I purchased a trailer hitch, ball mount, pin, and wiring set for my 2006 Toyota Tacoma. They were delivered promptly and in good order. With the help of the online videos, as well as the informative written directions, I completed the installation of all items in less than an afternoon and everything fit and operated as advertised. I am very pleased with the products and the excellent service. Needless to say, I highly recommend etrailer.com. Dennis S. Minnesota 74462

I never leave reviews but felt compelled to based on my outstanding experience with your company. From the great product and installation videos on each product I bought, to the great customer service and fast shipping, I wish every online purchase went as smooth as this transaction. In terms of the cargo carrier, well built and works as advertised. You guys are awesome, keep up the good work. 411413

Thank you for such prompt service. I put this on my Polaris 570 mid size Ranger. The problem was a normal hitch was under the bed and a 2 inch rise was a bit too low for a level trailer. This fixed the problem moving the ball out further and higher. Much easier to hook up. I would recommend your company to others. 483919

Good for normal trailer hook up and towing, but when trailer hitch is not used and a trailer hitch insert is used a key locking clip and pin should be used to avoid any one stealing the insert you have inserted to replace the actual towing bracket. People have told me they had to learn the hard way on getting their College emblem stolen because they used the normal pin. 580468


Comments

If you need a locking pin I recommend part # 7683. Please keep in mind this lock will not work with double-walled hitches or some factory 2 inch trailer hitches that have an outside width wider than 2 5/8. If a longer pin length is needed, see hitch lock part # RH5-XL.

Do you have a question about this Hitch Pins and Clip?


  • How to Use the Thule T2 Bike Rack with a 2-1/2 Inch Trailer Hitch
  • You are on the right track. The only way we have that will allow you to use the Thule T2 Classic 2 Bike Platform Rack part # TH9044 with the 2.5" receiver tube opening on your truck would be with adapter. For this, I recommend the Brophy Hitch Reducer and Extender part # HR26. This adapter offers both a reducer from 2.5" to 2" and an extension of 7" from the center of each hitch pin hole. This 7" extension will have more than enough room for the shank of the T2 to securely rest inside....

  • How to Choose the Correct Ball Mount for a 2017 Subaru Forester
  • In order to choose the correct ball mount you will need to measure from the ground to the top of the inside edge on the vehicle's receiver tube opening and then compare that to the distance from the ground to the bottom of the coupler on the trailer while level. The distance between these two measurements will give you the correct amount of rise/drop you will need to look for in a ball mount. For a ball mount with a 5" rise I recommend part # C45336 and for a ball mount with a 6" rise...

  • MaxxTow Trailer Hitch Receiver Adapter - 1-1/4" (Class II) to 2" Hitch - 11" Long Item # MT70032 does not come with any hitch pins but we have numerous options for both 1/2 inch and 5/8 pins. If you want regular hitch pins the for a 1/2 inch you can use # F-4. And for a 5/8 inch you can use # C21510. For locking pins you can use # 7680 for the 1/2 inch and # 5201 for a 5/8 inch. I have linked some videos below on a few of these products for you so you can see them in action!

  • What is the Weight Rating of the Curt Pin and Clip # C21510
  • Hitch pins are not given weight ratings because they are built with such extreme weight bearing capabilities that the trailer hitch, ball mount or trailer coupler is more likely to fail than the hitch pin. Most Class IV trailer hitches have a maximum towing capacity of 12,000 lbs and a tongue weight capacity of 1,000 lbs. Before you tow your horse trailer, you will also want to verify the towing capacity of your tow vehicle. There are instances where a Class IV hitch is available for...

  • Recommended Trailer Hitch Pin for a Class III Trailer Hitch with 2 Inch Receiver
  • The Curt Trailer Hitch, # 13514, is a Class III trailer hitch with a 2 inch receiver so you will need a 5/8 inch diameter pin just like you suggested. For a standard pin and clip, we have # PC3 or # C21510. For a locking pin we have the Trailer Hitch Receiver Lock, # 7683.

  • Bolt Hole Measurements of the Curt Trailer Hitch Receiver Class III 2" # 13408
  • My contact at Curt Manufacturing confirmed, that the bolt holes on the Curt Trailer Hitch Receiver Class III - 2" # 13408, are spaced 4.35" on center from front to back. The forward most holes are spaced 39.937" apart on center, and the rear most holes are 39.437" apart on center.

  • Recommended Hitch Pin to Work with Curt Forged Ball Mount
  • We have hitch pins to work with the Curt Forged Ball Mount, part # C45456, however it does include one. I recommend the Curt Pin and Clip, part # C21510, for a standard pin, or even better, part # RH5-XL for a locking pin. If you also need a compatible hitch ball use part # 63840.

  • Ball Mount Recommendation for a 2014 Ford F250 with 2-1/2 inch Hitch
  • Originally, because the radius at the inside corners of the Ford OEM hitches were more rounded than usual, getting aftermarket hitch accessories that would fit was a problem. Ballmounts could be altered to fit by sanding off the powder coat at the corners. In the meanwhile, Reese has altered the design of the ball mount slightly by rounding the shank edges so that it will be compatible with the Ford OEM 2-1/2 inch receivers. I have confirmed this with Reese. The # RP45322 ballmount...

  • What Size Hitch Pin Fits Pro Series Cargo Carrier for 2 Inch Hitch
  • For a traditional pin and clip, I would recommend Curt's hitch pin and clip # C21510. This hitch pin and clip is designed to work with Class III, Class IV, and Class V trailer hitches. If you are looking for a locking hitch pin, I recommend this stainless steel lock # 40107. This locking hitch pin is designed to fit Class III and Class IV hitches.

  • Can Flash Ball Mount be Used for Trailer With GVWR of 15,000 lbs?
  • The Flash Ball Mount # DTBM5400 you purchased does have a tongue weight capacity of 2,000 lbs but its towing capacity is actually 14,000 lbs. The GVWR of your trailer is 15,000 lbs, which is the max capacity it can handle so with 10,000 lbs of tractor and gear, the weight of the trailer is going to determine if the Flash and its 14,000 lb capacity can accommodate your needs. If the trailer and gear is at or close to 14,000 lbs I recommend going with a higher capacity ball mount. In regards...

  • Extra-Long 2-1/2-Inch Ball Mount Rated for at Least 15,000-lbs
  • We offer both fixed and adjustable ball mounts that will fit a 2-1/2-inch hitch like the one on your 2016 Ford F-350 Super Duty and you can see them all on the linked page. We do offer an extra-long fixed ball mount rated for 16K, part # BWBMHD30214, that has either a rise or drop of 6-inches. This ball mount uses a 5/8-inch hitch pin or lock such as # C21510 or # RH5-XL, and it takes a hitch ball with a 1-1/4-inch shank diameter such as # C40030.

  • Hitch Pin with Hole in the End for the Clip for a 2015 Ford F-250 with 2-1/2 Inch Trailer Hitch
  • Curt hitch pins # C21500 and # C21510 have holes in them for the clip. Or you might like MaxxTow pin # MT70053 better. It has a handle that makes handling the pin easier and it has a hole for the clip. The useable length is 3-5/8 inches so it is going to clear a 2-1/2 inch hitch better than the other 2 options above.

  • Options for Securing Au-Tomotive Gold Honda Trailer Hitch Cover AUT-HON-C In Hitch Opening
  • The Au-Tomotive Gold Honda Trailer Hitch Cover # AUT-HON-C does not include a pin-and-clip nor a gasket for installation. A pin-and-clip kit # C21510 is available, as is a locking anti-rattle kit # 63232 which will both prevent theft and eliminate any potential for rattle in the hitch opening. This hitch cover will easily fit in your 2-inch hitch.

  • How to Prepare a 2" Trailer Hitch Receiver for Winter Weather
  • In order to prevent rust from accumulating inside the trailer hitch receiver while not in use I recommend using a hitch cover like the Tow Ready Black Plastic Hitch Cover for 2" Trailer Hitches part # TR1202 to cover the receiver tube opening and a standard hitch pin like the Curt Pin and Clip part # C21510 to cover the hitch pin hole.

  • Pin and Clip and Locking Hitch Pin Recommendation for US Air Force Trailer Hitch Cover # AUT-AIRW-C
  • The US Air Force Trailer Hitch Cover # AUT-AIRW-C that you referenced does not come with a hitch pin. For a standard hitch pin you would want the part # C21510. For a locking hitch pin you would want the part # 5201.

  • 18 Inch Hitch Extender that Fits 2 Inch Trailer Hitch
  • The # D30 you referenced is for hitch fabrication and it sounds like you simply need a hitch extender. There is an 18 inch extension, the Curt Extender for 2" Receivers -18" Long # C45796 which you can use with a bike rack. The only thing to note is that the use of any extender will reduce the overall capacity of the hitch by 50 percent and that includes the tongue weight capacity. This is important because the tongue weight capacity of your hitch is the max weight your bike racks...

  • Can Chains be Connected to Curt Hitch Extender
  • There is not a place for safety chains to connect to the 18" Curt Extender for 2" Receivers # C45796 so you would need to get new safety chains as well; I have added a link to our selection of safety chains for you to check out such as the 60" # C19749. Keep in mind you will need Pin and Clip # C21510 in order to attach the extender to your current hitch, and that an extender is going to reduce the capacity of your current trailer hitch by 50 percent.

  • Recommended Pin And Clip To Replace Lost Pin On Curt Folding Cargo Carrier For 2 Inch Receivers
  • It sounds like the pin that allows the cargo carrier to be tilted up or down is what you are missing. I have attached a photo of the pin on a cargo carrier. If that is the pin and clip that is missing I recommend using part # C21510 as a replacement. This pin is designed for 2 inch and 2-1/2 inch trailer hitches and my contact at Curt said the pin would work well for you.
