Availability of 8 on 6-1/2 Hub and Drum Assemblies for the Timbren Axle-Less Suspension ASR35HDS02  

Published 05/04/2018



Question:

Thanks for the quick and thorough response, Jon. I'm going to be running 37x12.50x17 all terrain, E load rated tires on the truck. Would I be better off moving up to a heavier duty axle? The trailer is a 7x16 run-of-the-mill cargo trailer except it's 7 ft tall inside. It weighs around 2500 pounds empty and currently has 3500 lbs axles. The plan is to turn this into somewhat of camper that can handle some very light off-pavement travel, so I may end of with MAYBE 3,000 lbs worth of interior build out, solar panels, full water tanks, batteries, and random cargo in it. Will a heavier duty axle make the ride too stiff for this trailer, or would the stiffer springs be more desirable considering the potentially rough roads anyway? I've never used the Timbren suspension, so I don't know what to expect ride-wise. It's got to be better than the creaky leafs that are on it now!

We do have some hub and drum assemblies that you can use with the Timbren Heavy-Duty Axle-Less Trailer Suspension # ASR35HDS02 which have an 8 on 6-1/2" bolt pattern.

Our Trailer Hub and Drum Assembly # AKHD-865-7-2-EZ-K has a 12" diameter and comes with the needed bearings and grease cap for your application. It does come with a grease seal, but you will need to use part # GS-2125DL (Qty 1) or part # RG06-090 (Qty 2) for the correct seal for the smaller spindle.

If you don't already have the brake assemblies I recommend going with our self-adjusting assemblies. You need part # AKEBRK-7L-SA for the left hand and part # AKEBRK-7R-SA for the right hand.

Please note that we do not recommend using passenger vehicle tires for a trailer application. Passenger tires have more flex in them to make the ride more comfortable while trailer tires have a sidewall that is more stiff. This allows the tire to handle the weight much better and will increase the life of your tires.

Let me know what size tires you have on your pickup and I can recommend some trailer tires that come in a similar size.

Since the combined weight rating of two 3,500 lbs axle (or axle-less in your case) systems is 7,000 lbs they will not have a problem carrying your weight. The only thing that you need to check is the weight capacity of the trailer itself so that you don't overload it. In all honesty you don't necessarily need the bigger tires, but since you are wanting tires that are close to the same size that you are using on your truck I recommend going with the Taskmaster Provider 235/85R16 Radial Trailer Tire with the Silver Mod Wheel # TA26FR. This tire has a section width of 9.25" and has a 31.7" overall diameter. It comes in a load range G (4,400 lbs at 110 psi) and has a speed rating of 81 mph. The wheel that comes with it has the 8 on 6-1/2" bolt pattern that you asked about. You do need to make sure that you have the proper clearance on your trailer for this larger tire. When it comes to the ride quality of the Timbren Axle-Less systems over a traditional axle, the Timbrens will increase it quite a bit! Some applications require that a 2" x 3" steel tube be run across the frame of the trailer from one Timbren to the other, but aside from that you should see some extra ground clearance. Since the suspension is independent of each other you will also see that it ride much more smooth over bumps. People who take their trailers off-roading love these systems!
