Easy Hookup with Long, Self-Aligning Arms

Blue Ox Ascent Self-Aligning Arms

The Ascent's convenient, self-centering arms help to make hookup a snap. Older and more economical tow bars have rigid arms that are essentially locked in place so you have to drive your towed vehicle into the exact position necessary for hookup. But with the Ascent, you can connect from the approximate towing position quickly and easily. Once you have connected the tow bar to your vehicle's base plates, simply drive your RV forward until the tow bar arms fully extend and lock in place. Before hitting the road, be sure to check that the arms are properly latched to avoid damage to your towing setup.

The Ascent's arms are also longer than the arms on the average tow bar. As a result, they provide an improved turning radius, making it easy to maneuver around obstacles and execute sharp turns.

Non-Binding for Simple Disconnect

Blue Ox Ascent Non-Binding Tow Arms

Being unable to unhook your car because of a bind in the tow bar is really frustrating. And the tight spots and uneven terrain at some campsites can put your tow bar into a bind, even if you're careful.

Fortunately, Blue Ox has defeated the age-old problem of binding by creating a tow bar that is just as easy to release as it is to hook up. Simply press down the handles on the tow bar arms until the internal latch disengages. By releasing some of the static pressure from the tow bar, you can move the arms just enough to make disconnecting your car a snap, even if it's not perfectly lined up with your RV.

Sturdy, Dependable Triple-Lug Connection

Blue Ox Ascent Triple-Lug Connection

The Blue Ox base plates on your vehicle are equipped with two tabs each that connect to the brackets on the ends of these tow bar arms. The triple-lug design of the Ascent tow bar creates a tight, stable connection by surrounding both base plate lugs. The result is a sturdy, reinforced connection that is strong and rigid for a safe, dependable towing experience.

Hooking up the Ascent to your base plates is as simple as it is secure. Just line up the triple-lug end of the tow bar arm with the base plate so that the center lug is positioned between the two tabs of the base plate. Then insert the 1/2" keeper pin through all of the lugs and secure it with the included quick pin.

Heavy-Duty, Vinyl-Coated Safety Cables Included

Blue Ox Ascent Safety Cables

The vinyl-coated safety cables, which have a 7,500-lb weight rating, provide added protection should the tow bar ever disconnect during towing. Steel hooks connect each cable to your towed vehicle's base plates and to your motorhome's trailer hitch.

Simple Storage

Blue Ox Ascent Easy Storage

The Ascent can be easily stored on your RV when it's not in use. Once the arms are disconnected from the base plate, just fold them together so they are side by side. Then swing the arms toward your RV, sliding the integrated pin into the bracket located on the shank of the tow bar to secure it in place. Finally, push the arms down so they are parallel with your RV's bumper.

Guide to Flat Towing

Flat towing your vehicle is much more convenient than using a trailer or a tow dolly. These other options take up much more storage space, leaving you less room both at home and at the campsite. In addition, securing your vehicle to a trailer or tow dolly can be a hassle and more time consuming than hooking up with a tow bar.

There are 5 basic components needed when flat towing a vehicle: a tow bar, a base plate kit, a safety cable set, tow bar wiring, and a supplemental braking system.

Towing Basics

The tow bar links your towed car to your motorhome. It attaches to the custom-fit base plates that install on the frame of your towed car. Safety cables ensure that your towed car does not separate from your motorhome in the event that your tow bar becomes detached. Tow bar wiring allows your towed vehicle's signal lights to sync up with your motorhome's tail lights, which is required by law in most states. Finally, the supplemental braking system - also required in most states - brakes your towed car when the brakes in your motorhome are activated, preventing wear on the motorhome and decreasing braking distance for your entire setup.

  • Flat Towing Recommendations For A 2016 GMC Sierra 2500
    There's a variety of reasons depending on the vehicle but one of the main reasons I've seen across most vehicles is that it could effect the steering wheel lock and you could end up dragging the tires instead of them turning with the RV. I HIGHLY recommend following everything it says in your owner's manual to ensure the safety of you and your vehicle while flat towing. The battery being disconnected will cause it to drain if you hook up the brake controller to it so I recommend the...

  • Can 2011-2017 Jeep Compass Be Flat Towed With Manual Transmission
    I looked at an owner's manual for a 2014 Compass online, because it's midway through the model year span you mentioned and saw that manual transmission equipped Compass models can be flat towed with the ignition in the ACC position and the transmission in neutral. The owner's manual doesn't mention anything specific about a 4WD vehicle, but typically if the transfer case can be placed in neutral as well, flat towing isn't an issue but I'd recommend checking with a Jeep dealer for clarification....
