Upgrading from a Bulldog 2” coupler to 2 5/16 BD coupler

[Patriot]

Oliver Bulldog 2 5/16 coupler upgrade.

I decided to finally pull the trigger and upgrade our Oliver from a 2” 7000# Bulldog coupler to a new Bulldog 2 5/16” 12500 coupler. I also ordered a spare coupler repair kit. These 2 5/16” BD couplers are becoming difficult to locate and purchase with Bulldog filing for bankruptcy protection in Oct of last year😳.

It’s my understanding, that BD is no longer manufacturing and shipping these couplers to RV manufacturers possibly due to bankruptcy proceedings. (open source)  I did attempt to purchase a 2 5/16 BG coupler from Oliver and they no longer have this upgrade in stock and available to purchase and ship. Jerry at Oliver told me they have no idea if or when they will have this coupler in stock again and are seeking alternative options. Will there will be a restructuring with BD? Anyone’s guess. I will be taking the new coupler to a friend’s machine shop to have the holes precisely drilled. 

If you’re on the fence about upgrading to a 2 5/16  12,500 #coupler it might be a good time to search for a vendor that has one on the shelf and ready to ship.

A big thank you to @rideandfly for helping source this coupler! The Vendor I ordered from was Croft Trailer Supply in Kansas City, Mo.  Ended up myself, @rideandfly and @John Dorrer purchased the (3) they had in stock. If it’s an upgrade you’re considering you may not want to wait. 

 

Safe Travels!

Good idea. We did ours May 2025 when they were readily available. This upgrade sure provides a reassuring feeling when towing! 😎

Couldn't agree more.  JD, I like your lock setup better than my own.  What are you using and have you been happy with them?

Thanks, Steve. Hey, mine is nothing fancy. I searched for an older thread where several owners had posted more high-end locks and coupler covers but could not locate it today.

I do like this simple Curt coupler release lock, but one hit with a 5-LB hammer and the whole assembly would fly off: https://www.amazon.com/dp/B00T9N6H06/

The front ball lock I have is something that came with a used trailer I bought, not sure of brand name.

For me something simple and less expensive is a basic deterrent. I believe unless your trailer is attached to the TV it's easy prey to steal. It can be towed away regardless of our efforts! Anybody can chain any trailer to the rear of a pickup, regardless of what is used to lock the coupler.

Some buy expensive locks. Some have added an internal switch to prevent the jacks from being lowered (a really bad idea). This would cause additional damage because the thief would prefer to lift the jacks, but if you prevent that, they'll just drag 'er down the street anyway, damaging the jack(s) at a minimum and likely body or frame damage too.

I used to rent garages in Cicero IL which is not exactly a safe neighborhood! Did all I could to keep my old cars and bikes safe. When I stored a trailer long-term, I would chain and padlock the two wheels together through the holes in the steel rims. If towed away the wheels on one side would lockup/burn rubber which would look rather odd while being towed on a slant down the road. I would make the chain/padlock obvious to a prospective thief as an initial deterrent.

Lots of different opinions on this topic🤣!

Thanks.  Mine is less fancy.  In particular, the coupler lock is the Curt longer rod varient that wouldnt survive a decent set of bolt cutters much less a good hit with a hammer.  You are probably correct that it doesnt matter that much.

We use a long shank Brinks padlock in the 2" Bulldog coupler. It fits snugly without drilling and hang the chains on the emergency brake cable snap-hook:

Tried a short shank Brinks padlock in the new 2 5/16" Bulldog and it fits, too. After making holes in the new Bulldog, will sand and spray paint with aluminum finish for contrast.

We have used this coupler security and ABUS lock combo since we took delivery in June of 2020. Since it only takes less than 5 minutes to remove the BD coupler via the two bolts off the trailer tongue it’s a good deterent and better than nothing. Also when on the road it makes for an easy eye check during a walk around of our rig.

This combo continue to serve us well 6 years in. Both have strong reviews. I will use this collar and lock on the new 2 5/16 coupler.

Another plus with the  S/S collar, you cannot secure the collar on the coupler locking mechanism if the coupler is not properly locked down on the hitch ball. A nice little extra built in secondary safety feature. https://www.amazon.com/dp/B00HL2NM0K?ref=ppx_yo2ov_dt_b_fed_asin_title

I purchased my Oliver in 2022 with the upgraded Bulldog 2 5/16 coupler and have no regrets.  I also use this collar with a slightly different ABUS lock. EDIT: I will also say that I use this coupler lock when I am hitched (visiting somewhere, for instance) as security. AND on top of that, as I like to boondock, I use the Fort Knox Locks box when I am not hitched, along with the collar lock. It might seem like a lot, but I worry a lot less with this setup.

I'm sorry to hear about the issues with Bulldog. Hopefully they will straighten out and pull through.

Hopefully they will restructure like many companies do. Only time will tell.
