The trailer hitch is a super heavy duty trailer hitch. The only problem with the trailer hitches is very heavy to install underneath of the truck. I have a truck with a 10 inch drop bumper they was after market and they research the trailer hitch and said it would fit and it fits great love the trailer hitch installation had all the right Hardware all grade 8 bolts nothing cheap about it love it 705410

Great hitch and perfect fit for my truck. Was really a 2 man job but got it done by myself. The factory hitch is kind of a pain to get off on the 2008 HD as there are bolts up right at the bumper line. The new one fit like a glove i did add to shackles to allow my safety chains to attach a little easier. Great product great customer service. etrailer is the best i love these guys have bought lots of stuff from them and will definitely continue to buy more. Thanks 469399

Everything seems fine and it looks great. I tow a 12k lb trailer a few times a year with no issues. I took off my super truss double 2in because I needed the 2.5in opening. The super truss used 10 bolts to attach with some bolts going all the way up to the top of the frame. The Curt only has 6 bolts going to the bottom of the frame. 716546

When I discovered that my factory installed hitch was only rated for 7500lbs I knew I needed something different. Etrailer came through again. This hitch is exactly what i needed. My camper has a GVW of 12K and i have the weight distribution hitch. Easy to install and the 4" drop just what i needed to lower my bumper also. 595135

  • Recommended 2-1/2 Inch Trailer Hitch for 2008 Chevy Silverado 2500 with Best Ground Clearance
    We haven't had the chance to install the Curt Class V Trailer Hitch Receiver # C15703 on the 2008 Chevy Silverado 2500 so I don't have exactly how far beneath the bumper the receiver will sit, however I did go out to our warehouse to take a measurement that will help you determine this. From the front bracket where the hitch will attach to the frame rails of your Silverado to the bottom of the receiver there is a distance of 9-3/4 inches. You can take this measurement down from the...

  • Will Installing Curt # C15703 on 2006 Silverado 2500HD Interfere with Larger than Stock Spare Tire
    Curt does not have that measurement available, but you can determine this for yourself by taking some measurements from the underside of your truck. Using the diagram I edited for you, locate the weldnut that would serve as the rear-most attachment point for the hitch. From the center of this bolt hole, measure rearward toward the bumper six inches. From that point, measure forward to the closest point of the differential. If this distance is greater than the diameter of your spare tire,...

  • Distance from Bumper to Top of Curt Trailer Hitch C15703 on a 2005 Chevy Silverado 2500
    Curt Trailer Hitch Receiver # C15703 hangs pretty low on a 2005 Chevy Silverado 2500. From the bottom of the bumper to the top of the hitch receiver it is approximately 4 inches. I have included a picture showing the gap. A similar hitch, # C15302, which also fits your truck is much tighter to the bumper with only a fraction of an inch of space between the bumper and receiver.

  • Class V Trailer Hitch with No Drilling for a 2003 Chevy Silverado 3500

  • Best Trailer Hitch for a 2008 GMC Sierra 2500
    The best trailer hitch for your 2008 GMC Sierra 2500 will vary depending on what you're going to use it for and possibly whether you have an 8 ft. or 6-1/2 ft. bed. If you need to haul a lot of weight I would suggest the Curt Class V CD 2-1/2" # C15703. This will get the most out of your truck for your dollar and will work with either length of truck beds. The Curt Class III # 13208 will also work with both bed lengths and would be more appropriate if you're not hauling as much weight. I...

  • Drop of Curt Class V Trailer Hitch # C15703 for 2007 Chevy Silverado Classic 3500
    From the underside of the frame to the top of the crossbar tube would be 5.13 inches, and from the underside of the truck frame to the lowest point on the hitch, which is the bottom of the side plates, is 9.83 inches. You can see these dimensions on the photo I've edited for you. I've also linked to an install video for you.

  • Trailer Hitch for a 2006 Chevy Silverado 2500HD with Reading Utility Body
    Since you have that utility body the custom fit hitches for the 2006 Chevy Silverado 2500HD will not work. What you will need is a weld-on hitch. I have included a link to the options for you. A hitch like # 15902 creates a drop of 10.865 inches from the truck frame. Installation should be performed by a qualified professional welder.

  • Exact Measurement of Receiver of Curt Trailer Hitch 15703
    I went out to the warehouse with digital calipers to get the exact measurement of the receiver of the Curt Trailer Hitch # C15703 and found it to be 2.55" though it is possible for the hitch that is shipped to you to have slightly (and by slightly I mean a couple hundredths or thousandths of an inch) more or less room in the receiver. There is always going to be some slight play but you can reduce this with the use of the Blue Ox Hitch Receiver Immobilizer II # BX88225 which is designed...

    There are TorkLift Camper Tie-Downs that will work with the Curt Trailer Hitch # C15703 for your 2006 Chevy Silverado 2500HD but it is different than the one you referenced. The tie-downs that fit an '06 Silverado 2500HD with a 6-1/2 foot bed and aftermarket hitch do require the hitch to have a side plate with a 4" x 4" footprint, and as you can see by the accompanying photo of the measurements of Curt Hitch # C15703, it does meet those requirements.

    Good news, I was able to go out to our warehouse and measure the Curt Class V Hitch # C15703. This Class V Trailer Hitch has a dimension of almost 5 inches from the top of the bolt holes to the top opening of the receiver hitch opening. This should accommodate the space you require for your after market bumper. This Curt trailer hitch will fit both the 6-1/2 and 8 foot bed sizes of the 2002 GMC Sierra 2500HD. I have linked an install video of the Curt hitch for your convenience.

    The Curt Trailer Hitch Receiver - Custom Fit - Class V CD - 2-1/2" # C15703 for your 2004 Chevy Silverado 2500 HD does not come with any adapters. It sounds like you are interested in a reducer like the Curt Hitch Receiver Reducer Sleeve - 2-1/2" to 2" # C45405. This will allow you to use 2 inch accessories with your 2-1/2 inch receiver.

  • Hitch Extension Recommendation for a 2004 GMC Sierra for Towing 5,500 lb Boat Trailer
    First thing you will need to do is install a hitch with a 2-1/2 inch opening like the Curt Hitch part # C15703 so that you can use a longer hitch extension that is going to have a decent amount of capacity. Then for a hitch extender the part # C45048 would be a great option as it has enough capacity and can be used to give 24 or 34 inches of extension.

  • Heavy Duty Hitch for my 2003 Chevrolet 2500 HD
    After checking some information it appears that the maximum towing capacity of the 2003 Chevrolet 2500 HD is 12,000 lbs. This would be the max and depending on options it may be lower than that. I recommend using the owner's manual to determine exactly what the towing capacity of your exact configuration is. With that said the Curt Trailer Hitch Receiver part # C15703 is a very heavy duty hitch which will exceed your vehicle's capacity. The BulletProof Hitches Adjustable 2-Ball Mount...

  • Can Longer Hitch Extender be Used on a 2006 Chevy Silverado 2500HD
    If you have a 2-1/2 inch hitch on your 2006 Chevy Silverado 2500HD like the Curt hitch part # C15703 then you could use a Titan hitch extender like the part # RP45292 if you used it in the 24 inch length and used a weight distribution system since a WD system gives the extender a higher towing capacity of 8,000 lbs instead of 6,000 lbs. For a weight distribution system the part # RP66084 would be a great option. It has a tongue weight range of 600-1,200 lbs and features only sway control...

These tie-downs are specific to a number of variables which you left out but assuming your '06 Silverado 2500 has an 8 foot bed and does not have any running boards you will need TorkLift Custom Frame-Mounted Camper Tie-Downs - Front # TLC2204 and the TorkLift Custom Frame-Mounted Camper Tie-Downs - Rear # TLR3501.

  • 2-1/2 Inch Class V Trailer Hitch for a 2000 Chevy Silverado 2500HD 6.0, 5-Speed, 14 Bolt Rear End
    The 2000 model year was a split model year for GM trucks (actually it started for the 1999 model year but continued until about 2002). This is when they went from being C or K series to being badged as Silverados/Sierras. So the issue with filters and whatnot may have stemmed from that. So for a 2000 there were both C/K series and Silverados. To make things more confusing Silverado was a trim on the C/K series trucks. So it is possible you have a 2000 C or K series 2500HD with the Silverado...

    The frames of the 2004 Chevy Silverado 2500 HD with short beds aren't going to be any different than standard beds or those trucks with hitches already installed, you just would not be able to install this hitch receiver as part of a dual hitch setup. The Curt # C15703 does not allow for that setup and can only be used as a single installed hitch, but all you would need to do is remove your factory 2" receiver and install this one and it will work just fine.

This hitch will allow you to use the Titan Hitch Box Extension for 2-1/2" Trailer Hitches, 41" - 48" Long # RP45018. This will give you a towing ability of 4,000 lbs at full length so your aluminum 19 foot fishing boat, motor, and trailer should be well under the rated capacity.

    Going to an 18,000 pound rated trailer hitch on your 2006 Chevy Silverado 3500 will indeed require you to switch to a 2-1/2 inch receiver. This is not a problem though because as you mentioned we have various adapters available such as the Curt # C45405 that will reduce this opening to 2 inches so you can continue to use your existing accessories. Because the sleeve slides into the hitch receiver it won't restrict the use of your accessories at all in terms of capacity or function and it...

  • Fit of Class V Trailer Hitch for 2002 GMC Sierra 2500 HD
    For a 2002 GMC Sierra 2500 HD, you'd want to use the Curt Class V hitch, part # C15703. I checked with Curt, and found that the drop of this hitch (measurement from the mounting flange to the top of the crossbar) is 5.13 inches, as shown in the photo I've provided. The # C15703 has a 2-1/2 by 2-1/2 receiver opening. According to Curt, their # C15323 Class V hitch you had asked about isn't a fit for the 2002 Sierra 2500 HD model, it's only a fit for the 1500 and the 2500 LD model. If...
