Weight Distribution Diagram

Create a more stable ride for your tow vehicle and trailer with a weight distribution hitch. Adding spring bars to your towing system applies leverage, which transfers the load that is pushing down on the rear of your vehicle to all the axles on both your tow vehicle and your trailer, resulting in an even distribution of weight throughout. The result is a smooth, level ride, as well as the ability to tow the maximum capacity of your hitch.

Selecting a Weight Distribution System

The tongue weight rating is the most important factor in determining which size weight distribution system you should use. If the bars of the system you choose are rated too high for your setup, they will create a rigid ride, which can result in a bouncing trailer. If, on the other hand, the bars are not rated high enough, the system will be unable to properly distribute the weight, rendering it virtually useless.

To determine the proper weight rating for a weight distribution system, you must first determine your trailer's tongue weight. Then add to that the weight of the cargo behind the rear axle of your tow vehicle. These two measurements make up the tongue weight rating for a weight distribution system.

Forged Steel Spring Bars

The round spring bars are made from forged steel, giving them a distinct advantage over typical cast steel bars. Forging is a process where thermal and mechanical energy are applied to the steel, resulting in a finished product that is more resilient to impacts and is stronger in terms of shear strength. Simply put, these spring bars do a superior job of helping to hold your trailer in line because of their added strength and durability.

Built-In Grease Zerks

Built-in grease zerk on the Curt weight distribution system head assembly

The system's head features 2 built-in grease zerks so that you can easily lubricate the spring bars without having to remove them from the head assembly. The grease zerks are located on each of the shafts that encase the spring bars. Simply use a grease gun (sold separately) to inject grease into each of the zerks.

Video Transcript for Curt Weight Distribution - WD Only - C17050 Review

Today, we're going to be taking a look at the Curt Round Bar MV Weight Distribution System. This unit's going to help evenly distribute weight over the axles of your tow vehicle and your trailer. It's going to offer improved stability and control. Ultimately, a weight distribution system's going to create a more level ride for both the tow vehicle and your trailer. Now, this one's going to feature a round bar system. These are constructed of solid forged steel for strength and durability. The forged steel construction's going to do a great job at always trying to keep the trailer in line.

Then, if you ever need to adjust your spring bar tension, you can do so by switching the links here on the lift chains. You can also tilt the head assembly. The desired tilt is going to be achieved by using a traditional washer design and set bolt. This is going to be your spacer rivet. It comes with all the washers that you need. That spacer rivet would install between the front face here of the adjustable shank and the backside of the head assembly.

Then, you can simply add or remove washers from that rivet to tilt the head up or down for your application. Then, you can adjust the angle set bolt as necessarily to kind of lock in that position that works best for your application. The head assembly will accept a sway control attachment ball on either side, so it's built to accept it on either side. Sway control systems are recommended. They are sold separately, and they're available here at Now, this round bar system here at the head assembly, on each side, you'll see a grease zerks fitting. That's going to allow for simple maintenance.

That way, you can attach your grease gun, pump in your grease to lubricate the upper portion of the round spring bar, making sure it operates seamlessly, and it has really nice, smooth operation for a long time. Now, the unit's going to be constructed of a steel construction, and it's going to feature a carbide powder-coated finish on it. It's going to do a great job at resisting rust and corrosion. It also comes with a snap-up lever that's going to ease hookup by reducing the lifting required by the trailer jack. It goes over that portion there, and that helps get those lift brackets up into place, which are attached to the spring bars. Now, the lift brackets are designed to basically clamp onto the trailer frame with the included hardware. It'll fit trailer frames up to 3 inches wide, and the length measurement is about 5 inches, so it's going to take up about 5 inches along the trailer frame, and they're a really nice low-profile design that helps avoid interference with frame-mounted accessories such as battery boxes, gas tanks, tool boxes, or generators. As you'll see here on the ball platform or on the head assembly, it does not come with a hitch ball.

Hitch balls are sold separately. The diameter of that hole's going to be around 1 1/4 inch, so it will accept 1 1/4 inch diameter shank on your hitch ball, but it also does come with a reducer sleeve for hitch balls with the 1 inch diameter shank. Again, your hitch ball's sold separately. It comes with a tongue weight capacity. We're looking at 500 to 600 pounds, with a maximum gross towing weight capacity of 6000 pounds. It does come with your adjustable shank. This is designed for a 2 inch by 2 inch trailer hitch receivers that are rated for use with a weight distribution system. It's also going to come with your standard 5/8 inch pin and clip, to get that shank secured inside your hitch. The adjustable shank is going to feature 6 adjustment holes. That way, you can move that head assembly up or down as needed, depending on your application. With the head assembly at the highest setting, with the shank in the rise position, it's going to give you a maximum rise of around 7 inches. With it installed in the drop position, with the head assembly at the lowest setting, it's going to give you a maximum drop of around 2 1/2 inches. Then, those adjustment holes are separated along that shank, on center, by 1 1/4 inch. Really nice design. Again, all the hardware that you need to get the unit installed is included, no-drill, clamp-on brackets. It's also going to come with a detailed owner's manual that's going to help walk you through the initial setup step-by-step. That's going to do it for today's look at the Curt Round Bar MV Weight Distribution System.

Put this on our 2006 Nissan Frontier to pull our camper. Worked great, and really helped raise the trailer tongue. 612337

This hitch seems very well made and is not difficult to assemble. I’m overall happy with this product except for the chains on the bars isn’t long enough to hook up while using this with a pole tongue adapter. 506146


The Pole tongue adapter you purchased is designed for trailer frames up to 6 inches tall. If the chains arent long enough, lower the weight distribution head by 1-2 sets of holes and tilt the head more toward the front of the vehicle. This will bring the ends of the spring bars higher, and should allow your existing chains to work.

I installed the hitch today, with the information provided on the etrailer website I was able to get the right one for my application first time around. It turned out just like I wanted. etrailer has name brand products at good prices. I'll be back. 483278

Good fit and finish of the weight distribution system. Assembled and installed easily in 1 to 2 hours. Seems to be the perfect fit for my trailer and tow vehicle. Way better value than the $900 system that the RV dealer tried to insist that I needed. 520433

- C17050

So far I have installed the Weight Distribution Hitch, very easy to install it (saved me 200 $), easier if you have a helper, took me about an hour (with a helper) to put it together, instructions very easy to follow. Solid construction, you will need tools that usually are not in every house (1" wrench) 484276

Do you have a question about this Weight Distribution?

  • Recommended Weight Distribution System for 2013 Forest River R-Pod 177
  • A weight distribution system is a good idea anytime there is a noticeable drop on the rear suspension of your vehicle. It is also a good idea if you are experiencing any sway to help minimize that trailer wander with wind gusts and passing traffic. Your 245 lb dry tongue weight along with 36 gallon fresh water tank will double that weight. The Curt MV Weight Distribution System # C17050 you referenced will help with the distribution and reduce sag but will not help at all with...

  • Husky Spring Bars Compatibility with Trailer Hitch Weight of 476 lbs
  • The Replacement Spring Bar for Husky Towing Round Bar Weight Distribution Hitches - Qty 1 # HT31521 are designed for trailers with a total tongue weight (loaded trailer tongue weight along with any cargo behind the rear axle of your tow vehicle) between 801 and 1200 lbs. These bars will be far too strong for your trailer and could cause a rough ride and even some wheel bounce. I definitely do not recommend them for your trailer. My recommendation is to use a system more suited for...

  • How Long are Curt Round Bar Spring Bars
  • I spoke with Curt and spring bars of the WD system # C17150 has an overall length of 30-5/8 inches and the diameter is 1-1/4 inches where it fits into the head. The length is measured from the center of the end that fits in the head to the center point between the holes of the small u-bolt that chain attaches to. So what you can do hopefully is install a set of bolt on brackets like the part # C17005 to the frame where the spring bars need to be which allows you to bypass the interference...

  • Weight Distribution for a 2018 Toyota Tacoma and R-Pod Trailer
  • The manual for the 2018 Toyota Tacoma mentions needing weight distribution if the trailer weighs over 5,000 pounds so I would concur that the factory hitch is rated for weight distribution. There may be a sticker on the hitch that lists a separate capacity when using weight distribution. Curt MV Weight Distribution System # C17050 maxes out at 600 pounds tongue weight so you will actually want a system rated higher. Also when calculating tongue weight capacity for weight distribution...

  • Recommended Weight Distribution System for 2018 Coleman 2305QB Travel Trailer
  • When looking for a properly rated weight distribution system, the most important factor to consider is the total tongue weight of your setup. This will include both the loaded tongue weight of your trailer (as if ready for a trip), along with any added cargo weight behind the rear axle of your Silverado. Ideally, this number will fall somewhere near the middle of the operating range for the system you choose. Most likely, the 501 tongue weight that you referenced in your question is...

  • Reese Pole Tongue Adapter Compatibility with Curt Weight Distribution System
  • The Reese Pole-Tongue Adapter for Weight Distribution Systems - 7,500 lbs GTW, 750 lbs TW # RP3280 will work well with the Curt MV Weight Distribution System - Round Bar - 6,000 lbs GTW, 600 lbs TW # C17050. You will just need to add a hitch ball like # 40038 for a 2 inch diameter or # C40030 for a 2-5/16 inch option. If your trailer is aluminum, you will want to check with the manufacturer before using a weight distribution system.

  • How to Choose the Correct Curt MV Weight Distribution System for a 2015 Nissan Pathfinder
  • The Curt MV Weight Distribution System part # C17050 could very well be correct for your utility trailer. However, in order to confirm this we would need to estimate your total tongue weight which is the loaded ready to tow tongue weight of the trailer in addition to the weight of any cargo stored behind the rear axle of the tow vehicle. A good rule of thumb is that the tongue weight of the trailer will be around 10-15% of its gross vehicle weight rating (GVWR). If the above figure...

  • Does Curt MV Weight Distribution System C17050 Work Over a Range of Trailer Tongue Weight
  • Weight distribution systems like the Curt MV Weight Distribution System # C17050 are specified to work over a range of trailer tongue weights (TW). This system is rated for TW from 500 to 600-lbs. Ideally the total TW of the trailer/vehicle system will fall right near the middle of a WD system's operating range. This Curt system would then be ideal for a total TW of 550-575-lbs. The total TW of a trailer/vehicle system is the sum of the actual fully-loaded trailer's TW plus the weight...

  • Weight Distribution Recommendation for a 3500 lb. Boat Trailer and 2015 Jeep Wrangler
  • The Curt weight distribution system # C17050 is designed for a tongue weight range of 500 to 600 pounds. If your trailer's tongue weight maxes out at 325 this system is too heavy for the trailer but no worries because there are other options that will work great with your trailer. First, you mentioned that the trailer is a boat trailer. If it has a straight pole tongue instead of an A-frame you will need to have a pole tongue adapter.

  • Compatibility of a Chain-Hanger Style Weight Distribution System with a Surge Brake Actuator
  • Some chain-style Weight Distribution (WD) systems have been rated by their manufacturers to be used with a surge brake actuator while others have not. Curt is one of the manufacturers that says some of their WD systems, like part # C17050 that you referenced, are okay for this purpose. Since this isn't something that is consistent among all manufacturers I recommend staying away from this kind of system. Instead I recommend using a system like the Fastway e2 Weight Distribution # FA92-00-0600....
