The product is great. However Etrailer sent me 2 different length spring bars labeled the same. I called customer service and they agreed to fix the issue. However, it took them 5 more days to even get them in the mail. Maybe I'll get them in another week. This is the first time etrailer really dropped the ball. Screwing up the order was one thing, taking another week before shipping the replacement Is too much.

Spring bars work as advertised.



by:

My old weight distribution system was undersized for my new camper, but otherwise everything was good. I contacted etrailer about sizing up just the trunion bars. They contacted Curt and confirmed that was possible, then added this part to the catalog, all within 36 hours of my e-mailing my request. The parts arrived in great shape and I'm anxious to try them out.

Well, while the product was what I requested, it did not fix my slight sway issue. Ive since upgraded my tow vehicle and hitch system with a weight distribution hitch with built-in dual anti-sway control.



by:

Product came as promised and as a replacement part it fit perfectly.



by:

what i was looking for, price was right



by:

Needed an upgrade from my 550 Trunnion springs to 1000 lbs. perfect fit. At half the price of local dealers. Others wanted to sell me an entire new towing system for four times the amount. Thanks for a a name brand product (Curt) at a great price.



by:

  • 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 etrailer scale # e99044. 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...

    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.
