Features to know about

Built for the Biggest Loads: Up to 36,000 lbs GTW

When you’re hauling heavy equipment, large campers, or oversized trailers, you can’t cut corners on strength. This solid steel BulletProof Hitches 2-Ball Mount handles up to 12,000 lbs with the 2" ball and an incredible 36,000 lbs with the 2-5/16" ball. The 5/16" thick channel frame and 1/2" welded gusset keep everything rigid, even under maximum weight. It’s the kind of hardware that stays stable no matter how much you’re towing.

Keeps Every Trailer Level: 5-1/4" Drop and 4-1/4" Rise

Different trailers sit at different heights, and this adjustable mount makes leveling them easy. The 3-position channel lets you move the 2-ball platform up or down until your trailer sits dead even. Whether you’re switching from a cargo hauler to a boat trailer, the adjustable design saves time and keeps your rig balanced on the road.

Built to Last in Rough Conditions: Matte Black Powder Coat Finish

Towing gear takes abuse from rain, salt, and road grime, but this mount’s matte black powder coat finish keeps corrosion at bay. Underneath that is a nickel undercoat and zinc topcoat on the pins and clips for extra protection. Even after repeated use, the finish stays intact so you can leave it installed without worrying about rust creeping in.

Simple to Use and Swap: Dual-Ball Platform with Secure Pins

Switching between trailer coupler sizes shouldn’t be a project. The welded dual-ball platform flips easily between a 2" and a 2-5/16" ball—just pull the pins, flip it, and reinsert them. The included heat-treated steel pins and clips lock everything in place fast, so hooking up or adjusting your setup only takes seconds.

Heavy-Duty Construction You Can Trust: Solid CNC-Chamfered Shank

The solid steel shank slides smoothly into any 3" x 3" hitch receiver thanks to its CNC-chamfered edges. That clean-cut shape helps protect the powder coat from chipping while making install and removal easier. Built tough at every point—from welds to finish—this mount is made to stay tight and dependable through years of real towing work.

Video Transcript for Complete Breakdown of the BulletProof Hitches 2-Ball Mount for 3" Hitch

Presenter Hey everyone, it's Eve Angeline here at etrailer and today we'll be taking a look at our Bulletproof hitches. Two ball, adjustable ball mount with a maximum capacity of 36,000 pounds. So this is a two inch as well as a two and five 16th inch ball. So if you have different trailer couplers you can adjust it as needed. Now you will have a different weight capacity depending on which one you use on the ball platform. So for the two inch, that's gonna be a 12,000 pound maximum towing capacity.

And then for your two and five 16ths that's gonna be a maximum 36,000 capacity. So still very impressive. Now this is extreme duty. You have the black powder coat finish, matte black too, which will help resist corrosion, but your pins as well. If you've ever had to deal with rusted pins that you can't take off of the ball mount, well you have a zinc topcoat for these pins that weigh even with it out in the elements.

They will help resist rust. Now there are three positions for adjustments. So you can see how there's those different holes. You can have it top one, bottom one. These holes are two inches apart.

To take it apart, you can see how you can just take the clip out, take the pin out, and then you can easily adjust this up and down or even flip it around for using the different hitch ball. Now this includes two pin and clips for the ball platform fitting onto the ball mount. What it does not include though is the hitch pin for your shank to your hitch receiver. So you are gonna need to pick one up separately. Make sure it matches your three inch hitch receiver.

And you can even take a look at some of our options like the infinite rule locking pin set if you wanna secure your ball mount. Now since this is made of a solid steel, it's super heavy duty, but if you just want to flip it over and switch it from rise to drop, it's actually pretty easy to do. Now there are two hitch pinholes here. That way you can have different adjustment for how far past your hitch receiver you want it to be. So we're going to put it on the furthest hole, but each hole is about two inches apart, which gives you a little bit of option there. So you may want to use the other one depending on where your bumper or your fascia sits. We have this on a motor home. You can have this on a truck as well, as long as you have that three inch hitch receiver. So we measure from the center of that hitch pinhole on that receiver to the closest point, which is this fin. That's going to be six inches away. The length this entire ball mount adds to the back of our hitch is going to be about 15 and a half inches. It gives you about four inches rise or drop. But for more specific measurements, we measure from the top inside edge of your hitch receiver right here. So the maximum rise is going to be four and a quarter inches. The maximum drop or the droppiest drop is going to be five and a quarter inches. So if you want to compare this with maybe some other brand options a close one is the CURT adjustable two ball mount. So very similar design. It has two balls, going to adjust up and down. The main difference is going to be the capacity. This has a maximum capacity of 36,000 pounds while the CURT's maximum capacity is in a 20,000 pound range. So definitely a difference there. If you do like this style, you can get this exact same ball mount with a different rise and drop. But check out our product pages and our pictures and our videos if you want more information so that you can get the right ball mount for you. But this right here right now was a quick look at our Bulletproof Hitches two ball adjustable ball mount right here at etrailer.com..

@Galen That's great to hear Galen! Thank you so much for coming back and sharing that with us.

The height adjustment was perfect for finding the right height for my boat trailer’s hydraulic brake’s to work properly. I pull it with a Chevy Express conversion van which is closer to the pavement than most tow vehicles.
by:
Great hitch! Very solid. Was a little bigger than expected but no issues. Makes switch between trailers so much easier
by:
This is my 2nd bulletproof hitch. My other one is to big to use on my truck. But it works great for my Tahoe. I am going to start shopping with you guys from now on for the things I want and need that you carry. There's 2 reasons why, first you have good prices but the thing that really won me over was the crazy fast shipping.
by:
It is heavy buy a locking pin so you don’t have to take it off
by:
Not my first time dealing with Etrailer and definitely not my last. Easy ordering and on time every time. Hitch is built very well exactly what we needed to tow our skid steer around. Seems very solid compared to otehrs we looked at.

Thanks etrailer.

The product was delivered as promised and I have had the opportunity to try it. I'm very happy with it. Some reviewers complained about noise, so I was pleasantly surprised at how quiet my connection was especially compared with my previous hitch. I am very confident that will me meet my towing needs!

Their packaging is, would you say...bullet proof? [slaps knee] haha! What are you towing with such stout equipment?

by:
Rust starting to show and coating has worn off. Rep suggested this drop length and it is definitely too much even with my 2500. Not a product flaw a customer service flaw
by:
Fit truck and trailer better than expected. Pulls heavy trailer very well. That is why I bought locks to try and keep the hitch from being taken.
by:
Very high-quality hitch! The shipping was FAST!

I need a solution for my BMW SUV to tow my boat and trailer with two ball sizes and very different height requirements. This worked perfectly. The name Bulletproof fits well - I was pleasantly surprised by the quality and engineering.

So far I am extremely happy with this hitch. It is very heavy duty. My towing capacity has changed and needed to upgrade to a heavy duty hitch. I have no doubts this is going to be Bulletproof!! It is very well built and a solid shank.

We're processing the return right now Kevin.

I purchased the 2-1/2" Bulletproof Adj Ball Mount for my 2019 RAM 2500 (Laramie, 4WD, 20" Rims&Tires, Off-Road Suspension) to have 1 mount for various trailers. This replaces various 2" mounts used on my 01 Silverado 2500. This is one serious, substantial piece of equipment! Heavy, good welds, nice powder coating! Pix compares this mount with a 7500# 2" Draw-tite mount. Nothing wrong with the Draw-tite, but no comparison in mass.
Some measurements, if interested: Truck: inside top of Receiver: 25" above grade. Bottom of mount without balls: 9-3/4" above grade (clearance). With 2-5/16" ball up: At lowest point: Top of Ball: 17" above grade. bottom of 2" ball: 9-1/4" above grade (clearance). At highest point: Top of Ball: 26-7/8" above grade. With 2" Ball up: At lowest point: Top of Ball: 16-1/2" above grade; bottom of 2-5/16" ball: 8-3/4" above grade (clearance). At highest point: Top of Ball: 26-1/2" above grade.
etrailer shipped quickly, only in original box from Bulletproof, with no exterior shipping box, but box was completely taped, so package arrived in good shape.
1 minor complaint: no pin included for securing mount into receiver.
by:
I am totally shocked by the weight and quality of the product. Not even one scratch on the finish. It shipped from Illinois to Dallas in only 3 days for free. Now I know why they are called BulletProof. Perfect for my lifted truck. I wished I had gotten this a long time ago!

It has worked out great. I have used it extensively on 5 different trailers with our 6 lifted truck. Not only has it been extremely versatile but overloaded tongue weights as well.

by:
I bought this hitch just under one year. To date, the hitch has performed fine. HOWEVER, the cheap powder coating has turned the entire hitch into a an eyesore. Its just rusting like mad, and the powder coat is now flaking in large chunks. Looks like crap on the back of the truck. I don't even live in an area where salt accumulates or they use it on the roadway.

This is not common as the hitch is covered with a high quality powder coat. If you ever get any paint chips or scratches on this ball mount, we recommend using a rust-oleum type of paint to cover those scratches. That will help with any corrosion as time goes on. I have a link for your reference below.

  • Fit of BulletProof Adjustable Ball Mount on 2018 Ford F350
    As long as your 2018 Ford F350 is equipped with the 2-1/2 inch hitch, and the distance from the inside bottom edge of the receiver tube of the hitch to the ground is between 12-18 inches, the BulletProof # MD254 Hitch adjustable ball mount would work great for you. The ball mount provides a 2 and a 2-5/16 inch ball. If your F350 is equipped with the OEM 3 inch hitch, you'd want to use # ED304 instead. You might also consider a keyed-alike locking pin set, part # 34061674-D which secures...

  • Looking For Fixed Ball Mount Similar To Curt C45518 But For A 3" Hitch Receiver
    Hey Bruce, thanks for reaching out. We do have fixed ball mounts for a 3" hitch. They aren't exactly "identical" to the Curt # C45518 you mentioned, but we do have something similar. Take a look at the following: - Curt Heavy Duty Forged Ball Mount for 3" Hitches - 2" Rise - 4" Drop - 21,000 lbs # C45430 This has 2" of rise instead of 3/4" rise, but that'll be the closest we have that fits a 3" hitch. If you need something that has less than 1" of rise, you'd have to go with an adjustable...

  • Is There a 3-Ball Ball Mount For 3 Inch Hitch With 5 Inch Drop
    Hi Tommy; that's correct there isn't a 3-ball ball mount for a 3 inch hitch with exactly a 5 inch drop. The closest is a 4-1/2 inch drop like you said with the 21,000 lb max capacity B&W Tow & Stow 3-Ball Mount # BWTS30048B. There is another option with a bit closer to the drop you want - 5-1/4 inches - but it's a 2-ball mount. I know you asked for the tri-ball but I did want to just throw this out there as an option. For that you would need the 22,000 lb max capacity BulletProof Hitches...
