Enhance your towing capacity with Blue Ox's BX88185 Tow Bar Bracket. This high-quality adapter bracket set is designed to replace traditional lug-style brackets on your Blue Ox tow bar, making it compatible with Roadmaster base plates. Coated in a durable powder finish, this bracket ensures long-lasting resilience against wear and tear. The product comes with all necessary mounting hardware, making installation a breeze. Ideal for anyone looking to upgrade their towing capabilities, the BX88185 Tow Bar Bracket from Blue Ox is an undeniable asset.

Blue Ox is known internationally for recreational and commercial towing products, manufacturing in Pender, Nebraska since 1925. The line covers tow bars and vehicle-specific baseplates for flat towing behind a motorhome, sway control and weight distributing hitches, supplemental braking accessories and towing wiring, backed by patented designs and long-standing customer service.
Blue Ox has manufactured since 1925 and is recognised internationally for towing products and customer service. The company operates from Pender, Nebraska, where it grew out of Automatic Manufacturing Co., a business that started with cattle oilers and developed into agricultural equipment, tractor accessories and trailer towing hardware. That agricultural engineering heritage still shows in how the towing products are built, and the company holds patents across weight distribution, fifth wheel and tow bar designs.
Flat towing is the discipline Blue Ox is best known for. Towing a car with all four wheels on the ground behind a motorhome demands a system that stays rigid under braking, articulates properly over uneven ground, and connects to the towed vehicle at points strong enough to take the load. Blue Ox tow bars handle the first two, with self-aligning arms that latch under tension and release without a struggle when the load is off them. Vehicle-specific baseplates handle the third, engineered per make and model to tie into structural mounting points behind the fascia.
The wider flat towing range covers supplemental braking systems, safety cables and the accessories that make a complete legal setup, along with baseplate wiring and dinghy towing harnesses that pass lighting signals to the towed vehicle without back-feeding its electrical system.
For conventional trailer towing, Blue Ox weight distributing hitches with integrated sway control transfer tongue load onto the tow vehicle's front axle and resist the yaw that crosswinds and passing trucks induce.
The company describes its foundation as customer service, designing around what owners actually ask for, and it runs an RV park adjacent to the factory where customers can stay. Sister operations at the same Nebraska site include Automatic grain roller mills and MAD-RAMPS pivoting ramp systems.

The BX88185 Adapter Kit is designed to adapt Blue Ox tow bars to Roadmaster brackets that are already equipped with a cross bar. It allows you to connect a Blue Ox tow bar to an existing Roadmaster bracket installation.
The BX88185 Adapter Kit is designed for Roadmaster brackets that are already equipped with a cross bar. The manual does not specify whether it works with all Roadmaster bracket models or only certain versions.
The kit includes: 2 Roadmaster Adapters (61-5639), 8 washers (290-0381, .051 x .523 ID x 1.375 OD), 2 Essna Jam Nuts (202-0143, 1/2"-13, zinc plated), 2 Hex Head Bolts (201-0645, 1/2"-13 x 2", short thread, zinc plated), and 4 plastic spacers (290-0347, 1/16" x 13/16" ID x 2").
The kit includes all fasteners needed for installation. You will need the existing bracket pins from your Roadmaster bracket to complete the attachment. No additional parts are required beyond what is included.
Installation has three steps: (1) Remove the existing tow bar lug from the leg pivot, (2) Install the adapters to the tow bar leg pivots using the hex bolts, nuts, and washers, (3) Insert the adapters into the attachment tabs of the bracket, align the holes, and pin in place using the existing bracket pins.
Install the two adapters (61-5639) to the tow bar leg pivots using the hex bolts (201-0645), jam nuts (202-0143), and washers (290-0381). The manual does not specify the torque value or the exact assembly sequence for these fasteners.
Insert the adapters into the attachment tabs of the bracket, align the holes of the adapters with the holes of the bracket, and pin in place using the existing bracket pins that came with your Roadmaster bracket.
