Simple straight forward installation! Exactly what I wanted.

2007 Chevrolet Silverado 1500

This is my first hitch. I decided to go this route after finding out the dealership wanted over 1500 to install rails hitch and plug.
Install was not too aweful bad I did the install in about 4 hours of everything. I took my time so nothing would be screwed up. The install videos where awesome and very discriptive.


you guys are great to work with will be buying all my products through you!

2004 Dodge Ram Pickup

Great ,fast service.

2002 Dodge Ram Pickup

For as expected, 10'is a bit long for a short bed truck, just had to coil up the extra and the it up under the bed. Works well though and installation was easy, no cutting wires!


Products arrived in Alaska within a couple of days of making the order online. Easy to find the product needed on the website. Great installation instructions, both video and written. Perfect fit with no fuss.


Installation was a breeze, works perfectly.


Still working good after a year... Wiring was easy to install..


Fits great ,works fine.

  • Will Curt 5th Wheel/Gooseneck Custom Wiring Harness Fit a 2004 Dodge Ram 1500
    Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole Connector - 10' Long Item # C56001 is designed to fit if your 2004 Dodge Ram 1500 came with a factory installed 7-Way trailer connector. It plugs in line with the factory connectors and provides a second 7-Way connector you can mount in the truck bed (or anywhere that it will reach). If your truck did not come with a factory installed 7-Way let me know what it does have and I can make some recommendations to add a 5th wheel/gooseneck...

  • Troubleshooting Short to Battery Message with Prodigy P3 Controller When it Rains
    Water is seeping into the new 7-way most likely and is causing a short between the 12 volt output circuit and the brake output circuit. The water is somehow getting introduced into the round connector behind the 7-way. It could also be at the 7-way at the rear of the vehicle too. I'd recommend taking the connector apart to allow it to dry and then using dielectric grease like part # 11755 which will prevent the water from getting back in.

  • Is 7 Foot Long 5th Wheel Trailer Wiring Harness Long Enough for an 8 Foot Truck Bed
    The 7 foot long Curt fifth wheel wiring harness your purhcased, part # C56071, should fit just fine in your truck even with the 8 foot bed. However, you probably will only be able to reach the rear part of the bed behind the wheel wells. There is the 10 foot version, part # C56001, which will likely increase your options as to where in the bed you can install it due to the added length.

  • Will Curt Fifth Wheel/Gooseneck Hitch 7-Way Fit a 2000 Dodge Ram 3500
    For your 2000 Dodge Ram 3500 the Curt Fifth Wheel Gooseneck wiring kit part # C56001 has been confirmed as a fit to allow you to install a second 7-way up in the bed of your truck for easy connection to a gooseneck or fifth wheel trailer. For just a replacement 7-way you would need the part # PK11893.

  • Will Pro Series 5th Wheel Trailer Hitch and Universal Install Kit Fit a 1998 Dodge Ram Long Bed
    Yes, the Pro Series 5th wheel trailer hitch with universal installation kit, # PS30128, will fit your 1998 Dodge Ram long bed. I have included a link to the instructions for the universal kit and a video showing an example installation on a similar truck you can use as a guide, though the installation will not be exactly the same. I also recommend adding an in-bed 7-Way trailer connector, # C56001, to make hooking up easier. I have linked a video and the instructions for the wiring as well.

  • Recommended Truck Bed Wiring for a 1997 Dodge Ram
    With your 1997 Dodge Ram already having a factory towing package, I suggest going with the Curt # C56001. This will T off directly from the ports in the back of your current wiring and is a plug an play option.

  • Industry Standard Rails for a 5th Wheel Hitch in a 1999 Dodge Ram Pickup
    I have a solution for you, it sounds like you have the 5th wheel hitch and the actual rails the hitch attaches too but are needing the custom mounting hardware for your 1999 Dodge Ram Pickup. You are going to better off getting a new set of mounting hardware and rails because the mounting hardware needs to match your truck and the rails. For a set of Industry Standard Rails we have the B&W Universal Base Rails and Installation Kit for 5th Wheel Trailer Hitches # BWRVR3200. This will provide...

    The Curt 30K Gooseneck Hitch with Installation Kit # C640-635 is a complete goose neck hitch system that includes the frame brackets, hitch head and 2-5/16-inch hitch ball. It is a confirmed fit on your 1996 Ram. For a wiring harness you can use # C56001.

  • Will Curt C61509-52 Overbed, Folding Ball Gooseneck Hitch Fit a 1996 Dodge Ram 2500
    According to Curt, the installation rails included with the # C61509-52 Gooseneck Hitch will fit 1500, 2500 and 3500 series models of the 1996 Dodge Ram truck, unless it's a cab/chassis truck instead of a pickup. If you'd like to install a 7-way trailer connector in the truck bed, you could do so using part # C56001.

  • Recommended Install Kit for Valley 5th Wheel Hitch on 1998 Dodge Ram 2500
    Although Valley is not around any longer, we used to carry their products so I can say with confidence that their fifth wheel hitches were compatible with industry standard bed rails constructed by Reese, Curt Husky and others. Reese offers a Universal fifth wheel hitch install kit, part # RP30035 that uses industry standard fifth wheel bed rails that would be compatible with your Valley sliding hitch. This is a similar kit to the Curt # C16200. Since your truck bed is 8 feet long, you...

  • Recommended Fifth Wheel Install Bracket/Rail Kit for 1997 Dodge Ram 3500 Dually
    Actually, B & W Hitch offer a reasonably priced 5th wheel bracket/rail kit that works with industry standard rail compatible hitches like your Husky. I'd recommend the # BWRVR3200 install kit. The bed rails are compatible with hitches from Reese, Draw-Tite, Husky, Curt , B & W, Demco and Valley among others. If you don't already have a 7-way trailer connector in the truck bed, you can install one using part # C56001

  • 5th Wheel Installation Kit for 1998 Dodge Ram Pickup
    We do have 5th wheel hitch installation kits that include the frame brackets, hardware and hitch base rails. These are industry-standard rails that work with all brands of standard 5th wheel hitch. I recommend the Husky custom install kit # HT31404-686. This kit fits both 6-foot and 8-foot bed models. Drilling is required. There is not a no-drill kit for your truck. For an in-bed wiring harness you can use part # C56001.

  • 5th Wheel Sliding Hitch Compatibility With Gooseneck Underbed Hitch
    With your current gooseneck hitch, you can use the Hi-Rise Gooseneck-to-5th-Wheel Trailer Hitch Adapter by Bulldog, Draw-Tite and Reese # 9480. The issue is that you don't have a sliding option with that hitch so it would give you very limited turning. An option is to use the Curt X5 5th Wheel Base Rails Adapter for Curt Double Lock Gooseneck Trailer Hitches - 20,000 lbs # C16210 that SHOULD be compatible with your gooseneck hitch. Based on all I can research it looks like it will fit,...

  • Does OEM 5th Wheel Hitch for Ram Fit 2006 Dodge Ram 3500 Short Bed
    There are 5th wheel hitches available for your truck, but the OEM trailer hitches for are designed to fit the factory puck system of the newer Ram trucks, so they won't work in a 2006 Dodge Ram 3500 short bed. The Ram OEM 5th wheel hitches are made by Curt, so if you like them you can add the same type of brand/model, but will need to add base rails to your truck. What you can use is the following: - Curt Q20 5th Wheel Trailer Hitch with R20 Slider # C16536 - Curt Semi-Custom Fifth Wheel...

  • Recommended 5th Wheel Hitch and Installation Kit for 2006 Dodge Ram 2500 Mega Cab Pickup
    The main benefit of a 5th wheel hitch that has a 4-way pivoting head is easier hitching and un-hitching. The ability to pivot in all directions means the head will be better able to shift as required to accept the king pin, and of course to release it too. Ride quality is not so much a benefit of this feature. Since your trailer has a Lippert Turning Point pivoting pin box for improved turning clearance you can use a fixed (non-sliding and non-cushioned) type 5th wheel hitch. For an above-bed...

  • 5th Wheel Base Rails for a 2008 Dodge Ram 1500 Quad Cab w/ 6.5' Bed
    For your 2008 Dodge Ram 1500 Quad Cab with 6'6" bed you can use the Curt Custom Fifth Wheel Installation Kit # C16419-204. This will provide you with a set of Industry Standard Rails (ISR) to use a 5th wheel hitch like the Curt A20 5th Wheel Trailer Hitch w/ R20 Slider # C16541 or any other 5th wheel hitch that attaches to Industry Standard Rails.

This will work for your truck, and you only need to add base rails if you don't have them, the Curt Universal Fifth Wheel Base Rails - Gloss Black Finish # C16104 or Carbide Black Finish # C16204.

  • Installation Brackets for 5th Wheel Hitch to Be Installed in 2007 Dodge Ram 1500
    Any brand of industry-standard 5th wheel hitch will fit into any brand of industry-standard base rails, but the frame brackets that secure the rails to the truck frame should not be mixed with base rails from another maker since there can be compatibility issues. So in other words, you will want to use brackets from the same maker as your base rails (again, the hitch brand does not matter here).

  • Which 5th Wheel Base Rails Are Correct For 2000 Dodge Dakota?
    For your 2000 Dodge Dakota you will want to install B&W Universal Base Rails # BWRVR3200. This fits your vehicle and offers compatibility with any standard 5th wheel hitch such as B&W Patriot, Curt, Draw-Tite, Hidden Hitch, Husky, and Reese. If you don't already own a compatible 5th wheel hitch then I would go with a sliding hitch so that you have more turning clearance. The B&W Patriot 5th Wheel Trailer Hitch w/ Slider - Dual Jaw - 18,000 lbs # BWRVK3270 would be a great option to fit...

  • Recommended 5th-Wheel Hitch for 2005 and 2006 Dodge Ram 3500 w/ 6 Foot Bed
    The Curt Q25 5th Wheel Trailer Hitch # C16265 referenced in your question is compatible with standard, above-bed base rails. If there are standard, above-bed base rails installed on both the 2005 and 2006 Dodge Ram 3500, then this hitch will technically fit either truck. However, since you mentioned that your truck has a shorter, 6 foot bed, it is instead recommended to use a sliding 5th-wheel hitch in order to provide proper clearance when making turns.

    The Curt E16 5th Wheel Trailer Hitch - Slide Bar Jaw - 16,000 lbs # C16115 is large enough to tow a 11,200 lbs trailer regardless of the length. For your 2005 Dodge Ram 2500 long bed I recommend the Curt Custom Fifth Wheel Installation Kit for Dodge Ram - Carbide Finish # C16420-204 which will fit your truck frame without any drilling.

  • Where Should King Pin Sit in the Bed of a 1997 Dodge Ram 2500 for 5th Wheel Towing
    Typically the king pin will be located directly above, or slightly forward of the rear axle on any given pickup. If you were to install a universal base rail kit like the Reese # RP30035 on your 1997 Dodge Ram 2500 the (linked) instructions state that the king pin will be about 2" forward of the axle center. I have attached a picture of the instructions that show where you would install the base rails in relation to your truck bed. I recommend going with the Reese single-jaw 5th wheel...
