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 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD (except cab and chassis) (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 designed to be used in conjunction with CURT industry-standard 5th wheel base rails #16104 or #16204 (base rails sold separately).

Always verify your specific year, make, and model before ordering.
Yes, the CURT Custom 5th Wheel Brackets, Select Silverado, Sierra (Except Cab & Chassis) Fifth Wheel Trailer Hitch Bracket (Part #BKDK16411) is designed to fit the 2011-2019 Chevrolet Silverado 2500 HD.
The CURT Custom 5th Wheel Brackets, Select Silverado, Sierra (Except Cab & Chassis) Fifth Wheel Trailer Hitch Bracket (Part #BKDK16411) fits 2011-2019 Chevrolet Silverado 2500 HD models. The 2019 model year is the last year covered by this part number. For newer models, check for an updated version.
The CURT Custom 5th Wheel Brackets, Select Silverado, Sierra (Except Cab & Chassis) Fifth Wheel Trailer Hitch Bracket (Part #BKDK16411) Drilling is not required for installation. Typical installation time is . Basic hand tools are typically all you need.
Yes, the Curt 16411 is designed for GMC and Chevrolet 2500 & 3500 HD trucks. It fits both long box and short box configurations. The mounting rail positions differ by box length: long box is 52.375 inches from the rear edge of the truck box, and short box is 47.500 inches from the rear edge.
No. The manual states the system may not work with 2003 and earlier competitor products. If you are replacing or using an older competitor hitch, consult Curt technical support at 1-877-287-8634 before installation.
No, not without modification. The manual warns: do not install mounting rails over plastic bed liners. Plastic liners must be trimmed for metal-to-metal contact between the rail and truck bed. Spray-in liners are acceptable and do not require trimming.
Required tools are: ratchet, 3-inch and 6-inch socket extensions, torque wrench, crescent wrench, 3/4-inch box end wrench, 13mm, 24mm, 3/4-inch, and 15/16-inch sockets, drill, 1/8-inch and step drill bits, and safety glasses.
Yes. Step 2 of the installation requires removing the inner plastic fender liner by removing 4 screws and 3 plastic fasteners. This provides access to the frame rail for drilling and fastener installation.
The manual recommends removing the spare tire and fasteners from the heat shield to ease the process of tightening rear fasteners during step 8 of installation. This is not strictly required but is recommended for easier access.
Yes. The manual requires drilling 1/8-inch holes first to check alignment, then enlarging them to 9/16-inch using a step drill bit. The drilling locations are marked using a center punch based on the rail location diagram. The forward mounting rail uses the outermost holes; the rear mounting rail uses the second holes in from the outside.
Drill two sizes of holes: first, 1/8-inch holes to check alignment with the side plate slots. After confirming alignment, enlarge these holes to 9/16-inch using a step drill bit.
The kit includes: 10 bolts (1/2-13 UNC, 2-inch, Grade 8, part 10-10288), 4 bolts (5/8-11 UNC, 1-3/4-inch, Grade 8, part 10-10292), 4 M16 hex head cap screws (2.00 x 35mm, Grade 8.8, part 10-10403), 10 serrated flange nuts (1/2-13 UNC, Grade 8, part 20-00062), 4 serrated flange nuts (5/8-11 UNC, Grade 8, part 20-00105), 4 flat washers (5/8-inch, part 30-00131), 4 lock washers (5/8-inch, part 30-00132), 10 U-shaped spacers (0.313 x 1.00 x 2.00 inches, part CM-SP136), 10 square hole spacers (0.250 x 1.50 x 2.00 inches, part CM-SP33), 4 square hole spacers (0.375 x 1.25 x 2.50 inches, part CM-SP9), and 2 pieces of 5/8-inch fishwire. Not all hardware will be used.
Yes. The manual explicitly states: use only supplied fasteners for installation. Substituting fasteners may compromise safety and void the warranty.
Torque all 1/2-inch hardware to 110 ft-lbs. Torque all 5/8-inch hardware to 210 ft-lbs. Torque all M16 hardware to 136.7 ft-lbs. These specifications apply to the final tightening after all fasteners are in place.
The fishwire technique applies to 2015 and older models only. Fishwire 5/8-inch carriage bolts and CM-SP9 spacers through the access hole into position (as shown on page 1 of the manual). Leave fishwires attached and raise the side plate into position. Finger tighten the side plate to the side of the frame using 5/8-inch flange nuts. Repeat on the other side. For 2016 and newer models, use M16 bolts, 5/8-inch lock washers, and 5/8-inch washers instead.
Use a tape measure to center the mounting rail on the truck box floor at the proper distance from the rear edge: 52.375 inches for long box or 47.500 inches for short box. The forward mounting rail uses the outermost holes for drilling; the rear mounting rail uses the second holes in from the outside. After drilling and enlarging holes, fasten the mounting rail to the side plates using 1/2-inch carriage bolts with CM-SP33 and CM-SP136 spacers between the frame bracket and truck box to ensure metal-to-metal contact and prevent bed rib crush.
1. Place one mounting rail in the truck box, centered at the correct distance from the rear edge. 2. Remove inner plastic fender liner. 3. Mark and drill 1/8-inch holes using a center punch and rail location diagram. 4. Temporarily position side plates and check hole alignment. 5. Enlarge holes to 9/16-inch with a step drill bit. 6. Attach side plates to frame (fishwire method for 2015 and older; M16 bolts for 2016 and newer). 7. Fasten mounting rail to side plates with 1/2-inch carriage bolts and spacers. 8. Position the second mounting rail with the hitch product. 9. Repeat steps 3–7 for the second rail. 10. Torque all fasteners to specification.
Insert the tabs of the second mounting rail into the first mounting rail and push it tight towards the first rail. Ensure the second mounting rail is centered on the truck box floor. If more than one hitch product will be used with the mounting rails, both should be used at the same time to align the second mounting rail. This ensures that one product does not compromise the fit of the other.
Wear safety glasses during installation. Before installing the hitch, measure to ensure there will be enough clearance between the truck and trailer to allow for turns. Ensure the frame rail is clear of any electrical or brake components where side plates attach; move any components that may be trapped between the frame and side plates. Do not exceed the vehicle manufacturer's recommended towing capacity.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. This is a recurring maintenance task, not a one-time check.
Yes, the Curt 16411 fits GMC and Chevrolet 2500 & 3500 HD trucks in both long and short box configurations. It is not compatible with 2003 and earlier competitor hitch products.
Yes. Use only supplied fasteners for installation. Substituting fasteners may compromise safety and void the warranty.
Torque all 1/2-inch hardware to 110 ft-lbs, all 5/8-inch hardware to 210 ft-lbs, and all M16 hardware to 136.7 ft-lbs.
