Video Transcript for Review of Titan Straight Tongue Trailer Coupler - Standard Coupler - T4845000

Today we're taking a look at the Titan Zinc Plated Lever Lock Coupler.Now this unit mounts to your trailer and allows you to connect your trailer to your tow vehicle.The lever lock coupling mechanism ensures easy, secure connection to a two inch hitch ball.So basically when you're ready to use it, what you'll need to do is you'll need to remove the included pin, it's tethered on there so you don't misplace it or lose it. That can be replaced with a locking pin if desired. But then you slide this ball, it's like a half ball right here, you put your finger on the finger indention area, slide it over and then lift up the lever.Now that fully opens the coupler to receive a two inch ball. Once the ball engages, it will push back down that lever, it will click into place. That audible click lets you know that it's fully engaged and you're ready to reinstall your pin and get on the road.Now the unit itself is made from a durable steel construction with zinc plating to resist rust and corrosion, it's a bolt on installation, two mount holes on each side of the unit. Parts are made in the U.S.A.

Again, it's designed for a two inch ball.The space right here, inside edge to inside edge measures about three inches so that lets us know this is for a three inch wide channel tongue. The bolt holes on the unit, these are separated apart from one another on center by three inches and they have a half inch diameter. Mounting hardware not included.All your capacities are engraved right here on the top. So, this unit features a 5,000 pound gross load capacity, 750 pound tongue weight capacity.Then when it comes to the overall length of the unit measuring from the very front to the very back you can see it measures about 11 inches long.That's going to do it for today's look at the Titan Zinc Plated Lever Lock Coupler.

Average Customer Rating:  4.7 out of 5 stars   (20 Customer Reviews)

Corrosion-resistant, straight-tongue trailer coupler features a trigger-style latching mechanism that securely locks in place around your 2" hitch ball.


Used this coupler to replace the aging and obsolete folding surge coupler on my dated and neglected Nautique Ramlin trailer. Deleted the surge system and this bolted up perfectly. Super easy and smooth operation for locking onto the tow ball.


Creates a locking challenge. Needs a special lock. The open slide is not smooth and sometimes hard to work. The coupling is a challenge on any slope. Sometimes we need to drag the trailer to a flatter spot to get it to engage.


Exactly the part it says it is. Working well for me.


PRO: Arrived well packaged and undamaged. Good tight fit on the 2" ball.

CON: I was replacing an older Titan coupler. The new coupler's bolt holes did not match the old coupler's hole pattern - off by 1/32" to 1/8", so the bolts will not fit thru the matching holes in the trailer. Rather than a 15 minute replacement, I now have to drill out the trailer bolt holes to make the new coupler fit, meaning that I will not have the close tolerance bolt-to-hole fit. This looser fit can ultimately cause wear on the bolts. I now plan to put in a bolt replacement maintenance exam/replacement reminder every year (to be safe).


Awesome coupler. Solid contact with the ball, super low profile, easy to use latch , this is exactly what I wanted as I run a bike rack above the coupler, plenty of clearance for unhitching the trailer without removing the rack.


I have two different vehicles with two different hitch ball diameters. I purchased this coupler to allow me hassle free use of either vehicle with the trailer equipped with the coupler.

The couple is a very clever design and should allow me the flexibility that I was looking for. I haven't had a chance to use it yet, but it looks great and I am considering putting them on all of my smaller trailers.


This coupler worked out great for my trailer tongue. I like the type of mechanism that is used to connect to the trailer ball. The old trailer coupler has been very problematic when I tried to make a connection.


Only place I'll shop. Outstanding service and delivery.


Works perfectly. Bolted on easily.


Product is exactly what I ordered and it came within two days. Will definitely buy from etrailer again.


Product as advertised!

See what our Experts say about this Dexter Straight Tongue Trailer Coupler

  • Why Would There be Rattle Between Trailer Coupler and Hitch Ball
    If your current coupler is loose enough that it rattles when connected to a hitch ball it is in need of adjustment or replacement. There should be a nut on the underside of the coupler that holds the latch in place. You would want to tighten that down so that the latch fits tighter to the hitch ball. The Titan Coupler part # T4845000 would also be a great replacement as long as your trailer frame is built on 3 inch channel. This coupler is also made in the USA.

  • How to Make Titan Zinc-Plated, Leverlock Coupler Fit 2-1/2 Inch Trailer Tongue
    You can get the Titan Zinc-Plated, Leverlock Coupler # T4845000 to fit your 2-1/2 inch x 2-1/2 inch square tube, although there is not an adapter sleeve. Instead, you will need to have spacers welded onto the tongue in order to use this coupler. This is going to ensure the strongest connection of coupler and trailer. I have added a link to a video review for you to check out as well of the Titan Zinc-Plated, Leverlock Coupler # T4845000.

  • Converting Trailer with A-60 Surge Coupler to Electric Brakes
    The Titan Zinc-Plated, Leverlock Coupler # T4845000 that you referenced is designed to fit on a trailer tongue that measures 3 inches wide. If you measure the width of the insert portion of your surge coupler and it's 3 inches wide this will easily fit in place of it. The other option is to fuse the coupler you have now. You basically could run long bolts through the outer and inner sections of your current surge coupler and you would have turned it into a fixed coupler. I also attached...

  • Mounting Bolt Holes of Titan Coupler
    You can absolutely use the holes on the top of the Titan Zinc-Plated, Leverlock Coupler # T4845000 as holes to bolt on the coupler; in fact that is their exact purpose. I'm not sure which video you were watching specifically, but this is not a weld-on coupler due to its zinc plating which can be more difficult to weld. I have added a link to a video review of this coupler or you to check out.

  • Recommended 50-MM Couplers For Straight Trailer Tongue
    I recommend the Titan LeverLock Coupler # T4845000. This is an adjustable coupler that will work with 1-7/8 inch, 2-inch and 50-mm balls. This coupler is a bolt-on and has a 5,000-lb capacity. For a coupler that uses a handwheel to tighten the coupler around a hitch ball I recommend part # T2343400183. This coupler will also work with 1-7/8 inch, 2-inch and 50-mm balls, and is a bolt-on installation with a 5,000-lb capacity.

  • Trailer Coupler Compatible with European 50mm Hitch Ball
    Yes, as long as the tongue on your Shoreland'r Tadpull Trailer does not exceed 3" wide then you can use the Titan Zinc-Plated, Leverlock Coupler part # T4845000 which is compatible with 50mm hitch balls like part # 63912. It also has a weight capacity of 5,000 lbs so you will need to make sure your boat and trailer do not exceed this. The Titan Coupler is zinc plated for corrosion resistant and comes with a one year warranty. I have attached a review video for you as well.

  • Repair Kit for Titan Zinc-Plated Coupler # T2343400183
    I spoke with my contact at Titan, and he said that your Zinc-Plated Coupler # T2343400183 with the handwheel and the Titan Leverlock Coupler # T4845000 are manufactured differently, so the mechanisms are not interchangeable. You will not be able to use the leverlock mechanism to replace the handwheel assembly on your coupler. We do have the Titan Latch Repair Kit # T4045400 that will allow you to repair the handwheel latching mechanism on your existing unit. The kit includes the lock...

    The Coupler Lock # e98888 will work perfectly with the Titan Leverlock Coupler # T4845000 to help protect your trailer while it's in storage. This heavy-duty pin simply takes the place of the existing pin on the coupler to either prevent a potential thief from coupling the trailer to his/her tow vehicle when it's in storage or actually lock the trailer to your hitch ball when you're out on adventures. I have attached a short video review that you can check out as well.

  • Repair Kit Availability for a 5125 Valley Coupler
    Since Valley went out of business there are no direct replacement parts that are available but a repair kit like the Curt # C25194 for 2" Curt Couplers may be compatible. What I recommend doing is replace your coupler completely as replacement parts for Valley products are becoming increasingly harder to find. If your trailer has a 3" channel then the Titan Zinc-Plated, Leverlock Coupler # T4845000 would be a great replacement as it is rated for 5,000 lbs and is compatible with both 1-7/8"...

  • Recommended 2" Bolt on Coupler for a Folding Tongue Trailer
    The Titan Zinc-Plated Coupler item # T4845000 will work with a fold away tongue so long as it has a 3" channel. There isn't a way to increase the length. This coupler has a 500 lbs capacity and fits a 2" ball. These couplers are quite a bit smaller but all close to the same size. For a larger coupler you will have to go up in capacity. I recommend the Demco Channel Tongue Trailer Coupler item # DM15000-52. The Demco has an EZ-Latch that makes hooking up your trailer extremely easy. This...

  • Best Trailer Coupler Lock For a Titan Zinc-Plated, Leverlock Coupler # T4845000
    The AMPLock Trailer Coupler Lock # AMP84FR is the most secure lock we carry for your Titan Zinc-Plated, Leverlock Coupler # T4845000. This lock uses a laser cut style key and the cast iron construction prevents damage from shock and cutting tools. The shape of the lock fits the front of your square style coupler to ensure it is secure as you do not have the lip profile that a traditional coupler lock like most locks are designed to secure.

  • Availability of Straight Coupler Replacement for Titan Aero 7500 Brake Actuator # T63FR
    The Titan Aero 7500 brake actuator, part # T63FR, has a 2-inch ball and fits a 3 inch wide channel tongue. It has a weight capacity of 7,500 lbs. In a straight bolt-on coupler with a 2 inch ball that fits a 3 inch wide channel, the coupler with the highest weight capacity would be the Titan Leverlock Coupler - Adjustable Ball, part # T4845000. This coupler will only have a weight capacity of 5,000 lbs, which is lower than the 7,500-lb capacity on the Titan Aero 7500 brake actuator. The...

  • Can Welded On Broken Trailer Coupler be Replaced
    We don't have generic coupler repair kits that I can recommend, but most likely your coupler can be replaced if you take it to a qualified welder in your area. They should have no problem removing the coupler and installing a new one. If your hitch ball is 2 inches the part # F343000301 would work for you. This mounts to a 3 inch channel. If you have a 1-7/8 inch ball you would want the part # T4845000.

  • Trailer Couplers Compatible with 50mm Hitch Ball
    A 50mm hitch accessory, such as a hitch ball like # 63912 or # EH53C-C, is slightly smaller than 2-inches, 1.968-inches to be exact. There are multi-fit couplers like # T4845000 and # T2343400183 that will work fine with three hitch ball sizes, 1-7/8-inch, 2-inch and 50mm. The 50mm size did indeed originate in Europe. I recommend using only a coupler that is designed specifically to fit the 50mm ball size.
