Wheel spacers

hey guys, I’ll be towing a travel trailer fully loaded with all my gear, around 5,800 with my 2015 trd sport with tow package. I already added air bags and distribution hitch,sway bar and a b&m super tranny cooler and have a scangauge, I was wondering if adding wheel spacers help the overall stable ride? Travel trailer is a 24” aluminum sportsman.

 

I would doubt they would make any difference sounds like your setup is pretty good.

 

Ok thanks

 

Not clear if you are adding "spacers" to add vertical height to the trailer, adding spacers to get the wheels further apart for a wider "stance", or something other.

• Adding vertical height is simply going to increase frontal area and add to the wind resistance. You'll see that result in lower fuel mileage. It may also increase your likelihood of sway issues as the trailer sides become more exposed. I wouldn't raise the trailer unless you need the clearance for plumbing drains hanging off the trailer's bottom side.

• Spacing out the rims horizontally will simply move the center of the wheel away from the center of the wheel bearings, which will increase the likelihood of wheel bearing failure.


Depending upon your towing speed and the shape of your travel trailer, on a TRD the one thing that might improve the tow is to fairing in between the truck and trailer by adding an old school camper top. Right now you're presenting 2 separate frontal areas to the wind, with any trailer buffeting transmitted back to the truck. By extending the cab's height back to the trailer, you'd only be making a single hole in the wind. If it helps to envision this, then think "passenger train".

That new "lockable space" would also allow you to carry rarely needed heavy items (tool box, spare propane, etc) in the back of the truck, rather than inside the trailer.

Just my 2 cents.

 

Thanks man, much appreciated.
