Offroad Trailblazers and Envoys

Drop Trailer Hitch Ball Mount

Trailblazer and Envoy related, but not off-road related...

I use my TBSS to pull trailers. I own 2 and my brother owns 3. Between them, they range from 300-7,000lbs and use all 3 common ball sizes. Of coarse, the tongues are also all at different heights.

So, what's worked well for people? I felt NO need for antisway nor load leveling with the stock SS suspension. With the lifted height and the Z71 spring (instead of air bags) I'm not sure. I did pull one around 4,500 last week. It was ok... but not great.

Anyone try this yet?

That will make it worse. Anything you do to give the trailer more leverage will make it worse. (more leverage, meaning the distance from the ball to the rear axle) Try this:

It would also be best to get modify the one (I assume you have only one) trailer that's demanding the 1 7/8" ball. UHaul makes their couplers fit either size ball, and you'd think that the 1 7/8" ball size would just die from disuse except for those little $100 dump trailers that could be attached to the vehicles with zip ties in a pinch.

Here is the ball kit that I run and you can use with the one that Mike listed. http://www.etrailer.com/Balls/Convert-A-Ball/900b.html

I've never needed anti sway bars. I hear they help a lot. Has anyone felt the need to use them behind a lifted TB? What about load distribution system?

Mike, that was my #2 choice. Thanks for reminding me about the leverage behind the rear axle. I think that had crossed my mind, but I'd forgot. The advantage of the tri ball is that I'd only need one. Disadvantage would be, it' harder on my trailer hitch (I've caught it moving against the frame within the bolt hols) and probably lessens the stability of the coupled unit. Pros and Cons! I suppose it depends on how often am I changing trailers, and how far/often/fast am I pulling the heavier ones.

I've thought about converting my 4x8 to a 2" ball. It's a little dump that I built up a little. I love the trailer but it will not fit a 2" ball. I wish they just built them that way in the first place. It can't cost much more!

You can get DIY 2" ball couplers for under $15. That's not too expensive. :poke:

When I rebuilt my little trailer, I welded everything that had been bolted. So, I have to decide if I want to cut it off. Time and money!

I'm not lifted, although I do have the 3/4" spacers in front, and 30.6" tires. I probably have the worst-case scenario for towing -- over-sized tires, 3.42 gears, NO extra tranny cooler, hauling a 5400 pound trailer up through the mountains. I've only done it 3 times, and it's obviously a huge strain on the vehicle.

I pull my boat with a harbor freight drop hitch through my CBI tire carrier. Boat and trailer weight ~ 3600lbs. No issues.

Probably because you are pushing the max weight for the 3.42s with OEM tires.

Actually the max for my truck (2004 I6) is 4800 pounds. I knew what the limits were, but it still pulled pretty well, even though I did make a stop at one point just to let things cool down. Oh, and I also don't have load-leveling or anti-sway on the trailer, its just a homebuilt straight hitch, dual-axle with its own brakes.

I'm not saying I recommend this setup, I'm just saying it can be done. Since I'm getting ready to swap to 4.10 gears, its not something I'll have to worry about in the future.

Does your HF drop hitch make a ton of noise? I borrowed one from AJ (hotness) to tow dolly Joe (Hatchet) out to Matt (Regulator) for an engine swap. Noisey obnoxious hitch!

I've found a few. I had one for a while. It was my brothers. I was tired of his BS so I returned his trailer hitch and took my trailers home. lol

I don't think it does, my trailer has surge brakes so any noise I hear while braking I've always figured it was that sliding forwards and back. The only time I hear anything is when I stop/ start.
