by:

the 1st one received was stuck on the truck. TI had to really fight to get it off of there. The replacement one does the same thing but I am able to get it uncoupled. Just takes some effort to do so.



by:

Latching mechanism is vey troublesome gets stuck on the ball



by:

bolted right on, is rated above the trailer weight limit so I'm sure it will hold up. So far easy to hook up and unhook.



by:

Well built heavy duty product. Will be a huge improvement over the chinese coupler that come on my new dump trailer. Also plan on installing one on my tag trailer.
Great price and also super fast shipping
I will certainly use etrailer again

Same issues as the elcheapo chinese couplers. When you have to use prybars and set the trailer brakes and rock the truck back and forth to break the couple free its a real pain. I have went back to pintle hitches.



by:

replaced a cast coupler on a new trailer as I felt it not safe to pull a 22 foot trailer with a load. Works great.

Sold trailer. Purchaser happy with upgraded hitch, purchase price reflected upgrade. Pulled 20 ft container office to AZ and dead headed back. 3500 miles no issue.



by:

Replace a coupler that was held on with 2 bolts after 1 bolt failed. Love the security and strength this one has with 3 bolts. Have had issues with couple not releasing from the ball. Gets stuck in the locked position.



by:

Completely satisfied and extremely grateful for this item. Very strongly built. We use it on our 3 axle trailer hauling feed for our farm animals.



by:

I would not buy this again (T4855300). I took it off my trailer. I give etrailer 5 stars.



by:

Super fast shipping along with great pricing. Hitch showed up just as described and bolted right into place.



by:

Held up nicely even with many dry runs on the ball.



by:

Exactly what I hoped it would be. Old style American excellence. Heavy-duty and holes and bolts were perfect. Fast delivery too. I don't get to praise much of anything these days :)



by:

I just installed it. Awesome. Perfect fit and very well built.

  • What Size Mounting Bolts Does The Titan Bolt-On Coupler T4855300 Use?
    The Titan Bolt-On Coupler for 2 5/16" Ball - Primed - 21K # T4855300 you were looking at gets mounted using the included 5/8" x 6" long grade 8 bolts. Your trailer will need to have a channel on it that is 3" wide with mounting holes that are 2" apart on center. I included a video of the # T4855300 for you to take a look at.

  • Can Titan 21K Bolt-On Coupler be Used for a 14K Trailer
    As long as your adjustable bolt holes are 2" apart (see attached photo) the Titan Bolt-On Coupler # T4855300 would be a great option! The coupler being rated for more than the GVWR of the trailer can actually be a good thing. Just be sure that you don't exceed the weight rating of your trailer as this will not increase the rating of your trailer unless your current coupler is the limiting factor.

  • Trailer Coupler Recommendation for 16k Trailer
    Trailer couplers are not rated for tongue weight capacity. They are rated for Gross trailer weight, as long as the gross trailer weight is within the capacity of the coupler, the coupler is installed properly and the trailer is designed properly, the coupler will handle the tongue weight of the trailer. Proper installation of the coupler is the key to it handling the weight it is rated for and the manufacturers directions should be followed explicitly. For a 16k trailer the part # T4855300...

  • 6-Hole Weld-On Channel Bracket For Dexter 21K Bolt-On Coupler
    There sure is; Titan is actually Dexter now, but there is a 6-hole weld-on bracket that you can use with the coupler. The exact parts you need are as follows: - Dexter Bolt-On Coupler for 2 5/16" Ball - Primed - 21K # T4855300 - Demco 6-Hole Adjustable Channel Bracket - Weld On - 12" Tall - 21,000 lbs # DM66134 The Dexter coupler and Demco channel both have 2 inch spacing between mounting holes which is why they are compatible.

  • Replacement Adjustable 2-5/16 Coupler Rated for a 21,000 GVWR Trailer
    We do have a very similar replacement coupler that is rated for 21,000 GVWR, and it is the Titan Bolt-On Coupler # T4855300. The angle that your photo was taken I can not tell if it is a 2 or 3 hole adjustable coupler, but this Titan part is a 3 hole adjustable, 2-5/16 coupler that is rated for 21,000 pounds. This coupler fits 3-1/2 inch wide trailer tongue channels with 4 or 6 hole leveler channels. This assembly includes the coupler that has a primed finish, 3 Grade 8 bolts that are...

  • Recommendation for 2 Inch Ball, Bolt-On Trailer Coupler
    I have a solution for you, but Titan does not offer their Bolt-On Coupler for 2-5/16 Inch Ball # T4855300 in a 2 inch hitch ball design. For a bolt-on trailer coupler with a trigger latch, designed for a 2 inch ball I recommend the Demco Trailer Coupler, Adjustable Channel Mount, # DM12688-95. This coupler will mount in a 3 inch channel, like # DM59601, and has a weight capacity of 12,500 pounds. This is the highest capacity adjustable mount coupler we offer for a 2 inch hitch ball. There...
