  • Hitch Extender for 10,000 lb Travel Trailer Compatibility
    I wish you would have asked this question prior to your purchase of the Curt Extender # C45791, because this extender will not work for your application. It is rated for the 3,500 lb total trailer weight towing capacity and because it is an adapter will also decrease your tongue weight rating of your trailer hitch by 50%. Instead, you may want to consider the Brophy Ball Mount for 2" Hitch # BH20. This ball mount is capable of towing 10,000 lbs and has a measurement of 13-1/4 inches...

  • Bolt-On Trailer Mounted Leg Replacement Rated For 5,000lbs
    I believe you're referring to is the Pro Series Round, Pipe-Mount Swivel Jack # PS1401440303, and the pipe this mounts too cannot be bolted on, it must be welded on. For this reason I recommend the Fulton Marine Jack - Square Tube, Fixed Mount # HD50000101. This jack has a capacity of 5,000lbs and has a total lift of 28"; this jack is used on trailer frames up to 3" wide and 5" tall.

  • Recommended Bike Rack And Shank For Clearance on 2014 Honda Odyssey
    The Receiver Mount for Advantage SportsRack V-Rack 2 Bike Carrier - 2" Hitches # HE6007 has a measurement of 6-1/4 inches from hitch pin hole to tube end. This will not be long enough to even clear your bumper with some of the hitches available for your 2014 Honda Odyssey as you can see in the attached video. The Curt Clamp-On 3 Bike Rack for 2" Ball Mounts - Towing # C18013 can be used with Ball Mount 3/4" Rise or 2" Drop, Extra Long # D-26 or the Curt Hitch Extender for 2" Trailer...

  • Can I Use My 2 Aventon Adventure Lectric Step-Thru E-Bikes With the Sport Rider SE # HLY84FR?
    From the sounds of your question, I assume you are talking about the Hollywood Racks Sport Rider SE # HLY84FR. If this is the rack you are referring to, yes! It works with 20" diameter tires as long as you have the adapter # HLY24FR for each bike. This adapter does not come with the rack itself. This rack is a great choice because it has a super high 80 pound per bike weight capacity. It also accommodates fat bike tires up to 5 inches wide (if you have them). As far as your step-thru...

  • Recommended Aluminum Folding Hitch Cargo Carrier for Corrosion Resistance
    We have one aluminum folding option for you and it is the 19x60 Curt Cargo Carrier for 2" Hitches - 500 lbs # C18100. This carrier is well made and will store close to your vehicle when not in use. We have another aluminum option also rated for 500 lbs capacity but it doesn't have the folding option. It's the Flint Hill Goods 29" x 49" Carrier w/ 60" Ramp - 2" Hitch - 500 lbs # FHG69ZR.

  • Can the Blue Ox Hitch Extender Be Used for Towing a Trailer
    I do have a hitch extender for you that can be used for towing a trailer but the Blue Ox Hitch Extender for Tow Bars part # BX88265 that you referenced is intended for flat-towing only as with most of Blue Ox products for that matter. The 10,000 lb maximum towing capacity that this extender has is in regards to the weight of the towed vehicle in a flat-tow setup, not the weight of a trailer in a bumper pull setup. I do however understand how that can be confusing. If you need to use a...

  • How Long are the Curt Hitch Extenders C45791 C76DR?
    Hey Kenyon. Both the Curt Hitch Extender for 2" Hitch Receivers item # C45791 and item # C76DR are 8" long hitch extenders. I have attached a couple of diagrams below. Both have a 3,500 lbs towing capacity and a 350 lbs maximum tongue weight. Please note that using any hitch extender will reduce your hitch's capacities by 50%. What are you needing a hitch extender for?

  • Height of Vertical Square Tube on RockyMounts BackStage 2 Bike Rack # RKY10002
    From the center of the hitch pin hole to the top of that small vertical post at the end of the shank on the RockyMounts BackStage # RKY10002 there is a distance of 4-3/8 inches. I have attached an image to assist. You can use this measurement to ensure the tailgate on your Tacoma will drop all the way down with the rack attached and the platform swung away to the side. I have included a short video demonstration on this carrier that you can check out as well.

  • Recommended Anti-Rattle Hitch Pin for 2" Hitch Extender on 2017 Nissan Murano
    The Curt Hitch Extender # C45791 will give you an additional 8" of room (measured from hitch pin hole to hitch pin hole) though please keep in mind that an extender is going to reduce the capacity of your current hitch by 50 percent. So if you had Curt hitch # C13205, for example, on your 2017 Nissan Murano, its towing capacity would go from 3,500 lbs to 1,750 lbs and its tongue weight capacity would be reduced from 350 lbs to 175 lbs. If you do have enough capacity even with the reduction,...

  • What Hitch Bike Rack Do You Recommend for a 2021 Mercedes GLC?
    For a bike rack that fits your 2-inch trailer hitch on your 2021 Mercedes-Benz GLC, it really depends on if you have heavier bikes, bikes with fenders, and the number of bikes that you wish to transport. If you have heavier bikes or bikes with fenders, I recommend the Hollywood Racks Sport Rider SE # HR200Z (2-bike version) and the # HR1400Z (4-bike version). the Sport Rider SE has a maximum per-bike weight capacity of 80 pounds, and the frame attachment style of the rack will allow you...

  • Hitch Extension Compatibility With Front Hitch on 2013 Ford F150 for Winch Mount Fit
    For your Warn Zeon 10 Winch on your 2013 Ford F-150, the Curt front mounted receiver # C31068 has a vertical load of 500 lbs and a line pull ratting of 9,000 lbs. Because of the recessed receiver, I recommend the Curt Hitch Extender for 2" Hitch Receivers - 8" Long # C45791 which reduces that vertical load limit by 50% and brings it to 250 lbs. I recommend using hitch lock # e98880 and getting the pins keyed alike by selecting that from the box on the product page.

  • Will the RockyMounts Westslope 3 Bike Rack Fold Up on a 2011 Rav4 with a Spare Tire?
    I have a solution for you. If you have a compatible 2-inch hitch like the etrailer Trailer Hitch Receiver - Custom Fit - Matte Black Finish - Class III - 2" # e98864, the distance between the center of the hitch pin hole to the end of the spare tire on your 2011 Toyota RAV 4 is about 8 inches. With that distance, the RockyMounts WestSlope 3 # RKY10223 will interfere with the spare tire because there is only 5 inches from the center of the hitch pinhole to the rack when it is folded up....

  • Hitch Extender Recommendation for Towing Trailer with Truck Camper
    Instead of using a tongue extender for your trailer you could use a hitch extender like the part # C45791 to basically get the same effect. This is an 8 inch extender that would work well for you. You should note that using an adapter like this will cut the capacity of the hitch on your truck in half.

  • Can Hitch Extender Be Used with Small Trailer Towing Lawn Equipment
    The deal with hitch extenders is that they cut the capacity of the hitch they are installed in by 50 percent due to the added length and leverage. If your tow vehicle has twice the towing capacity as what your trailer will weigh this adapter part # C45791 would work well. This adapter by itself has a capacity of 3,500 lbs so the adapter would easily work on a 2,500-3,000 lb trailer.

  • Recommended Hitch Extender for a 2015 Jeep Wrangler Rubicon Carrying Kuat NV 2.0 Bike Rack
    I can tell you have been doing some research and know what you are looking for. Just as a blanket statement, any hitch extender will reduce the tongue weight of your trailer hitch receiver even if it has a higher weight capacity, like the Roadmaster Anti-Rattle Hitch Extender # RM-071-1075 that you referenced. Both the Curt # C45791 and the Brophy # HE06 options will still cause some play by themselves because of the weight sitting further out from your trailer hitch pin hole. What I...

  • Measurement From Center Pin Hole to Shank of the Curt Hitch Extender C45791

  • How Can Longer Ball Mount Not Reduce Hitch Weight Capacity
    Technically any additional length is going to increase leverage on the trailer hitch. But there isn't an exact standard length ball mount so going super technical on how much the force multiplied when the ball mount is beyond a certain length is just not something our manufacturers do. So when you combine that with fact that most ball mounts are not that much longer than others the tongue weight capacity of a vehicle is not reduced when using a longer ball mount like the part # 80232....

  • What is the Max Tongue Weight of the Yakima StraightShot Y69VR?
    I spoke to Yakima about the StraightShot # Y69VR extender, but they have only tested this with Yakima accessories. Due to this, it doesn't have a listed tongue weight. With that being said, the Yakima bike racks and other accessories are going to weigh quite a bit less than 320 pounds and I do not recommend going this route. Though all extenders like this will cut the tongue weight of your hitch in half, I do suggest going with the Curt # C45791. This has been tested with many different...

  • Effect of Using Extra-Long Ball Mount for Towing
    Use of an extra-long ball mount like # 80232 will not reduce a hitch's towing weight capacity the way that use of a separate extender/adapter will. Extenders like # C45791 and # D-192 actually do reduce the hitch towing capacity by 50-percent. Weight distribution hitch systems such as # C17501 should not be used with any type of hitch extender or adapter. A friction sway control unit like # 83660 can be used with an extra-long ball mount like # 80232 by adding a sway control bracket like...

  • Why Does Use of Hitch Adapter/Extender Reduce Hitch Tongue Weight and Trailer Weight Ratings
    Any type of hitch adapter or extender will have the unavoidable side-effect of causing a loss of about half of your hitch's rated capacity, both its tongue weight (TW) and it's gross towing weight (GTW). Hidden Hitch extender # HE18 and Curt Hitch Extender # C45791 both cause a loss of capacity because they change the geometry of the hitch set-up. The added length of the adapter will allow greater leverage to be applied to the hitch tube by the attached trailer or accessory; this is what...

  • Can I Add A Hitch Extender To My GearSpace 34 Cargo Carrier On A 2020 Mercedes-Benz Sprinter 2500
    I did some online research and I think I have a solution. You can add a hitch extender. Your 2020 Mercedes-Benz Sprinter 2500 has a maximum gross trailer weight of 5,000 lbs. This will make your vehicle's maximum tongue weight 500 lbs. The GearSpace 34 Enclosed Cargo Carrier for 2" Hitch - Slide Out - 34 cu ft - 300 lbs - Light Gray, part # HGK826, weighs 160 lbs and it has a maximum weight capacity of 300 lbs. If you use a hitch adapter to gain more space, you will reduce the maximum tongue...

  • Can a Dual Hitch Adapter and Hitch Extender Be Used Together For Towing with a Bike Rack
    I do have an option for you but you cannot use multiple hitch adapters together like the dual hitch adapter part # D-192 and the hitch extender part # C45791 for example. This would create too weak of a connection point and would limit your towing capacity to almost nothing. If you need to tow a trailer and haul a bike rack at the same time a much better option for you would be with the Curt Multipurpose Ball Mount part # D210 or the Jack-It 2 Bike Rack part # LC429756. If you have a bumper...

  • Will the GearSpace 34 Clear the Rear Doors on a 2017 Pleasure Way Motorhome
    It sounds like you are trying to determine whether or not the GearSpace 34 Enclosed Cargo Carrier part # HGK819 will slide out and allow for the rear doors to open on your 2017 Pleasure Way Motorhome. If that is the case then what you will need to do is open the rear doors on your motorhome and then measure from the furthest point out back to the center of hitch pin hole on your trailer hitch. As long as this distance does not exceed 32" then the GearSpace 34 will clear the rear doors....

    The Thule T2 Pro XTR 2 Bike Platform Rack # TH83JV requires a minimum of 1-1/2 inches from the center of the hitch pin hole to the end of the receiver opening of your hitch according the manufacturer, but we have customers that have confirmed it will work without it. If you want an adapter to follow the manufacturer's recommendation, I have a work around option for you.
