Replacement head unit fits Curt A20 fifth-wheel trailer hitches.


Excellent product - nice & smooth operation during towing (works well in conjunction with LCI Rota-Flex pin box. Easy to hook/unhook. etrailer provides good prices and free shipping. I am very satisfied and would recommend this purchase to others.

Hitch still works as intended. Im very happy with the hitch.
Brad - 08/10/2021


Was very pleased with the condition and build quality of this product. I've towed with it 1 time so far. It works great. Very easy to install and couple to my 5th wheel. My only issue is the powder coat is flaking off on the front of the 5th wheel plate. I'm going to add a photo. Right side of opening is where it chipped.

I recommend using a rust resistant paint like Rustoleum to touch up the 5th wheel hitch.

Legs and 5th wheel head purchased separately fit my new 2020 Sierra 2500 HD perfectly. Directions to assemble were easy to follow. Thank you etrailer


Great price, great product , fast shipping and fabulous service! Very simple to assemble and install.


This hitch was very easy to install. It did come missing one of the bolts to attach the head to the base. I contacted George at etrailer customer service and he sent the replacement bolt out ASAP and I got it in just a couple of days. Got the hitch completely installed and it seems to operate just fine. Haven't towed with it yet but it functions fine. I highly recommend for their outstanding customer service.


Received my Curt A20 Fifth Wheel Head, but have not had a chance to try it out yet. I am very pleased with the quality of its' components and from what I read of the reviews, most had nothing but praise for this F.W. Hitch. etrailer has a great product at a great price and the shipping was free. Thanks.
