Video Transcript for Curt Weight Distribution C17123 Review

Today we're going to be taking a look at part number C17123. This is the Curt weight distribution shank. It's going to have a ten-hole adjustment. This portion of the mount is going to slide into the receiver tube of our hitch; that's going to provide the attachment point to get us secured in the hitch and then here on the front face is where our attachment points are located for mounting our weight distribution systems head assembly. This is designed for use with current weight distribution systems. Again, you're going to have the ten-hole adjustment for attaching the head assembly; that's going to let you level your trailer with your tow vehicle; a lot of options there. The drop low rise position is available with this unit so that way it can fit your particular application.

With it installed on the hitch, and this pointing down towards the ground, that's going to be the drop position. This position here would be known as the rise position. This is a welded steel construction. It's very strong and durable solid steel so we don't have any hollow points except our mounting holes. It's going to have a really nice textured black powder coat finish on it, so it's going to stand up really well against rusting and corrosion. Again, this is designed for 2"x2" trailer hitch receivers.

It's going to give us a weight capacity of 15,000 pounds with a towing weight capacity of 1,500 pounds. We're going to take a few measurements real quick. Take a look at the overall length. What we're measuring is from the center of one outer pin hole to the center of the outer pin hole on the other side of the adjustment shank. If I take a measurement center on center, that's going to give us a measurement of 11-1/4". These holes, you can look down that ruler there; these are going to be separated on center from one another by 1-1/4".

That measurement's going to be consistent all the way down through those mounting holes. When used in the rise position, this is going give us a maximum rise of 8-7/8". That measurement is going to be taken from the inside top edge of the receiver tube of our hitch to the top of our ball platform. That would be with our platform mounted at the highest setting, again, 8-7/8" rise. Maximum drop would be 5-5/8". The diameter of our hitch pin hole to get us secured in our hitch, that's going to measure 5/8". A few more measurements.

From the center of the hitch pin hole to the back of the shank is going to give us a measurement of 3". From the center of the hitch pin hole to the closest point of the support bar, that's also going to measure 3". Now from the center of the hitch pin hole to the back of this upright bar right here, it's going to give us a measurement of 6", and then from the center of the hitch pin hole to the center of the pin holes here for the head assembly, that's going to give us a measurement of 7". Overall length back to front is going to be about 11". Overall length of the adjustment bar here with the holes in it, 13-1/4". That's going to do it for our review of part number C17123. This is the Curt weight distribution shank.

Its heavy duty and fit however the metal wasn't cleaned good before manufactured. Ot had large chunks of paint coming off that was powder coated over. I didn't buy it because of its looks but one would think it would be cleaned before welding and powder coated. Not etrailers fault because it was built in China according to the box. 654350

Great product at a great price. 522246

Product as described , heavy duty & works great .. 491591

- C17123

I chose this one because it didn't stick out as far as the others but still had sufficient drop for my 5" lift on the Avalanche with a trunion style WD hitch (higher than bar). It's mounted on the 2nd and 3rd lower holes and I chopped off the bottom one to prevent dragging. Works great! 572521

Perfect ammount of drop for my camper to ride level behind my 2019 2wd suburban. 756527

etrailer delivered on time as promised and I had no problems with the order. The product was as described and works perfectly with my Husky Centerpoint hitch. The large adjustment range lets me level my trailer when towing with my 3/4 ton Silverado. I have now towed my trailer about 15,000 miles with it and had no problems. 720186

Just what I needed thanks 691811

etrailer customer service is outstanding. I needed a long drop down receiver for my lifted truck and Meghan L talked with me on the phone for about 45 minutes. We did measurements and looked for a while to make my trailer ride level. Meghan was very helpful and the product has been top quality. Thank you for all your help. 675042

- C17123

I just purchased a Ford F-250. Needed a longer shank for my Husky weight distribution hitch for my travel trailer. This will work perfect. One issue I had was the weld on the receiver part of the shank protruded so that my 2 1/2" X 2" reducer sleeve wouldn't slide in all the way keeping my hitch pin from sliding through. A little hack saw work and now everything works great. 669144
