Question

Question:

Dear Andrew. Thank you very much for your promptly answer. This is an aluminum trailer, I prefer to not make modifications to the chassis like weld o add a 2” tube reinforcement to hold the Timbren Axle-Less Trailer Suspension System. If prefer to weld and accomplish by professionals the mounting flange and go to electric brakes using my axle and splinde. Please let me know all the parts I need to do that, also the dash actuator part number, switches and connectors. Thank you very much.

It is possible to weld on a brake flange such as Brake Mounting Flange for 1-3/4" Round Trailer Axles - 2K # 4-34 for 1-3/4" round axles, but it takes a qualified welder and even then it can be difficult to accomplish. A better solution is to upgrade your current axles with something like Timbren Axle-Less Trailer Suspension System - Spindle w/Brake Flange - Regular Tires - 2,200 lbs # ASR1THDS01, or if you need lift spindles you can go with Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle w/Flange - Regular Tires - 2.2K # TASR1THDS04.

These suspension systems can be bolted or welded onto your trailer and you may need to use 2" square tubing for reinforcement. These have brake flanges already installed onto them, so you can simply add a brake assembly like Dexter Electric Trailer Brake Kit w/ Parking Brakes - 7" - Left/Right Hand Assemblies - 2.2K # K23-103-104-00 then add a hub and drum assembly such as Dexter Trailer Hub and Drum Assembly for 2,000-lb Axles - 7" - 5 on 4-1/2 # 8-257-5UC3.

Your axle should be 1-3/4" in diameter in which case you can use Brake Mounting Flange for 1-3/4" Round Trailer Axles - 2K # 4-34; I recommend measuring just to verify your axle size. Then you can install a brake assembly such as Dexter Electric Trailer Brake Kit w/ Parking Brakes - 7" - Left/Right Hand Assemblies - 2.2K # K23-103-104-00. Next you will need a hub/drum assembly and for this I recommend Trailer Hub and Drum Assembly - 2K Axles - 7" Diameter - 5 on 4-1/2 - L44643 - Pre-Greased # AKHD-545-2-1K. Now you will need to convert your trailer's wiring to 7 way so that it can be compatible with a brake controller. For this, I recommend using 7-Way Molded Connector w/ 15' Cable - Trailer End # 50-67-103. I attached a 7 way pinout diagram to help with the install. If your tow vehicle already has a 7 way then you are good to hook up the trailer, but it probably has a 4 way flat in which case you will need to install Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge Wires # ETBC7 which provides a 7 way connector compatible with brake controllers. Last but not least, you need a brake controller. I recommend the Tekonsha BRAKE-EVN Trailer Brake Controller - 1 to 4 Axles - Proportional # TK63VR because it is very easy to use and works well. I attached some demonstration videos for you to check out.

There isn't a way to convert a latch, and there aren't any yoke latch repair kits unfortunately, so the best we can offer is a replacement A-frame coupler. If you want to stick with the yoke-style latch you can use the 8,000 lb…

You will want to orientate the Brake Mounting Flange for 1-3/4" Round Trailer Axles - 2K item #4-34 so the dimples face outward from your axles.

That isn't the sort of figure that is factored into brakes. What you need to choose the right brakes is your axle's capacity, which is going to lead you in the right direction in terms of the brakes you need. For example, a 3,500 lb…

I have a product that may work for you as we do not carry any torsion trailer axles like the one under your 10'X6' Aluma utility trailer. The Timbren Axle-Less Trailer Suspension System #A20RS545 is rated for 2,000lbs and will mount to the…

It is a very good idea to keep spare bearings and seals (and wheel bearing grease too) on hand for the unexpected roadside stop. We have individual bearing and seal parts like #L68149, #L44649 and #58846 as well as kits like #BK2-100 that combine…

The 4 hole brake mounting flange will work for 10 inch brakes because the 7 inch and 10 inch assemblies use the same 2-7/8 inch on center mounting holes. The brake assemblies like #AKEBRK-35 or self-adjusting assemblies like #AKEBRK-35-SA will both…

That is the correct hole size for brake mounting flange #4-34. That would leave space for an approximate 1/8 inch weld all around the spindle. Because welding on brake flanges is a precision job it is recommended to have a professional welder with…

Answer 9

The 5 on 4-1/2 bolt pattern of a hub or wheel such as #AM20365 means that there are 5 lugs and, if you drew a circle that passed through the center of each lug the diameter would be 4-1/2 inches. I have included some links and a picture that will…

The recommended hub/drum size for a 13" diameter wheel is one that is for 10" diameter brakes. The wheel will still fit on the hub/drum assuming the bolt pattern matches there is just less surface area on the hub for the wheel. However, you…

A BT8 spindle would have a diameter of .99 of an inch where the bearings would both install and would have a diameter of 1.24 where the great seal would ride. That would require a hub part #AKIHUB-440-2-1K for an idler hub. A BTR spindle would have…

It is possible to triple tow (1 tow vehicle + 2 trailers) when both trailer's have brakes but this would mean that the brake output wire that runs from the brake controller in the tow vehicle to both trailers would need to be at least a 6 gauge…
