  • Reese 5th Wheel Bracket Install Kit for 2016 Chevy Silverado 2500HD
  • We can help you with just the Reese frame brackets for 5th wheel base rail installation in your 2016 Chevy Silverado 2500HD with 6-1/2-foot bed and without the factory rail kit. For just the frame bracket and frame hardware kit you can use part # RP50066. For hardware to attach the rails to the brackets use # RP58504. The complete base rail, bracket and hardware kit is part # RP50066-58.

  • Will Universal Reese Fifth Wheel Kit Fit 2003 Chevy Silverado 2500HD
  • The brackets you send in a picture of looks to be a universal bracket kit that would fit both the trucks you mentioned. Based on the picture it actually looks like you have the Reese universal rail kit part # RP30035. I attached a picture that matches what you have in your picture. This would be a fit for your 2003 Chevy Silverado 2500. The hardware kit needs to be replaced since it's one time use. For that you would need part # RP58504.

  • Parts Needed to Use ISR Base Rails in a 2018 Ford F-150 with 6-1/2' Bed
  • The correct custom bracket set and hardware kit for your 2018 Ford F-150 will depend on if you have 43" long or 48" long base rails. If you have 43" long base rails these are what is referred to as inboard rails and you will need to use part # RP50087 for the brackets and part # RP58430 for the hardware. If you have 48" long base rails these are what is referred to as outboard rails and you will want to use part # RP56034 for the brackets and part # RP58504 for the hardware.

  • Curt E16 5th Wheel Trailer Hitch and Rails Only for a 2012 Chevy Silverado 1500 Short Bed
  • Generally speaking if you have a short bed truck, like your 2012 Chevy Silverado 1500 with 6-1/2 foot bed, then you would need to use a slider hitch and not a fixed hitch. That is unless the trailer is very narrow or it has a tapered front cap that was designed to be towed by a short bed truck. Otherwise the trailer could make contact with the truck cab when making tight turns. If you already have frame brackets that you want to use then you would need to get the hitch and rails separate...

  • Brackets Only for Reese 5th Wheel Installation Kit # RP50074-58
  • Yes, you can get the brackets and hardware from kit # RP50074-58 by themselves. Use part # RP50074. But you will also need hardware # RP58504 to attach the rails to the brackets. The hardware is meant for one-time use only so the old hardware, if you still have it, should not be reused. The PR50074 instructions also call for an 11th bolt which you can add using # HT32059.

  • Parts Needed To Use an Old 5th Wheel Hitch and Base Rails on a New 2018 Chevrolet Silverado 3500
  • The pre-drilled holes in the bed of your 2018 Chevrolet Silverado 3500 will not line up with the holes needed to reinstall your Reese base rails. Unfortunately, the aftermarket base rail installation kits have been carried over from previous year trucks and do not line up with the manufacturers new pre-drilled mounting holes. In order to install the Reese 20K 5th Wheel Trailer Hitch w/ Round Tube Slider part # RP30083 in your truck with your existing base rails, you will need new custom...

  • Fifth Wheel Frame Brackets for a 2007 Chevy Silverado 1500 New Body with 5-1/2 Foot Bed
  • Fifth wheel brackets # RP50081 are actually for certain Ford trucks and will not fit your 2007 Chevy Silverado 1500 with 5-1/2 foot bed. The comparable brackets that do fit your truck (new body style) are # RP50064. If you do not already have the rails then I recommend # RP50064-58 which is the complete kit. If you do already have some 10 bolt rails then you would also need bolt kit # RP58504 because the hardware is not meant to be reused. With the 5-1/2 foot bed you would either...

  • For your 2005 Ram 1500 SLT it sounds like you simply need the Reese Quick-Install Custom Bracket Kit for 5th Wheel Trailer Hitches # RP50040. This will work with your industry standard base rails and 5th wheel hitch and comes with the bracket mounting hardware. It sounds like you already have the rails like # RP58058 but you may need the hardware which is # RP58504.

  • Brackets and Hardware Only to Mount Reese 5th Wheel Rails in a 2015 Ford F-250 Short Bed
  • Fifth wheel brackets # RP56016 are specifically for the longer Reese rails, # RP30153, which are 48 inches long. If your rails are Reese and 48 inches long by 7-1/2 inches wide by 1-7/8 inches tall then # RP56016 is the correct bracket kit. If your rails are shorter than 48 inches then you will need bracket kit # RP50026 instead. Bracket kit # RP56016 comes with hardware to mount to the truck frame but not the hardware to attach the rails to the brackets. For that hardware you will need...

  • Installing Valley 7052 Hitch and Rails on 2015 Chevy Silverado 2500 HD
  • Valley has been out of business for a while now, but the hitch and the rails will still work just fine as long as they remain operating properly. The rails are industry standard 10 bolt rails so they will attach to your 2015 Silverado 2500 HD using bracket kit # RP50066 which comes with hardware and then 10 Bolt rail hardware kit # RP58504. This will give you all you need to install the rails to your truck without any frame drilling necessary. You may also want to consider wiring harness...

  • Recommended Reese 5th Wheel Brackets for 2016 Chevy Silverado 2500 6-1/2 Foot Bed
  • Since you already have the Rails, I recommend the Reese Quick-Install Custom Bracket Kit for 5th Wheel Trailer Hitches # RP50066 which require no drilling into your frame rails. The hardware for these brackets is included. For your rails, I recommend the Replacement Hardware Kit for Reese 5th Wheel Base Rails # RP58504 as the hardware is only recommended for one time use. Then for your hitch, I recommend the Reese 5th Wheel Trailer Hitch w/ Square Tube Slider # RP30051 to allow the...

  • Bracket Kit Recommendation to Install Reese 5th Wheel Rails in bed of 2004 Dodge Ram 3500
  • We have just what you are looking for to install your current Reese rails and fifth wheel hitch in your 2004 Dodge Ram 3500. What you need is the Reese bracket kit # RP50140 which comes with brackets that are custom fit for your 2004 Dodge Ram. You'll also need the hardware kit part # RP58504 which connects the rails to the brackets. You may have this already but these kits are considered one-time use so it's important you replace them as well.

  • Re-installing 5th Wheel Rails On New Spray In Bed Liner
  • Adding a spray in bed liner will give you a different thickness, but can also give you uneven thicknesses. The manufacturer will tell you to remove the bed liner where the rails fit to ensure your system will work properly if the spray in liner is too thick in that location. They will also tell you to use new hardware like the Replacement Hardware Kit for Reese 5th Wheel Base Rails - 10 Bolt # RP58504 because the hardware is only intended for one time use and since you've removed it you...

  • 5th Wheel Frame Brackets Only for a 2014 GMC Sierra 1500
  • You can get just brackets and hardware without the rails for your 2014 GMC Sierra 1500. But I strongly advise against mixing bracket and rail manufacturers because compatibility could be an issue and because the parts are not tested together. For custom brackets you could use # RP50064. You will need some additional hardware though, # RP58504, since the bracket kit does not come with the same hardware that is included with the full kit, # RP50064-58. I have linked a video showing an...

  • Will Reese 5th Wheel Install Kit Frame Brackets from 2015 Chevy Silverado 2500 Fit a 2016 Silverado
  • The 2015 Chevy Silverado and 2016 Chevy Silverado use the same frame brackets so you can use them on your new truck. But you are not supposed to reuse the hardware because it is meant to be torqued down once. When the hardware is torqued down the bolts stretch so they won't fit the same a second time. For the brackets the hardware is # RP56001F if you have install kit # RP56001-53. And for the rail hardware use # RP58504. I am having the rail hardware added to our site and it can take...

  • Recommended Custom Fit 5th Wheel Base Rail Kit for 2014 Toyota Tundra 5-1/2 Foot Bed
  • The Curt Custom Fifth Wheel Installation Kit # C16465-204 is not a fit for a 2014 Tundra 5.5 foot bed. Instead you will want the Reese Quick-Install Custom Installation Kit w/ Base Rails for 5th Wheel Trailer Hitches # RP50084-58 as Curt doesn't have a fit for the 5-1/2 foot bed. If you just want the brackets they are # RP50084 and come with the hardware for the brackets. Then if you have the rails you will simply need to add hardware kit # RP58504.

  • Compatibility of the Bed Rail Kits Between a 2010 Ram 2500 and a 2015 GMC Sierra 2500
  • This will depend on what type rail kit is on the 2010 Dodge 2500. If the kit is the Reese Universal Installation Kit , like # RP30035, then the brackets and rails will work on the 2015 GMC. You will need to use new mounting hardware # RP58504. If the Rail Kit is on of the custom-fit kits, then this will not work on your 2015 GMC Sierra 2500. For this application I recommend the Reese Quick-Install Custom Base Rails and Installation Kit, # RP50066-58. This kit uses custom-fit below the...

  • 5th Wheel Frame Brackets Only for a 2011 Ford F-150 with 5-1/2 Foot Bed
  • For your 2011 Ford F-150 with 5-1/2 foot bed you can use Reese brackets # RP50081 if you have Reese rails. You will also need hardware kit # RP58504 for 2 reasons. First, the brackets only don't come with all the necessary hardware. Second, the hardware is meant to be torqued down only once and should not be reused. For Demco rails you would need # DM8552004 which does come with the necessary hardware.

  • Recommended Frame Bracket Kit for Reese Rails and Sliding Hitch on 2004 Nissan Titan

This semi-custom kit includes all the needed mounting brackets to install your 10-bolt base rails. As you mentioned in your question, this kit includes 4 carriage bolts that will need to be pulled through the access holes in the truck's frame with the supplied pull wire.

If your rails do not look like the ones for RP30035 then I recommend replacing the whole kit, rails included, with custom install kit # RP50082-58.

  • Can 5th Wheel Install Brackets and Rails from a GMC Fit on a 2011 Ford F-150 with a 5-1/2 Foot Bed
  • First of all the rails will likely work for you. Although it could depend on if you need new brackets or not. We recommend combining rails and brackets from the same manufacturer so you'll want to use brackets that are the same brand as the rails. For example, if he has Reese rails, part # RP58058, then you want a Reese bracket kit. If he currently has a universal bracket kit, like our part # RP30439, then they will work with your truck. This kit works with virtually any truck however...
