Video Transcript for Curt Ball Mounts - Fixed Ball Mount - C45055 Review

Today we're going to be reviewing part number C45055. This is a Curt Class III Ball Mount with a 1-7/8-inch hitch ball. The starter kit has everything that you need to tow. This ball mount is going to provide a drop or rise to fit your application. It's going to come with the included 5/8-inch pin and clip to secure this inside of your hitch and the hitch ball is going to come already torqued to factory specifications. That way this unit is ready to be used right out of the box. Here on the hitch ball, this is a 1-7/8-inch hitch ball.

It's going to feature a chrome plating so it is designed to resist rust and corrosion. It's got the nice little wrench flats on here. That way if you ever need to loosen it up and flip it over so you can use the mount in the rise position, you can easily do that. It's also going to feature a 1-inch shank diameter. The ball mount itself is made from a steel construction featuring a black powder-coated finish for superior rust protection. Now this is designed for 2-inch by 2-inch trailer hitch receivers.

It's going to offer a gross towing weight of 3500 pounds with a maximum tongue weight of 350 pounds and those capacities are limited to the hitch ball. A few measurements to go over real quick. I'll take a measurement from the center of the hitch pin hole to the center of the hitch ball hole. That's going to give us a measurement of 8-1/4 of an inch. The overall length of the unit measuring from end-to-end, is going to be about 12-1/2 inches. Now if we want to use this in the rise position. That'd be this position here.

It's going to offer a 2-inch rise from the inside top edge of the receiver tube to the top of the ball platform. We want to be really careful when installing this because we want to make sure we have enough clearance from the rearmost part of our vehicle to the upright portion of the mount here. A measurement that can assist you in determining if this will work in the rise position on your particular vehicle, is measuring from the center of the hitch pin hole to the back of the upright portions. If we do that measurement, I'm measuring to the base of the weld. That's going to give us a measurement of 4-3/8 of an inch. When installed in the drop position, measuring from the inside top edge of the receiver tube to the top of the ball platform, it's going to give us a max drop of 4 inches.

You can see here on the back side it's going to feature a hollow shank and the entire unit is going to be covered by a limited lifetime warranty. Now I want to show you how to install this inside of your hitch. A pretty simple process. All you have to do is take the shank of the ball mount, slide it into your hitch until you get your pin holes to line up with one another and then take the included hitch pin and clip to secure it inside of your hitch. That's going to do it for today's review of part number C45055. This is a Curt Class III Ball Mount with a 1-7/8-inch hitch ball. .

I purchased this hitch to pull my utility trailer with. It was easy to order, arrived on time, and simple to install/use. This hitch is built very well and strong, and has a good coating finish on it. Great product!


Comments
Trailer hitch has performed very well, no issues with it. Happy with the purchase.

The Curt trailer hitch and wiring harness for my 2016 Highlander was a perfect fit. Installation was a breeze just following the etrailer videos. I opted for the 4" drop ball mount because of the Highlanders ground clearance but the standard 2" drop would have been just fine. Will use etrailer again without hesitation.


Comments
The Curt Trailer Hitch and Vehicle Wiring Kit have worked just fine. Thanks to the etrailer videos, the installation was easy. I have recommended etrailer to several friends contemplating after market hitches.

Review from a similar Curt Steel Ball Mount in Trailer Hitch Ball Mount


My complaint here is not with etrailer but with Curt. I put a Curt hitch on my Hyundai Sonata, perfect fit but because the Sonata is so low, the receiver is only 10" off the ground. I initially ordered a 5-3/8" rise drawbar but it did not have a long enough bar for the vertical portion to clear the bumper. I am having to use one with a longer bar but the rise is only 2-5/8" which put the trailer tongue lower than it should be. Curt designed the hitch for this low vehicle, they should make the 5-3/8" rise drawbar with a longer bar. etrailer knows their stuff and this is the only solution. The small single axel utility trailer I will be pulling will be lightly loaded so it will work OK but it will be angled down more than it should be. etrailer was super about swapping it out for me.


Comments
Fair. I shorten the chains as much as possible but they still drag some.

Review from a similar Curt Steel Ball Mount in Trailer Hitch Ball Mount


I have two of these. My first I bought two years ago. I very highly recommend this Curt Class III Ballmount 2" Drop because of its price, durability and quality. I towed various class 3 loads with ease and confidence with this ballmount. It slides into the hitch and does its job without fail. It looks excellent after towing a load.

etrailer's price is about as good as it gets and delivery is very speedy.


Comments
The Curt Class III Ball Mount with 2 Ball - 2 - 7,500 lbs is a very high quality, very heavy duty piece of towing equipment. I highly recommend it for anyone, professional or home user, for mid-level towing jobs.

This drop hitch has been fantastic from day one. This product is very heavy-duty and secure for hauling the heavier loads on the flat-bed car hauler and the boat trailer. Very impressive. Thank-you.

Excellent - Couldnt ask for anything better.

Review from a similar Curt Steel Ball Mount in Trailer Hitch Ball Mount


I have purchased several Curt Heavy Duty Forged Ball Mounts in different drops.
We tow 35,000 miles a year with several trucks but are only towing app. 3,000 to 7,000 lbs. I need a mount that will take the rough roads and the long haul without any worry. I feel good using this heavy duty mount and ball even though it may be over kill. I have used Curt products for several years and found them to hold up to all our tough towing needs.

Review from a similar Curt Steel Ball Mount in Trailer Hitch Ball Mount


Heavy duty ball mount and great capacities. Marked down one star due to having about 3mm of play inside of my gen 2.5 Tundra's 2inch receiver hitch. I will have to mount a set screw or find another solution for the excess play.
