I friend of mine gave me his bed rails and 5th wheel hitch for my 2008 Tundra,,, all I had to order was brackets and a hardware kit to install. This kit was all I needed to mount the rails to the brackets that came from etrailer. Once again, etrailer has my 100% support with their

I had understood this was a bolt/nut/spacer/washer assembly specifically for the brackets and the years of Toyota Tundra. If so, it should have come with two bolts (as opposed to stove bolts) for the front bolts on the front bed rail. Luckily, they were provided with the brackets (the only two rail bolts provided with the bracket kit. The position of the two front bolts for the front rail is too tight on the Tundra to be able to get any sort of wrench on the nut to give leverage to torque the bolt appropriately. But, you can install the bolt w/lock and flat washer from the underside and get a wrench on the bolt head and then torque the nut from above.

  • 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 Installation Kit for a 2006 Ford F-350 and Pro Series 15K Slider Hitch
    If the rails you received look like the ones for installation kit # RP30035 then all you will need is # RP30439. You can follow the linked instructions for RP30035. 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. I have linked a video showing an example installation of this kit for you.

  • Reese Custom Brackets Without Base Rails for 2015 Ford F-350 Super Duty
    Yes, we do have just the brackets available for your 2015 Ford F-350 that you can use with the Reese base rails, although the correct brackets are going to depend on which base rails you have because rails can be different lengths and will fit the brackets differently. If you aren't sure what you have, you can take a measurement, and I'll list the dimensions of the rails for you. - Reese Universal Outboard Base Rails # RP30153 measure 48" long x 7-1/2" wide x 1-7/8" tall and require...

If you happen to already have the base rails then you need the kit with the mounting brackets and hardware as part # RP30439.

    The two rail hardware kits # RP58504 and the # RP58430 basically fit the rail kits. One includes lock nuts ( # RP58430 ) whereas the # RP58504 does not. But both are listed as fits for same rail kits. Worth mentioning though is # RP58504 comes with Grade 8 bolts and # RP58430 comes with Grade 5.

  • Will Reese 5th Wheel Mounting Kit From 2016 Toyota Tundra Fit 2021 Toyota Tundra
    Assuming you are referring to the Reese Universal Base Rails and Installation Kit # RP30035-309, yes, this kit will fit in both a 2016 and 2021 Toyota Tundra. What you will need is new hardware to do this, the Replacement Hardware Kit for Reese 5th Wheel Base Rails # RP58504. That said, for a new truck I do recommend considering a no-drill mount kit so you do not have to drill into the frame of your 2021 Tundra. For that what you will need is the Reese Quick-Install Custom Installation...

  • Will Different Brand Brackets Work With Different Brand Fifth Wheel Rails?
    We do have some fifth wheel brackets that might fit with your Reese rails, but you shouldn’t use rails and brackets from different manufacturers. Most of the time the bolt holes don’t line up with each other. Instead, we have part # RP56018 which are Reese brackets that fit your 2019 Ram 1500. These are outboard brackets meaning they install on the outside of the truck’s frame rails and they fit rails that are 48 inches long. If your current rails are 48 inches long, then these will...

  • Brackets and Hardware Needed For Current 5th Wheel Base Rails on 2018 Ford F-250
    The Reese Quick-Install Custom Outboard Brackets for 5th Wheel Trailer Hitches # RP56017 is only a fit for the extended length base rails # RP30153 which are 48 inches long. The Replacement Hardware Kit for Reese 5th Wheel Base Rails - 10 Bolt # RP58504 will be needed in addition to the bracket kit. If you instead have the standard base rails which are 43 inches long # RP58058 then you will need the same replacement hardware kit # RP58504 but will instead use bracket kit # RP50074.

    We have just what you are looking for to install your current Reese rails and fifth wheel hitch in your 2004 Dodge Ram 3500.

  • 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.

  • 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...

    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.

  • 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...

    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.

    You can get just brackets and hardware without the rails for your 2014 GMC Sierra 1500.
