Video Transcript for Curt Pin and Clip Review

Hello neighbors, it's Brad here at etrailer and today we're taking a look at the Curt 5/8ths pin and clip. Now this is gonna be for your two inch hitches and it's gonna allow you to hook your accessories into your hitch. Most of your ball mounts when you pick them up will not come with a pin and clip and a lot of accessories will have their own. But if you're getting something secondhand or yours doesn't you are gonna need a pin and clip to have any accessories stay in place. So a pin and clip is obviously very crucial when using your hitch. So getting one that's nice, like this is a great option.

And what makes it nice is some of the other ones just have a hole drilled through and once you put your pin in, you're kind of stuck with a little bit of rotation before it hits the safety chain loops where this one's different. It has a nice groove allowing you to put your pin and clip in in any direction and that way it's also not gonna just bind up against the safety cables. You can kind of move this around if you need a little bit of extra room. Now you also have a two and three quarter inch usable span here. So on our hitch we do have a little bit of room so if you have any other accessories that might go on here that's gonna allow for that.

Now being that it is made out of steel that means it's gonna be durable but it also has a zinc coating on here. So if you plan on leaving your accessories or your ball mount in place throughout the year, no problem. This is gonna hold up to that rust and corrosion in whatever elements you may be driving. Now if you are leaving your accessories on the vehicle throughout the year, I would maybe consider looking at a locking pin and clip. Kurt has plenty of options here available at etrailer and that way you can leave your accessories on, lock it in place and not have to worry about someone taking your accessories.

And that was a look at the Kurt 5/8ths pin and clip for two inch hitches.

Average Customer Rating:  4.7 out of 5 stars   (109 Customer Reviews)

This grooved, 5/8" diameter pin fits 2" square receiver hitches. Includes retaining clip. Zinc finish resists corrosion.

by:

Pretty simple device. Seems as durable as the other hitch pins that I use.



by:

This pin fits and seems strong, but I don't love the design. The clip sticks out which makes it potentially exposed to something like road debris which could catch it and pull it out, thus exposing the pin to risk of a major failure. I ordered a different pin with a better design.



by:

Nice pin for my new receiver. Perfect fit, and secure. Recommended.



by:

Just what I needed and it works fine. Thank you.



by:

I needed a longer receiver for my bass boats so that when turning on the boat ramp, the bass boat steps i boat would hit my bumber. The person how helped me took his time and found the products I needed. Everything was great heavy duty, perfect!!!!! Gone fishing



by:

Everything was perfect with etrailer!!!!



by:

Got what I was looking for, after a bit of a wait, no fault of e-trailer. Customer service was great, Ashley called me and got my order sent out with a $30.00 savings. Thanks Ashley!



by:

This 8" Drop Ball Mount was exactly what I needed for my Honda Pilot to transition to my Camper and utility trailer. This kept both my units level for proper towing. The ball mount, ball, and pin will hold up for years of towing. I am grateful for etrailer and everything they have to offer. They will always be my go to store for my towing needs.



by:

I have used the reducer and pin twice to carry 2 bikes on a Kuat rack over a total of 800 miles without problem. I did find it cut down on the movement if I put a couple of pennies on one side where that was some slack between the receiver and the reducer (which is the step down from the 2 to 1 1/4). Overall, well pleased.



by:

We received the items and they were exactly what we ordered.
My husband put the receiver on our RAV 4 we other ease.

  • Do You Carry Front Receiver Hitches for My 2015 Mercedes-Bens Sprinter 3500?
    I have a solution for you. Unfortunately, we do not carry a front-mounted hitch option for your 2015 Mercedes Sprinter 3500. With that being said, your best bet is to use a rear hitch receiver like the Curt Trailer Hitch Receiver # C13388 (for 144 and 177 inch wheelbases with the standard bumper) or the Draw-Tite Max-Frame Trailer Hitch Receiver # 75601 (for 144 and 177 inch wheelbases with the factory step bumper). Both of these hitches come with plenty of tongue weight capacity to...

  • Dimension of Pin Hole on Curt Class III Hitch Receiver
    Good news, I can help you figure out which hitch pin you will need for your Curt Hitch # 13160. The # C21504 is the recommended hitch pin for your 2 inch Curt Class III Hitch. The pin measures 5/8 inches wide, and the diameter of the hole on the hitch is 5/8 inches as well. If you would like to get a locking hitch pin to secure the item you are transporting from theft, I would recommend the etrailer # e98882.

  • Dimension of Lower Leg on Viking Solutions SwiveLift
    These lifts are not in stock at this moment otherwise I would go measure this for you. Our best estimate is that the portion of the vertical tube below the 2" horizontal tube measures between 4 to 7 inches. If you are asking about the platform - it does not have to be lower all the way down. I have attached a picture illustrating this. You will also need a hitch pin and clip to attach this to your receiver. You can use the etrailer # C21504 zinc coated pin.

  • Recommended Anti-Rattle Hitch Lock for 2-Inch Class III Hitch
    There are more secure options than a standard hitch pin and clip like # C21504 for securing a ball mount or other accessory in a 2-inch hitch. I can offer you options for both stabilizing the installed item and for locking it for theft deterrence. So long as the ball mount is a hollow type like # C45036 you can use Let's Go Aero part # 63232 to both stop play and rattle in the hitch and to lock the ball mount, or any other hollow-shank item such as a bike rack like # S64400.

  • Recommended Snow Plow for a GMC Sierra 2500 w/ a Front Mounted Hitch
    Since you already have a front mount hitch on your 2022 GMC Sierra 2500 then the Detail K2 Elite Snowplow item # K2AVAL8826ELT will work great for your truck. The Detail K2 Elite item # K2AVAL8826ELT weighs 296 lbs and requires a 2" x 2" receiver. Most front mounted hitches have a minimum capacity of 500 lbs so you are good to go. It has a wireless remote so you can control the blade height from inside the cab and there are skid shoes so you can plow over uneven surfaces like gravel...

  • What Front Hitch and Snow Plow Fits My 1997 Dodge Ram 2500?
    Yes! The Curt Front Mount Trailer Hitch Receiver - Custom Fit - 2" # 31604 is confirmed to fit your 1997 Dodge Ram 2500 4x4 with the Cummins engine. The hitch comes with all mounting hardware included. Also, you will be able to attach the Detail K2 Elite Snowplow for 2" Hitches - 88" Wide x 26" Tall # K2AVAL8826ELT to that setup. If you need a hitch pin for the plow to attach to the hitch, I recommend the # C21504.

  • Compatibility Of Towing Components For 2003 Chevrolet Tahoe
    The Curt Heavy Duty Forged Ball Mount, part # C45342 will work well with the Curt Trailer Hitch, part # C15324 on your 2003 Chevrolet Tahoe. This is a Class V hitch and it has a 2 inch receiver opening. The # C15324 is designed to fit 2 inch receiver openings and features a 5 inch rise or 6 inch drop. The ball mount uses a hitch ball with a shank that measures 1-1/4 inches like part # A-90 you mentioned. The # A-90 is a 2 inch hitch ball and has a 2-5/8 inch long shank. The Curt Pin And...

  • Availability of Just Ball Mount of Curt Ball Mount # C45036
    Yes, for just the ball mount portion of the part # C45036 you'd want the part # C45312 instead. This doesn't come with the pin and clip # C21504. If you want the smaller 1-7/8 inch ball kit use # C45034 or # C45041 for the 2-5/16 inch.

  • What Do You Recommend for Transporting My Vespa GTV 300 on My 2004 Lexus RX 330?
    I have an answer for you. As far as the aluminum MaxxTow carrier, I assume you mean the MaxxTow MaxxHaul Aluminum Motorcycle Carrier MT70101. I noticed that you discovered that your vehicle has a maximum tow rating of 3500 pounds. However, what we need to know is the maximum tongue weight rating of your 2004 Lexus RX 330. From my research, I discovered that the maximum tongue weight is 400 pounds. In order to confirm this rating, I recommend consulting with your owner's manual. With that...
