Video Transcript for Curt Weight Distribution C17307 Review

Speaker 1: Today we're taking a look at the CURT Replacement Weight Distribution Head for trunnion style bars. Now this fits CURT trunnion style weight distribution systems, part numbers 17300, 17301, 17302, C17330, C17331 and C17332. The unit is made from a solid steel construction. It's very strong, very durable, has a nice powder coated finish on it to resist rust and corrosion, and lasts a long time.The unit is adjustable when paired with a shank that has multiple adjustment holes. The bars fit into the connection points right here. It does have the attachment point on either side for a sway control system, and the last thing I want to mention really is the ball hole diameter, measuring this right here, so this will accept a hitch ball with a shank diameter of up to an inch and a quarter, so this is designed for a hitch ball with a shank that has a diameter of an inch and a quarter on it.

Mounting hardware not included.That's going to do it for today's look at the CURT Replacement Weight Distribution Head.

I received this part for my Curt model 17302 hitch and installed it finding it to fit as expected. The reason that I replaced this part is that the original part was damaged due to an accident. I am a satisfied customer!

  • Adding a Second Weight Distribution Head and Shank for a Fastway Weight Distribution System
    Yes, we do have a head only that will work great for you. It is the replacement Fastway e2 head # FA92-02-1255 for 6K to 12K rated systems or # FA92-02-0410 for the 4.5K system. This head is the exact same as the ones that come in the full kits. You would have to use a Fastway head in order to use the Fastway spring bars. Another brand head will not work. You will also need replacement hardware kit # FA92-02-9600 since the above heads do not include this hardware. For a second shank...

  • How Can I Tell the Brand of My Weight Distribution Hitch Head
    Usually there is a sticker under the ball platform part of a weight distribution head with information on it but on yours I do not see that. It looks like a Curt head though an older one, similar to what is on the discontinued number 17300. Although there have been some Equal-I-Zer brand systems that look almost identical.

  • Can a CURT Weight Distribution Head be Used with Spring Bars from Other Brands
    The CURT Replacement Weight Distribution Head, # C17307, will only work with CURT trunnion bars. The same goes for Valley, and Reese weight distribution heads. Each can only be used with parts from the same manufacturer. If you decide to go with a whole new system, the most economical system we have for tongue weights ranging from 600 to 1,200 pounds is the Reese Weight Distribution Kit, # RP66542. The only other part you would need is a properly sized ball, # 19286 (2-5/16 inch diameter)...

  • Curt Weight Distribution Trunnion Bar Compatibility with Head Assembly C17307
    Weight distribution/sway control (WD/SC) spring bars can often be changed out for new bars with a different weight capacity but it is never a good idea to mix components from different systems or manufacturers as they aren't designed to be compatible at all. With the Curt trunnion style head assembly # C17307 you could use a spring bar like # C17308 for trailer tongue weight (TW) up to 800-lbs. Please feel free to let me know your trailer TW.

  • What Does the Flip Up Part of the Curt Weight Distribution Head # C17307 Do?
    The Curt Replacement Weight Distribution Head for Trunnion Style Bars # C17307 is the only system like this that Curt has. Those are spring loaded clips that keep the trunnion bars in place. If you want a different style of trunnion bar head, Curt has moved more to the TruTrack version like # C17509, # C17507, or # C17506 depending on the weight capacity of your system. Most systems have another attachment method, so if your system doesn't have them, it is not an issue.

  • Capacity of Curt C17307 Replacement Weight Distribution Hitch Head
    The Curt # C17307 weight distribution head is good for up to 10,000 gross trailer weight/1000 lbs tongue weight. The head is compatible with Curt trunnion style weight distribution systems like # 17302, # C17330 or # C17332.

  • Can Curt Weight Distribution Head C17307 Fit Equal-i-zer Shank
    Yes the Curt weight distribution head part # C17307 is compatible with the shank part # EQ90-02-4600 that you also referenced. These two parts together would give you a really long ball mount setup with an adjustable height. You'd also need the hardware kit part # C17350 as well to bolt the head to the shank.

  • Curt Weight Distribution System Trunnion Bar Removal For Storage
    The trunnion bars of the Curt Short-Arm Weight Distribution System with Sway Control - Trunnion Bar - 15K GTW, 1.5K TW # C17422 are easily removed when they are not under tension. You will simply release the clips at the top of the hitch head and then remove the top of the trunnion bar before lifting the bottom out of the head. For the visual check out the Curt Replacement Weight Distribution Head for Trunnion Style Bars # C17307 and attached videos. Even though it doesn't show the...

  • Dimensions of Curt Replacement Trunnion Bar # 17303
    The bar length is 30-5/8 inches long. The knuckle is 4-7/16 inches with each nipple being 1 inch tall by 1 inch diameter with a slight taper. I've attached a photo to assist. Hitch heads and spring bars are not normally compatible between brands. My recommendation is to use the Curt Replacement Weight Distribution Head for Trunnion Style Bars # C17307 along with the Replacement Trunnion Bar for Curt Long Trunnion Style Weight Distribution System - 1,000 lbs TW # C17303 to ensure a...

  • Spring Bar Tension is Higher on One Side of Trailer than Other Side with Curt Weight Distribution
    The tension on the spring bars fore any weight distribution system should be nearly identical (when sitting still on level ground with the trailer in a straight line behind the truck). The little bit of play making the shank off-level at the hitch is going to translate to anything else connected down the line to be off even more so that could have something to do with it. Curt does not specify a maximum or minimum amount of washers but if you are angling the head down to get the trailer...

  • Replacement Spring Bar Retainer Clips for Curt Trunnion Bar Weight Distribution System
    I do have an option for you but the Curt Bolt Kit for Trunnion Style Weight Distribution Hitch part # C17350 does not come with the spring bar retainer clips that you are referring to. Unfortunately, these retainers clips are not sold separately as they are built into the head so if the head you have now does not have these or they were damaged then you would need to replace the entire head as well with the Curt Replacement Weight Distribution Head for Trunnion Style Bars part # C17307.

  • Replacement Head and Trunnion Bar for Curt Weight Distribution System
    For a system like the Curt # C17422 you asked the question from, the Curt Replacement Weight Distribution Head for Trunnion Style Bars # C17307 is what is needed. If you want the trunnion bar as well, then you will want # C17337 if you have a 28-3/8" short bar or # C17303 if you have a 30-5/8" long bar system.

  • Can Curt Short Arm Spring Bars be Used in the Same Head as Regular Length Spring Bars
    If your Curt weight distribution system uses trunnion bar head # C17307 then yes, you can use the short arm spring bar # C17335. If your head does not look like this let me know what you do have and I can determine if there are any other options.

  • Trunnion Bar for Curt Weight Distribution Head 17307 for 7000-lb Trailer
    For a 7000-lb loaded trailer the typical tongue weight (TW) range will be 700 to 1050-bs so the trunnion bar you'll want to use with Curt weight distribution head # C17307 is part # C17303. You will need to order two since this bar is sold individually. If you want to measure your trailer TW accurately you can use the Sherline scale # 5780. Please tell me the total TW you measure and the weight of any cargo behind the rear axle of the tow vehicle, since that has to be added to the trailer...
