Video Transcript for Curt Hitch Ball - Gooseneck Hitch Ball - C60603 Review

Today we're going to review part number C60603. This is the Curt one inch high rise ball for Curt double lock flip and store goose neck trailer hitches. Now this ball will provide an additional one inch rise to add clearance for trucks that use plastic or rubber bed liners. This is designed to fit the Curt double lock flip and store goose neck hitches. Right here you can see where the pins go. The double locking pins give you extra security for the trailer ball. The diameter of the ball is your standard goose neck sized two and five sixteenths diameter. It'll couple to most goose neck trailer.

The shank diameter right down here is going to measure right at two and three quarter inches. It has a weight capacity of thirty thousand pounds, and that is stamped on top of the ball. It does have an extra one inch additional rise here to clear those bed liners. Basically if you put a ruler on it. Now the standard ball that comes with that hitch has about a three quarter inch section rise, so this one will have actually one in three quarters in Jiffy Newton measure from here up to here.

It's going to measure one and three quarters, and that's because the standard ball, again has the three quarter inch. This will give you an additional one inch rise to the ball. That should do it for the review on part number C60603. The Curt one inch high rise ball for Curt double lock flip and store goose neck trailer hitch. .

1" High-Rise Ball for Curt Double Lock, Flip and Store Gooseneck Trailer Hitch - C60603

Average Customer Rating:  4.8 out of 5 stars   (694 Customer Reviews)

Designed for use with Curt's Double Lock, Flip and Store gooseneck hitch, this ball provides an additional 1" of height to fit your application.


The ball works great, but I am not able to flip it over so it can sit flush in the bed because there is no groove on the shaft for the upside down position. I am disappointed with that aspect of the design.

This ball is not intended on being flipped over and stored in the hitch as it is a high-rise. This other one can be stored but will not work for you if you need the additional length: item # C60616.


Exactly what I needed


Arrived on time. Exact fit


It went right in to the hole fix excellent





Perfect, just what I expected. Fast shi pping.


Package arrived earlier than expected and we were able to get started hopefully to beat the next rain storm



Quick and excellent sale.


My poor rating is all about the product and no reflection on etrailer - As others have commented this hitch ball needs to be made available in Stainless Steel. It has, so far, functioned as advertised and fits my requirements. However, the material and finish are poor. I use this to tow a 2000lb GVWR trailer (Hélio O2). I routinely clean and grease my hitch coupler and this hitch ball. In the short time and relatively few miles I've used this the finish and base material are wearing away rapidly (see attached pictures taken at time of this review).
Also, to be nit-picky: It does not make sense why the 2" Rise (Item # C40034) is priced less than the 1" rise (Item # C40033).


I just opened up my new Class 5 Curt XD hitch and have not yet installed it so my comments are based on first impressions only. It is very heavy duty - and heavy at 40 lbs. - made of extremely thick metal and outfitted with quality Grade 8 bolts with square necks so they won’t turn when torquing on the nuts to attach the main tube to the side mounting plates. My bolts are plated yellow (which I like) rather than silver as you may have seen in some online photographs. It is substantially beefier than my existing Grade 4 hitch and superior in every way. It’s an impressive piece of hardware. I cannot imagine anyone being disappointed with it on specifications, quality, strength, and general appearance. It’s a beast. What I AM disappointed in is Curt’s packaging and the condition in which the hitch arrived. (This is NOT a reflection on as the hitch arrived in Curt’s original packaging.) The unassembled main tube and the two side mounting plates come bundled together with nothing separating them but shrink wrap. No cardboard, plastic, even paper coming between the metal surfaces - just shrinkwrap probably not even a couple of mils thick. With basically metal-to-metal contact in an oversized-box with the bundle jostling around, it would be a miracle if there were no scratches, gouges, or some type of damage to at least one piece, which is exactly what happened to my hitch. The main hitch tube, on the exterior facing plane, on the driver side where I’ll see it every day, has some gouges on it that go through the powder-coating to bare metal. I can - and will - paint them to prevent rust (and, therefore, have to paint the whole hitch to match). But the gouges will still be noticeable as they go through the thicker, pebbly, powder-coat finish and will undoubtedly still appear as depressions in the surface even once painted. I fully realize this kind of surface damage will almost certainly happen with regular usage of the hitch anyway and that it’s certifiable to demand absolute perfection in anything. But if you are someone who cares about the aesthetics of your equipment and keeping it looking new for as long as possible, it is very disappointing to receive such an expensive and prominent piece of hardware damaged right out of the box and requiring immediate repainting. The plastic parts bag had also ripped open in transit, with nuts, bolts, shims, etc. rattling around in the box. I am dumbfounded that Curt packages such a high-quality piece of equipment so shoddily where such damage is virtually unavoidable. I bought from Curt solely due to their being an American manufacturer and to support American workers so this is doubly discouraging. It’s a trivial complaint in the big scheme of things and not worth demanding a replacement over. Just be aware that unless Curt changes their packaging practices it is very possible you will have the wind taken out of your towing project sails just as I have. Again, this in no way reflects on etrailer. My experience to date with etrailer (website, educational resources, staff reviews, ordering, tracking, email contact, etc.) has been beyond exemplary in every way. They rank as a Top Five online retailer in my opinion, maybe even the best.


Hitch Ball worked out great getting my trailer at the right level position.


I would use the company again. UPS lost the product i purchased, and etrailer called me to offer to replace it at no additional charge. I work for a large corporation and the professional speed, and the way they handled the issue was great.


Needed an extended ball mount for my new Jeep in order for the utility trailer tongue to clear the spare tire. Item is exactly as described on site and arrived earlier than expected.
etrailer has always given me great customer service. It is my go to place for all towing and trailer needs.


Excellent tow ball. Solved the problem that the original towing hitch was to low for our tandem boat trailer.
Has been used extensively over the last year towing our boat without any issues.
Highly recommended. were excellent to deal with.


A great deal. Well used with my new 14k dump trailer and working great!


etrailer is great they have what I need and are fast to ship


This is one massive hitch ball. Just one look and you know it is strong. I also love the little extra height. A great fit for my 2 5/16 coupler.


The 1” rise gave me the perfect height to level my trailer that was not possible with any combination of receivers and balls. I tow an enclosed cargo trailer 10,000 miles per year, some of it on gravel or minimally maintained roads. If the load is not level, the cargo tends to migrate forward or aft, no matter wow well it is secured. This can make the load dangerously balanced. This ball makes possible perfectly matched height between my truck and trailer. I really wanted to give this item the perfect five star rating. The only flaw is how easy it has rusted. It does not affect its function, but too easily rusted is a flaw (in my opinion). Otherwise, I wholeheartedly recommend this product.


Dimensions are correct, photo is not. Photo is not a chromed ball; description is correct, it is chrome. After a couple of trips with a 6K# trailer, chrome is still in good condition, no peeling away (I did grease before attaching.). Nut fits a 1-13/16 wrench.


This was exactly what I needed and it was shipped very fast. Great service.


I like the extra meat this ball has. It also enabled me to get the running hieght "just right" for the towing application I use it with.


Exactly was I was looking for...I am going cross country on a motorcycle trip and I am pulling a trailer for gear and supplies. This riser puts my trailer at level while attached to my bike. Delivered on time, great solid product.


Can't go wrong dealing with these folks. Quick response and shipping. Would buy from again and recommend to all.


I needed a little more height for my hitch to clear the shackle on my Kobota tractor. This high rise ball was just the ticket. Thanks etrailer for another quality product!


Was just what I needed to get the trailer tongue away from my weight distribution hitch. Previous ball was too low, allowing the trailer tongue to impact my hitch!

  • Hitch Ball Falls Through Hole on Curt Double Lock Gooseneck Hitch When Released
    On the Curt Double Lock, Flip and Store Underbed Gooseneck Hitch like part # C60720, there is a 3/8" guide pin in the lower portion of the receiver tube opening. This guide pin is designed to hold the hitch ball in place when the handle is pulled so it does not fall through the hole. If your hitch ball falls through this hole when the handle is pulled then this pin has sheared off. This usually happens when weight is placed on the hitch ball without the dual locking pins fully engaged....

  • Dimensions of Curt Gooseneck Balls C60616 and C60603
    Your Curt Gooseneck Hitch # C60723 should have shipped with standard gooseneck ball # C60616. The High-Rise Ball is part # C60603. I measured both hitch balls in our warehouse; their tip to tip lengths are 8-3/4-inches for standard ball # C60616 and 9-1/2-inches for High-Rise Ball # C60603. I spoke to one of our tech contacts at Curt and he reviewed their engineering drawing for the hitch installation on your 1993 F-250 with overload springs. Their documentation showed no stabilizer bar...

  • Replacement Gooseneck Round Hitch Ball for 2004 Dodge Ram Truck
    Based on the Curt 1" High-Rise Ball for Curt Double Lock, Flip and Store Gooseneck Trailer Hitch # C60603 you asked from, I'm assuming you have a gooseneck hitch and need a replacement hitch ball. Obviously you don't have a B&W hitch because you asked for a round ball option versus the square shank so we can at least slightly narrow it down for your 2004 Dodge Ram. We have both Curt and Draw-Tite hitch options for you Ram, so I'll give you the part numbers for the hitch and then the...
