The three most common lug stud sizes for a trailer are 1/2"-20, 9/16"-18, and 5/8"-18. In order to make sure you get the correct lug nuts you need to measure the lug studs on the trailer now as we have no way to look this up for…

So the install of a spindle like the #TRU97FR really needs to be done by a welder who has done the job before and has the special jigs for the job. It's a precision job and we can't recommend a method for it aside from taking it to someone…

A trailer as old as yours would be pretty hard to determine an overall capacity for, but since you have 6 lug hubs that would indicate by todays standards you have a capacity most likely between 5,200 and 6k which matches pretty close to the spindle…

All of the TPMS sensors we carry are closed systems so they wouldn't be compatible with the GM sensors you have, you would need to get these from GM directly. I also can't speak to the fitment of GM's sensors with the stems on a 5th wheel…

I do have an option for you but the GM TPMS uses a proprietary software, you cannot use another sensor with the program even if they operate on the same frequency per TST. I do know of many others who have run into issues with GM not offering a…

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.

The OEM prep package consists of 4 "pucks" in the bed of the truck that will allow you to drop in puck style hitches for easy installation and removal, that gives you a completely clear bed when not in use. The B&W Companion OEM 5th…

The difference between the Class II and Class III hitches has to do with their Gross Trailer Weight (GTW), their Tongue Weight (TW), and their Hitch Receiver Size. Class II trailer hitch receivers have a 1-1/4 inch receiver and can be rated up to…

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…

You can use leaf springs that are rated higher than the axle without any issues as long as they measure the correct measurement for your trailer. For example the 6-leaf double eye spring for 7,000 lb axles part #e64SR measures 24-7/8" eye to…

Even though I cannot comment specifically on the grease you used because I am not familiar with it, I can tell you the best grease for trailer bearings is a a grease with a rating of GC-LB, which just means it is made to withstand very high…

Thank you for providing the specs for the suspension components that you already have. Correct hanger spacing really depends on the components being used such as springs, hangers and equalizers. Most of the hanger spacing dimensions that we have are…
