When you purchase a 5th wheel trailer hitch, you expect it to be capable of towing your RV, flatbed or whatever other 5th wheel trailer you own. While a 5th wheel hitch does offer an impressive amount of towing strength, it cannot get far without the proper installation equipment. Engineered for specific makes and models, CURT custom 5th wheel brackets provide the ideal solution for complementing the power of your 5th wheel trailer hitch. A custom 5th wheel bracket features a shape that contours to the frame of your truck and uses pre-drilled holes in the frame wherever possible to make installation quick and easy. Depending on your model of pickup truck, they also reduce or eliminate the need for drilling. These particular custom 5th wheel brackets offer a custom fit for certain model years of the Ford F-250 Super Duty, F-350 Super Duty and F-450 Super Duty (see application info to verify fitment). Finished in a durable liquid A-coat, CURT custom 5th wheel brackets are made to last. They include all necessary mounting hardware and are rated for up to 30,000 lbs. GTW when used in combination with CURT 40K base rails #16205 (also compatible with base rails #16104 or #16204; base rails sold separately).

The CURT 16432 5th Wheel Installation Brackets, Fits Select Ford F-250, F-350, F-450 Super Duty (Part #BKDK16432) fits 2017-2026 Ford F-250 Super Duty models. The 2026 model year is the last year covered by this part number. For newer models, check for an updated version.
Yes, the CURT 16432 5th Wheel Installation Brackets, Fits Select Ford F-250, F-350, F-450 Super Duty (Part #BKDK16432) is designed to fit the 2017-2026 Ford F-250 Super Duty.
The CURT 16432 5th Wheel Installation Brackets, Fits Select Ford F-250, F-350, F-450 Super Duty (Part #BKDK16432) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, the Curt 16432 is designed for Ford Super Duty trucks. However, the spacer configuration differs between model years: 2023 and newer models use a different bed support spacer (16431-SP-P) than 2022 and older models. Verify your model year before installation.
No. The manual states the system may not work with 2003 and earlier competitor products. If you plan to use multiple hitch products, consult Curt Manufacturing or use both products simultaneously during installation to ensure proper alignment.
Required tools: ratchet, 3/4" and 15/16" sockets, torque wrench, center punch, drill, 1/8" and 9/16" drill bits, and tape measure. A galvanic isolator kit is included with the product.
Yes. Lower and remove the spare tire and exhaust heat shield before installation to ease the process. These are reinstalled after the hitch is secured (Step 9).
Yes, drilling is required. The installation involves drilling 1/8" holes in Rows 1, 2, 3, and 4 of the bed, then enlarging them to 9/16". However, no frame drilling is required. If your truck has a plastic bed liner, it must be trimmed for metal-to-metal contact; spray-on liners are acceptable.
Torque in this sequence: (a) mounting rails to frame brackets: 110 lb-ft; (b) frame brackets to truck frame: 180 lb-ft. Fasteners in Rows 1 and 2 are initially installed loosely and tightened in this sequence during Step 8.
The hitch weight is 25 lbs. Do not exceed your vehicle manufacturer's recommended towing capacity when using this hitch.
No, not without modification. Plastic bed liners must be trimmed away to allow metal-to-metal contact between the mounting rails and the truck bed. Spray-on liners are acceptable and do not require trimming.
The package includes the mounting rail system, all fasteners listed in the hardware list (hex bolts, nuts, washers, spacers), and a galvanic isolator kit. The galvanic isolator kit is required for trucks with aluminum beds to prevent corrosion between steel and aluminum components.
Only if your Ford Super Duty has an aluminum bed. The manual states: "On vehicles with an aluminum bed, it will be required that all steel components be isolated from aluminum with the Galvanic Isolator kit supplied." The kit is included with the product.
Yes. Before installing the mounting rails and hitch, measure to ensure there is adequate clearance between the truck and trailer to allow for turns. This prevents interference during operation.
No. The manual explicitly states: "Use only supplied fasteners for installation." Using non-supplied fasteners may compromise the integrity of the installation and void the warranty.
The forward and rear mounting rails should be positioned 22" on center (center-to-center distance). This spacing is verified during Step 5b by measuring from the forward to rear rails and centering the rail side to side before drilling Row 3 and 4 holes.
Four types of spacers are used: (1) CM-SP136 (.313" x 1.00 x 2.00" U-shape) and CM-SP27 (.188 x 1.00 x 2.00" U-shape) are placed between the bracket/mounting rail and bed in Rows 1, 2, 3, and 4 to prevent bed collapse; (2) CM-SP34 (.188 x 1.50 x 3.00" round hole) is used under the center hole fastener; (3) CM-SP33 (.250 x 1.50 x 2.00" square hole) is used in Row 2; (4) 16431-SP-P (powdered spacer) is installed in bed support ends in Row 2 (2023+ models use different configuration than 2022 and older).
Temporarily install the side plates by placing four 5/8" hex bolts and washers through the side plates and through the holes in the frame rails, then secure with hex flange nuts. This allows you to mark hole locations with a center punch before drilling. The side plates are then removed, holes are drilled and enlarged, and the side plates are reinstalled permanently with carriage bolts and spacers.
Center punch marks are used to transfer hole locations from the side plates to the truck bed. In Step 2, you mark Row 1 locations, then place the rearward mounting rail to verify alignment. You then mark Row 2 holes and verify alignment with the center of the bed support. This ensures the mounting rails are correctly positioned before drilling.
Installation sequence: (1) Temporarily install side plates with 5/8" bolts to mark Row 1 and 2 hole locations; (2) Drill and enlarge Row 1 and 2 holes, reinstall side plates and rearward mounting rail with carriage bolts and spacers, loosely tighten; (3) Install Row 2 hex bolts and handle nuts loosely; (4) Position forward mounting rail with saddles/slider/goose, drill Row 3 and 4 holes; (5) Enlarge Row 3 and 4 holes, install forward mounting rail with carriage bolts and spacers, loosely tighten; (6) Install center hole carriage bolt with spacers; (7) Torque all fasteners in sequence: mounting rails to frame brackets (110 lb-ft), then frame brackets to truck frame (180 lb-ft).
Fasteners are installed loosely during Steps 3, 4, and 6 to allow for alignment and positioning of the mounting rails. All fasteners are tightened only in Step 8, after the forward mounting rail is positioned and all holes are drilled. This two-stage approach ensures proper alignment before final tightening.
Position the forward mounting rail by inserting its tabs into the already-installed rearward mounting rail and pushing it tight toward the other mounting rail. Ensure the mounting rail is centered between the box sides on the length of the truck bed floor. This positions the mounting rail correctly and ensures the 5th wheel has a snug fit. If using Step 5b (when hitch attachment is not available), place the forward rail 22" on center from the rear rail and center it side to side.
Step 5a is used when the 5th wheel saddles/slider/goose are available during installation—the forward mounting rail is positioned by inserting tabs into the rearward rail and pushing tight, which automatically centers it. Step 5b is used when hitch attachment is not available—you manually measure 22" on center from forward to rear rails and center the rail side to side before drilling. Both methods achieve the same final positioning.
Install a 1/2" x 1-3/4" carriage bolt in the center hole of the mounting rails. Place CM-SP27 and CM-SP136 spacers between the rail and the bed, and secure the bolt with a CM-SP34 spacer and 1/2" flange nut on the bottom of the bed.
Two drill bit sizes are used: 1/8" drill bits are used to create initial pilot holes in Rows 1, 2, 3, and 4 of the truck bed. These 1/8" holes are then enlarged to 9/16" using a 9/16" drill bit before installing the final fasteners.
No. The manual explicitly states "NO FRAME DRILLING REQUIRED" in the Install Notes. Drilling is only required in the truck bed (Rows 1-4), not in the frame itself.
When drilling holes, be aware of potential risks to vehicle components and use appropriate safeguards to protect them from damage. This is particularly important when drilling through the truck bed, as you may encounter wiring, fuel lines, or other components beneath the surface.
After tightening all fasteners to specification, reinstall the heat shield and spare tire that were removed in Step 1. Verify that all fasteners are tightened to the correct torque values (mounting rails to frame brackets: 110 lb-ft; frame brackets to truck frame: 180 lb-ft) and that the mounting rails are centered and secure before using the hitch.
Curt Manufacturing warrants the product to be free of defects in material and workmanship at the time of retail purchase by the original purchaser. If the product is found to be defective, Curt may repair or replace it at their option when returned prepaid with proof of purchase. Warranty is voided by alteration, misuse, or improper installation. Curt's liability is limited to repair or replacement and excludes incidental or consequential loss or damage.
If alignment issues occur, verify that: (1) The center punch marks in Step 2 correctly align with the rearward mounting rail in Row 1 and the bed support center in Row 2; (2) The forward mounting rail is centered between the box sides on the truck bed floor (Step 5a) or measured 22" on center from the rear rail (Step 5b); (3) All fasteners remain loose until Step 8 to allow adjustment. If using Step 5b, re-measure and re-center punch Row 4 hole locations before drilling to verify correct positioning due to bed support location variances.
Ensure that spacers are properly placed between the bracket/mounting rail and the bed before tightening bolts. The spacers (CM-SP136 and CM-SP27 U-shape spacers) distribute the load and prevent bed collapse. If collapse occurs, loosen the bolts, verify spacer placement, and retighten. Do not tighten fasteners without spacers in place.
Plastic bed liners must be trimmed away in the areas where the mounting rails will be installed to allow metal-to-metal contact between the rails and the truck bed. Spray-on liners do not require trimming and are acceptable. Trim the plastic liner before beginning installation to avoid interference with the mounting rails.
