you need you'll need the crossbar kit part # 910021-00 as well.

  • How To Use Roadmaster Falcon Tow Bar On 2011 Jeep Liberty
    In order to use a Roadmaster Falcon Tow Bar on a 2011 Jeep Liberty (Without Rockguard or Skid Plate) you'll have to go with the Roadmaster EZ Base Plate Kit part # 521433-1 which requires the Quick Disconnect Crossbar Assembly part # 910021-00 if you don't already have it as that's the only option. In regards to a flat-tow wiring harness, it's hard to make a case against the Hopkins Custom Tail Light Wiring Kit part # HM56204 since it's both plug-in-play and cost effective. It also comes...

  • How Level Should a Tow Bar be to Flat Tow a 2008 Jeep Liberty
    When flat towing a vehicle behind a motorhome you want the tow bar to bewithin 3 inches of perfectly level. We call this the "safe zone" for flat towing. I've linked a help article for you. In order to help you get your setup level you may need a high-low adapter. I've also linked our selection of adapters for you to look at so you can choose the correct rise or drop you need to safely tow your 2008 Jeep Liberty. Another thing to check before attempting to tow the Jeep is the owner's...

  • Recommended Flat Towing Equipment For A 2008 Jeep Liberty
    To flat tow your 2008 Jeep Liberty you'll need a tow bar, base plate, tow bar wiring harness, braking system, and safety cables.

This tow bar with 2" ball coupler has stainless steel, telescoping arms that automatically lock into place. Large hookup radius allows you to connect without perfectly lining up your vehicle.

  • Base Plates, Lighting, Safety Cables, and Braking System to Flat Tow a 2011 Jeep Liberty
    In this case, the base plates for a 2005 Jeep Liberty will not fit on a 2011 Jeep Liberty. For a 2011 Jeep Liberty without brushguard, rockguard, or skid plate, you will need Roadmaster EZ Base Plate Kit, # 521433-1. For a 2011 Jeep Liberty with a rockguard or skid plate, but without a brushguard, use Roadmaster EZ Base Plate Kit, # 521434-1. The Falcon 2 Tow Bar, # RM-520, that you have referenced is compatible with either set of base plates listed above. To complete the towing set up...
