This hitch is extra super heavy duty!!! The receiver shaft is literally SOLID steel and weighs so much more than any other ball mount I've owned, because they've all been hollow. I can believe it is rated to tow 17,000lbs with the 2-5/16" ball!! 598839

I ordered the wrong ball mount the day before Christmas. I waited until the day after Christmas to try to change my order. To my surprise my order was easily straitened out and three days later I got the correct ball mount. I would order more trailer accesseries from etrailer again. 736105

We’ve already installed it and hitched up the horse trailer. Works great for my needs. Half the weight of the much heavier weight distribution system we had been using (and will continue to use for Interstate travel). Hook up was fast and easy. 734978

Ask the Experts about this Curt Trailer Hitch Ball Mount

  • Ball Mount Recommendation for Towing Coachmen RV
    You'd need a drop of right at 1 inch to tow the trailer you mentioned level based on the dimensions you listed. The closest to that is a 2 inch drop ball mount like the part # C45331 which fits a 2 inch hitch like you have as well. It has a towing capacity of 15,000 lbs and comes with a 2-5/16 inch hitch ball as well. This comes with a pin and clip as well. Since there isn't a 1 inch drop ball mount and this is very close it will work well.

  • Can the Curt Heavy Duty Forged Ball Mount Be Used With Friction Sway Control
    In order to use the Curt Heavy Duty Forged Ball Mount part # C45331 with a friction sway control device you'd need to have a sway control tab welded to the side of the platform such as the Weld-On Sway Control Tab part # C45822. If you don't already have a sway bar you can use the Curt Friction Sway Control part # 17200.

  • Can Curt Forged Ball Mount Be Flipped For More Height When Towing Car Trailer
    I called my contact at Curt and they told me that you can use the Curt Heavy Duty Forged Ball Mount, part # C45331 flipped over if you wish but you will probably have a heck of a time removing the ball. They said the ball is machine-torqued at 450 ft-lbs when it is attached to the drawbar. An option that may be easier on you would be to use a different ball mount and ball. The ball mount I recommend is part # 40330. This ball mount has a 1 inch rise or 2 inch drop and a weight capacity...

  • Size of Wrench/Socket for Nut on Hitch Ball of Curt Ball Mount # C45331
    The size of wrench or socket needed tighten or loosen the nut of the ball mount # C45331 is 1-7/8 inch. It's on there with quite a bit of torque as the rating for the nut is 450 ft lbs of torque.

  • How To Choose Ball Mount for Class II 2 Trailer Hitch Receiver
    In regards to trailer hitches, class I and II will have a 1-1/4" receiver tube opening and class III and IV will have a 2" receiver tube opening. I have never heard of a class II with 2" receiver tube opening but I would not get too caught up in the class ratings. If you have a 2" receiver tube opening then the Curt Heavy Duty Forged Ball Mount part # C45331 will work just fine. That said, you need to abide by the weight capacities listed on the hitch, not the ball mount. Please note,...

  • Does Curt Heavy Duty Forged Ball Mount # C45331 have Ball Torqued Down in Drop Position
    The Curt Heavy Duty Forged Ball Mount # C45331 that you referenced comes with the hitch ball pre-torqued in the drop position so it's ready to be used as soon as you receive it.

  • Solution for Needing Curt Ball Mount and Hitch Ball in 1 inch Drop Position Over 1 inch Rise
    Since we do not have a version of the # C45331 with the setup in the rise position instead of the drop position your best option would be to remove the ball and reinstall it in the rise position or go with the part # C45340 and # C40008 which you could then attach to the ball mount in the rise position. The demand for ball mounts in the drop position is much more than in the rise position as tow vehicles generally are getting taller and taller while trailers mainly are staying same height....

  • 2 inch Ball for Curt Ball Mount # C45331
    Since the Curt ball mount part # C45331 has a 1-1/4 inch diameter ball hole you'd want a hitch ball like the part # A-90 which will fit and work great.

  • Trailer Hitch with Higher Capacity than Factory Hitch on a 2018 Ford F-150
    With your existing hitch on your 2018 Ford F-150 the maximum weight you can tow, even when using weight distribution, is that 9,100 pounds you quoted. If you were to install an aftermarket one such as # C14016 then you would still be limited to 9,100 pounds but would not have to use weight distribution to reach that capacity. So what it comes down to is whether or not you want to use weight distribution. Since you have 2 trailers you may not want to move the system back and forth between...

  • Can the Ball Mount # C45340 be Ordered with the Curt Hitch Ball # C40008 Already Installed
    I do have a solution for you, but we do not install parts like the Curt Heavy Duty Forged Ball Mount # C45340 and 2-5/16" Hitch Ball # C40008 before shipping them out. Any ball mounts that come with a hitch ball installed come like that directly from the manufacturer. If you do not need the full 17,000 lb capacity of the ball mount # C45340 that you referenced then you can use the Curt Heavy Duty Forged Ball Mount # C45331 which is essentially the same exact ball mount with a 2-5/16"...

  • Ball Mount for 2 inch Hitch that has 2 inch Drop and 15k Total Weight Capacity
    Ball mounts with 1 inch diameter ball holes will have lower capacities like the Draw Tite part # 2923 which has a 1 inch ball hole size but only has a capacity of 7,500 lb. Only similar ball mount we have is the Curt Heavy Duty ball mount part # C45331 which as the same 2 inch drop like you need and a capacity of 15,000 lbs. It comes with a hitch ball mounted to it already which measures 2-5/16 inch. This would be your best option.

  • Recommended Locking Hitch Pin for Curt Heavy Duty Ball Mount C45331
    For a locking hitch pin to secure your Curt Heavy Duty Forged Ball Mount # C45331 to your trailer hitch, I recommend the Trailer Hitch Receiver Lock # e98882. This is a great stainless steel lock designed for 2 inch trailer hitches. It features a pick-proof screw-and-lock design that will prevent theft of your ball mount or other hitch-mounted accessory. Keep in mind that this will work with 2 inch trailer hitches that have an outside width of up to 2-5/8 inches. If your trailer hitch...

  • Hitch, Brake Controller and Wiring for Towing with 1995 Chevrolet Suburban 4X4 K2500 7.4L
    We do not have a single kit/product with all the towing components you'll need to tow a trailer with brakes with your 1995 Chevrolet Suburban 4X4 K2500 with 7.4L engine but we can still get you all set.

  • Comparing B&W Heavy-Duty Ball Mount to Curt Heavy Duty Ball Mount
    The BandW Heavy-Duty Ball Mount - 1 Rise, 2 - 8-1/2 Long - 16,000 lbs # BWBMHD30010 is very similar tot he Curt Heavy Duty Forged Ball Mount with 2-5/16" Ball - 1" Rise, 2" Drop - 15,000 lbs # C45331 which has the same hitch ball shank dimension of 1-1/4 inches as well as the same rise and drop. Another benefit is the hitch ball is already installed and torqued to spec. Both are quality ball mounts with the B&W having a slightly higher rated capacity. Stock levels change constantly...
