Proportional Braking

A vast improvement over "on/off" systems, which brake at a single pre-set level, the Patriot 3 has a proportional design for equal braking. The actuator inside your towed car applies the brakes with the same intensity that you apply to them in your RV. If you slam on the RV's brakes in an emergency situation, the Patriot II engages your towed car's brakes with virtually the same intensity. If you press the RV's brakes just enough to slow a bit, your towed car's brakes are depressed just enough to slow it down, as well. The result is improved control, better stopping and less wear on both your vehicle's and RV's brakes.

Jeep Patriot

Overall, the Blue Ox system has worked out great. I had read a lot of reviews, mostly positive, but some who had some difficulty with the installation, but in my case I had no real difficulty at all. The base plate lined up good, I did use a pry bar to spring it a bit, but nothing major. Ok, so this review if for the entire Blue Ox base plate, Blue Ox Alpha, Patriot II and Hopkings light kit package. I deviated a bit from the base plate installation procedure. I never used the vice grips, I simply installed the 5/8" bolts, leveled the plate and torqued them up after applying red Locktite. I was able to wedge/slip the spacer bars into position and then I drilled the frame using the base plate/spacer bar combination to keep the drill perfectly aligned. I did not have a 17/32 drill so I simply used a 1/2" drill to start each hole. I then swapped down to a 1/4" drill to punch through the frame and progressively drilled the hole larger until I got to the 1/2" bit. I have a Drill Doctor to keep my bits very sharp so they do not drift or wander. Great tool for your shop if you do not have one. I also drilled the hole toward the rear first. Once that was complete, I installed the rear most 1/2" bolt, Locktite and torqued that bolt. I then started a 1/2" hole using the base plate, swapped to the smaller bit and again progressively drill to 1/2" using the spacer as a guide and installed the front 1/2" bolt with Locktite and then torqued. I can see where if you installed the front bolt first, it would be difficult to reach the rear to get the nut started. I rechecked the torque on all the bolts once installed. Word of caution, the nuts have some "teeth" to bite into the frame when installed. These kind of nuts do not want to be tightened and loosened repeatedly. You want to install them once and go right to tightness. Less risk of breaking the wire that is welded to the nuts because the teeth are initially sharp and will bite into the frame. If you tighten and loosen these nuts the teeth get duller and will not grab very well. The purpose of the wire is only to align the nut with the bolt. I did slightly "kink" the wires on the bolts so the nuts started easily on the threads of the bolt. To refit the air dam underneath, I simply measured the distance between the left and right side of the base plate and transferred that dimension to the plastic dam. Rather than cut with a knife, I drilled a 1/2" hole in the plastic dam at the bottom end, used masking tape to mark my cut lines and then finished with a fine tooth jigsaw cutting 1/2" slots. Since the base plate is 1/4" thick the 1/2" slots give me a bit of play and look nice and even. I did not take photos yet, but if I can get back here I'll post a few of the finished product. Among the things I really like about this is how up tight and close the base plate connections are to my bumper. You really do not notice the base plate when you look at the front of the Jeep which to me gives it a nice clean look. I got a Patriot II remote braking system. It took me longer to route the "break away wire" and switch than to set up the remote control. The Hopkins brake light package was easy to install and directions were clear. Spent most of my time deciding how to route the wires from rear to front. 563947

I did a lot of research on these portable units and discovered that this blue ox patriot II has excellent reviews compared to other options. It is very easy to use compared to my old brake buddy system I had before. I relied on the recommendations I saw on an etrailer video and as usual they didn’t steer me wrong. I have a 2019 Equinox and a 1998 Jeep. It works well on both. Overall an excellent product sold by an outstanding company. 613814

  • Recommended Supplemental Braking System For Use With Multiple Tow Vehicles
    The best supplemental braking system for your situation is the Blue Ox Patriot 3 part # BRK2019 which is a portable braking system.

It is compatible with power assist brakes so if you decide to switch to a hybrid tow vehicle in the future the Patriot will be compatible. However, I have checked the owner's manual for the 2007 Honda Fit and it looks like Honda does not recommend...

  • Compatibility of Blue Ox BX4370 Ascent Tow Bar with 2015 Ford F150
    From what I've found, the 2015 Ford F150 will weigh between 4000 and 5000 lbs, depending on cab configuration and bed length. Since the # BX4370 Blue Ox Ascent tow bar is rated up to 7500 lbs, it'll work just great for you. You'll need a few other items to complete your flat towing system if you haven't chosen them already. You'll need base plates, a wiring solution, a supplemental braking system and possibly a high/low adapter. For base plates, I'd recommend the Blue Ox # BX2671....
