Options to Add a Brake Actuator to an Off-Road Trailer  


Would this work with a 2600 lb trailer? Want to add surge brakes to an off-road trailer that uses a pintle ring. Would changing the spring inside compensate for the weight rating difference?


Expert Reply:

As the Demco Hydraulic Brake Actuator # DM8759422 uses a compression shock that is designed specifically for this, it will not be able to be replaced with a smaller spring. That being said, this is pretty highly rated for a 2,600 pound trailer. Unfortunately, we do not have an actuator like this with a lower rating at this time.

What may be a better option, will be to go with an electric over hydraulic actuator, like the HydraStar # HBA16, and then pair it with the Lock N Roll Articulating Channel Tongue # 336TS508 for the trailer and the Lock N Roll # 336VS501 for your hitch. You will need to have a brake controller that can handle electric over hydraulic systems, like the Redarc # RED44FR, and a 7 Way on the back of your 2004 Lexus LX 470. If you do not already have a 7 Way, you will need to add the Universal Installation Kit for Trailer Brake Controller # ETBC7.
