As I went to mount my weight distribution hitch yesterday, I found my old locking pin was too short for the width of the GX receiver. Can anyone confirm a set that works well for the GX + trailer (same key)? I would prefer a right angle design for easier access.


Suggests a 4" length is needed.. Review: 2024 Lexus GX 550 towing reveals virtues and hassles, but I may have to try a 3.5".

Thanks,

Out of necessity, I grabbed a 4" drop at my local wallymart and it came in a "fused ball" drop w/ a lock. The lock that came with it worked fine, and fit without issue removing the trim, which is also annoying. These trucks need a 3.5' long usable pin, which I found out just the same. My Master stainless set no longer works so I am on the hunt for a new set as well. I thought Land Rover hitches were annoying with the proprietary hitch style, these are not far off with the bumper setup.

Same camp hear with mounting our Yakima bike rack which had a threaded pin and lock. I used a longer pin I found kicking around but had to ditch the lock and rack stabilizing. I wrapped the rack with 2 wraps of the 1" wide silicone stretch tape in two places to minimize movement.
 
This is my Hitch and Locking Hitch Pin from Proven Industries that's currently on my F150 but will go on my GX. They have some nice security features and they will key all your pins and locks the same if that's your desire.

I pull an ATV trailer with 2 Utility ATV's

I tightened it to 80-100 ft-lbs. I based those specs on lug nuts and the fact that it keeps loosening, but you are right, the U-bolt has bent. Seems fine so far and can be removed/installed without issue.

Thanks, certainly makes sense but contradictory to the Trimax's website. I called and they claimed yes, only hand tighten and when I told them that's not what the packaging said, they ask me what I want.

It seems that it's working for you and what you're doing makes sense, thanks..

Waiting for my GX till the next big trip.
 
Hi all, I reinstalled the bully back bumper guard I had on my GX460 to my GX550. We are on ferries a lot and got a few times softly rear ended as the cars are loaded very close to each other, so the bully guard addressed this concern for good. Finding the right lock pin was a challenge though given the different size of the GX550 tow hitch and as I wanted to keep the upper tow hitch cover. I got this one from Amazon and it fits well once you position the rubber rings on the lock pin properly.
