The tab for the cylinder mount could have been welded on a little more to the right to make it better. At least an inch to allow the air actuating cylinder to be directly in line with the brake pedal

This is the second jeep that I have used the road master seat adapters on and they both have needed modifications to fit and they still don’t fit like they should. They will get the job done but for the price of these brackets, I would expect a much nicer fit.

After waiting 12 days for arrival of this part, I was surprised how BAD the fit is. You really have to wrestle to get this adapter installed, I gave 2 stars because of this difficulty. Eventually I did get it installed only see it does not line up with the brake pedal very well on my 2021 Jeep Overland Gladiator. I used the extra large bolt provided, which did not help the install at all being it did not have a lead-in tip like the factory bolt, so don’t understand why it was required it looks obnoxious sticking up from seat bracket after install. I may replace it with factory bolt and a thick washer.

The adapter did not line up very well with the seat bolts. I had to take the seat out entirely to get the adapter to fit. I had to finagle it to even be able to get the seat bolts back in. The peg for the connection to the brakemaster did not line up with the break pedal. I had to bend the breakmaster connector for it to work. Installation was not as clean and simple as it could have been if the part had been machined properly.

- Correct Roadmaster Seat Adapter for BrakeMaster System on a 2018 Jeep JL Wrangler UnlimitedHey Kevin, thanks for reaching out! You'll need the Seat Adapter # RM69FR for your 2018 Jeep JL Wrangler Unlimited. This is used for both the BrakeMaster # RM-9160 and the BrakeMaster # RM-9060 for motor home air or hydraulic brakes respectively. You'll also need the Stop Light Switch # RM-751490 to keep your brake lights working correctly.
view full answer... - Recommended Flat Towing Setup for a 2022 Jeep Wrangler Willy's Tony, if it were me, I'd go with the Roadmaster Direct Connect Base Plate Kit # RM-521453-5. This kit is going to work with any Roadmaster direct-connect style tow bars, will work with both the factory plastic and steel bumpers, and has hidden brackets so it will sit even farther than standard kits which still lets you retain that "from the factory" look when not using it. You'd also need a set of clips # RM-910029 which lets you connect the base plate to the tow bar. If you're needing...
view full answer... - Flat Towing Equipment Recommendations For A 2021 Wrangler Unlimited 4Xe RubiconTo flat tow your 2021 Jeep Wrangler Unlimited 4Xe Rubicon Hybrid you will need a tow bar, base plate, tow bar wiring kit, braking system, and safety cables. I have the following recommendations for you listed below: Tow Bar: Roadmaster Nighthawk All Terrain, Non-Binding Tow Bar w/ LED Lights - RV Mount - 8K # RM-676. This tow bar features non-binding latches and a large hookup radius to make connecting/disconnecting from your vehicle on any terrain a breeze. It has integrated LED lights...

- Complete Flat Towing Setup And Bumper For A 2022 Jeep WranglerFor your 2022 Jeep Wrangler, I recommend taking a look at the: -Aries TrailCrusher 1 Piece Front Bumper for Jeep # AA2156002, with the Blue Ox Off-Road Bumper Adapters for Blue Ox Motorhome Mounted Tow Bars # BX88357. We do not actually offer a complete aluminum bumper for your 2022 Jeep Wrangler, we just off the center sections, which are made of aluminum. However, this bumper is made from carbon steel, and also features center cutouts for OE bumper lights, a standard winch mounting...
view full answer... - Roadmaster BrakeMaster System RM-9160 in 2018 Jeep JL Wrangler Unlimited with Diode KitThe Blue Ox 4-diode tow bar wiring kit # BX8848 that you have installed in your JL Unlimited will not cause issues with the brake lights on the Jeep since it will be in Tow Mode when you are flat towing it. This will allow the motorhome to control the lights. In your 2018 Jeep JL Wrangler Unlimited the Roadmaster BrakeMaster System # RM-9160 will install using a Stop Light Switch kit # RM-751000 which provides a separate "brakes on" signal path back to your motorhome. To use this braking...
view full answer... - Complete Flat Towing Setup for a 2021 Jeep Wrangler Unlimited Hey Brent, so I recommend going with Roadmaster for the majority of your setup. Both brands are great and will ultimately get the job done, but Roadmaster has become a very trusted brand in the industry and has a very good track record which is why I'd recommend them over Blue Ox. So with that being said, for a set of tow bars I recommend checking out the Roadmaster Nighthawk All-Terrain Tow Bar w/ LED Lights # RM-676. This tow bar has a nice 8K capacity, an integrated LED strip for easy...
view full answer... - Correct Seat Adapter for Roadmaster BrakeMaster When Used with 2021 Jeep GladiatorThe correct seat adapter for the Roadmaster BrakeMaster # RM-9160 to use it with your 2021 Jeep Gladiator depends on if you have the Mojave or not: - NON-Mojave Jeep Gladiator: RoadMaster BrakeMaster Custom Seat Adapter # RM69FR - Jeep Gladiator MOJAVE ONLY: RoadMaster BrakeMaster Custom Seat Adapter # RM87VR
view full answer... - Roadmaster BrakeMaster Seat Adapter to Fit 2019 Jeep Wrangler JLActually yes. The new seat adapter that fits the 2018 and 2019 JL Wranglers is part # RM69FR for non-diesel models and the # RM87VR for diesel models. The old seat adapter from your JK, part # RM-88130, doesn't fit the new Jeeps.

This means you will need the Roadmaster BrakeMaster # RM-9160 for your 2022 Jeep Wrangler Rubicon. You will also want the BrakeMaster Custom Seat Adapter # RM69FR to make installation much easier.
view full answer... - Reasonably-Priced Supplemental Braking System for Flat Towing 2021 Jeep Wrangler Behind MotorhomeWe don't carry the Ready Brake tow bar braking system, but we do carry other supplemental braking systems for flat towing a vehicle. For a 2021 Jeep Wrangler, the most reasonably priced option we offer is the Roadmaster BrakeMaster, part # RM-9160 which would also require the # RM69FR seat adapter and the # RM-751490 stop light switch to function properly. You'll also need base plates like the # e98948 you'd looked at, a tow bar, safety cables, a wiring solution and possibly a high/low...
view full answer... - Roadmaster Brakemaster Seat Adapter for 2021 Jeep Wrangler Unlimited The correct Roadmaster BrakeMaster # RM-9160 seat adapter for a 2021 Jeep Wrangler Unlimited is the part # RM69FR or the part # RM87VR if you have the EcoDiesel engine.
view full answer... - Tow Bar and Braking System Suggested for 2021 Jeep WranglerUnfortunately, we don't offer the Hercules tow bar or the Ready Brake but we do have some reasonably priced tow bar and braking system options that would work for you which would be compatible with the Blue Ox # BX1139 base plates you'd looked at. For a 2021 Jeep Wrangler, I'd recommend the Blue Ox Avail tow bar, part # BX7420. The generous 10000 lb capacity combined with the fact that the tow bar is self-aligning and non-binding make this the perfect choice of tow bar to go with the #...
view full answer... - RoadMaster BrakeMaster Custom Seat Adapter for a 2018 Jeep JL WranglerYes, the correct RoadMaster BrakeMaster Custom Seat Adapter for the Roadmaster BrakeMaster Braking System part # RM-9100 on your 2018 Jeep JL Wrangler is part # RM69FR.
view full answer... - Custom Seat Adapter For RoadMaster BrakeMaster Braking System On a 2022 Jeep Gladiator Willys TrimThe RoadMaster BrakeMaster Custom Seat Adapter # RM69FR is the correct part for your 2022 Jeep Gladiator Willys. This will allow you to connect to either the BrakeMaster Hydraulic # RM-9060 or BrakeMaster Air # RM-9160 depending on your braking system on your tow vehicle.

Contacted RoadMaster and etrailer, came to the conclusion that I should have installed RM87VR in my Gladiator Overland, etrailer quickly sent this unit, I installed it over the outer track and under the inner track with their hardware. It fit much better and aligned perfectly with my brake pedal. Sent RM69FR back, waiting difference refund. Much Happier with the customer service this time around. Happy Camper Here!
