Choosing the right gooseneck hitch is only half the battle in preparing your pickup truck for towing a gooseneck trailer. CURT gooseneck hitches are a premium option in the heavy-duty towing industry, but they are only one of the members in the heavyweight tag team that is CURT gooseneck towing. While a gooseneck hitch gets all the glory above the floor of your truck bed, gooseneck installation brackets provide sure footing and a solid foundation for that oversized gooseneck trailer. Gooseneck installation brackets work by bolting onto the frame of your truck, typically using pre-existing holes. With a set of brackets firmly bolted on, a gooseneck hitch is able to be attached and is given the strength it needs to manage the massive amount of weight of a gooseneck trailer. With so many gooseneck hitch options available from CURT, we wanted to make sure we offered the gooseneck installation products needed to give you a complete towing package. Our installation brackets fit multiple vehicles and hitch heads. This particular set of gooseneck installation brackets is able to work with CURT Double Lock, Quick Goose II and under-bed folding ball gooseneck hitches. It is rated to the vehicle's maximum gross trailer weight capacity and provides a custom fit for certain years of the Chevrolet Silverado 1500 or 2500LD with classic body style, GMC Sierra 1500 or 2500LD with classic body style, Chevrolet Silverado 2500HD or 3500 or GMC 2500HD or 3500 (see application info to verify fitment). With each set of CURT gooseneck installation brackets, we provide the necessary hardware for an easier installation, and we coat our gooseneck brackets in a liquid A-coat to make sure rust and other potential damages are not a problem.

The 2010 model year is the last year covered by this part number. For newer models, check for an updated version.
Yes, the CURT Under-Bed Gooseneck Install Brackets, Select Silverado, Sierra 1500, 2500, 3500 Gooseneck Trailer Hitch Mount Kit (Part #BKDK60652) is designed to fit the 1999-2006 Chevrolet Silverado 1500.
The CURT Under-Bed Gooseneck Install Brackets, Select Silverado, Sierra 1500, 2500, 3500 Gooseneck Trailer Hitch Mount Kit (Part #BKDK60652) Drilling is not required for installation. Basic hand tools are typically all you need.
Yes, the C-652 subkit fits 99-07 Chevy/GMC 1500 & 2500LD Silverado/Sierra with classic body style, all bed lengths. Confirm your truck has the classic body style (not new body), as the 2500HD and 3500 models require the 01-10 version of the C-652.
Yes, the C-652 subkit is designed for all bed lengths on compatible Chevy/GMC Silverado and Sierra models. However, on short bed models, you must check for adequate turning clearance between the front of the trailer and the truck cab before towing.
Yes, the C-652 subkit fits 01-10 Chevy/GMC 2500HD & 3500 Silverado/Sierra with classic and new body styles, all bed lengths. Confirm your truck is a 2500HD or 3500 model, as the 2500LD requires the 99-07 version.
Yes, the C-652 is compatible with two-wheel drive trucks. However, you must perform a clearance check when the truck is both loaded and unloaded to verify that the inverted ball will not interfere with the top of the differential.
The manual specifies a 4-inch hole saw or a saber saw equipped with a metal cutting blade for drilling the truck bed. An overhead lifting device such as a chain falls, engine hoist, or cable come-a-long is recommended to lift the center section into place. Standard wrenches and sockets for 1/2-inch and 3/4-inch fasteners are required for assembly and torquing.
The subkit includes: two 1/2-13 x 4 1/8 x 6 3/4 x 1 1/2 SQ U-bolts (CM-1201-UBS), two 1/2-13 x 4 3/4 x 8 3/4 x 2 SQ U-bolts (CM-1202-UBS), twelve 1/2-13 x 1 1/2 hex bolts, twelve 1/2-inch lock washers, twelve 1/2-inch flat washers, two 3/4-10 x 2 1/2 hex head bolts, two 3/4-inch flat washers, two 3/4-10 hex flange nuts, four 1/2-13 hex flange nuts, four 2.50-inch diameter round hole spacers (CM-SP13), two round hole obround spacers (CM-C652-SP), one electrical box bracket (CM-EBB), two cable tie mounts (CM-11-CTM), and two cable ties (CM-116415-CT).
Yes, you must remove the spare tire before installing the C-652. The manual lists spare tire removal as the first step in the installation process.
The heat shield under the truck bed floor must be removed or a section cut out for the hitch assembly. Specifically, remove the heat shield from in front of the back crossmember, and remove the heat shield from the back of the crossmember located near the front of the wheel well. All models require modification or removal of heat shields.
Possibly. The manual warns that brake, fuel, and electrical lines may need to be loosened or repositioned to provide clearance for new hardware. You should inspect these lines during installation and reposition them as needed to avoid damage or pinching.
Measure from the tailgate end of the truck bed (hook the tape measure over the back of the truck box, not from the edge of the tailgate). For 1 ton long bed, measure 50 7/8 inches. For 1500 & 2500 short bed, measure 44 1/4 inches. For 1500 & 2500 long bed, measure 49 1/2 inches. Mark the center between the wheel wells. This marks the center point for the drill hole. If the truck has a spray-on bed liner, add 1/8 inch to 3/16 inch to the measurement. This hole location is critical for correct installation and will position the ball 4 to 6 inches in front of the axle.
Make a 4-inch hole using a 4-inch hole saw, or by making a 4-inch circle and cutting it out with a saber saw equipped with a metal cutting blade. Measure, mark, and saw carefully, as this hole location is critical for correct installation.
You may drill through both the bed liner and truck bed, but it is more difficult to accurately locate the midpoint between the wheel wells and to keep the bed liner from moving while cutting the hole. If you have a spray-on bed liner, add 1/8 inch to 3/16 inch to the measurement when locating the hole.
Yes, if desired, you may trim the sideplate U-bolt after installation completion to provide additional handle rod clearance.
An overhead lifting device such as a chain falls, engine hoist, or cable come-a-long is recommended but not required. It can be used to lift the center section into place by lowering a loop of rope or chain through the hole in the truck bed floor and attaching it to the round hitch receiver tube. The lifting device should be disconnected before squaring the center section across the frame, installing the sideplates, and torquing fasteners.
1. Remove spare tire and heat shields. 2. Mark and drill the hole in the truck bed. 3. Install the rear crossarm between the frame and truck bed floor. 4. Install the front crossarm between the frame and truck bed floor. 5. Install the center section, inserting bolts finger tight into both crossarms. 6. Install the sideplates with large holes toward the back. 7. Attach sideplate flanges to crossarms with finger-tight bolts. 8. Attach sideplates to the truck frame using U-bolts and 3/4-inch hex bolts, finger tight. 9. Torque all fasteners in the specified order. 10. Optionally trim the sideplate U-bolt.
Slide each crossarm between the frame and truck bed floor above the passenger side rear tire. After spanning the frames, rotate the crossarm vertically with the holes towards the bottom. On 1 ton applications, slide the crossarm through toward the front of the third truck bed rail. Before installing, run a 1/2-13 bolt or 1/2-13 tap through the crossarm holes to remove any powder or debris.
Carefully raise the center section above the fuel tank from beneath the truck. Insert four 1/2 x 1 1/2-inch hex bolts with a washer and lock washer through each of the slots on the inside of the center section, and thread them finger tight into the rear crossarm. Repeat for the front crossarm. Be sure the round hitch cylinder that protrudes from the top of the center section is positioned toward the rear of the truck and fits into the hole in the truck bed.
Install the sideplates with the large holes toward the back of the truck, aligning them with the existing slot in the frame. For 07 and up 2500 & 3500 new body styles, remove the electrical box on the inside of the driver side frame and attach it using the supplied electrical box bracket, attaching the bracket to the frame with the 3/4-inch bolt used to attach the sideplate and using the obround spacers to fill the slot in the frame.
Attach the sideplate flanges to the crossarms using two 1/2 x 1 1/2-inch hex bolts with 1/2-inch washers and 1/2-inch lock washers. Thread them through the inside of the sideplate flanges into the crossarms. Keep them finger tight only until the final torque step.
For 3/4 ton and 1 ton applications, use the large U-bolt (CM-1202-UBS, 1/2-13 x 4 3/4 x 8 3/4 x 2 SQ). For 1/2 ton and 3/4 ton light duty trucks, use the smaller U-bolt (CM-1201-UBS, 1/2-13 x 4 1/8 x 6 3/4 x 1 1/2 SQ).
Position the U-bolt from the inside of the truck frame, being careful not to damage or pinch the wiring harness or brake lines. Attach to the sideplate using two 1/2-inch flange nuts, finger tight only. Attach the rear section of the sideplate to the frame using a 3/4-inch hex bolt and 3/4-inch washer through the sideplate and frame. Finger tighten a 3/4-inch flange nut to the bolt on the inside of the frame. For 3/4 and 1 ton heavy duty trucks, use the bottom hole on the sideplate. For 1/2 ton and 3/4 ton light duty trucks, use the top hole on the sideplate.
Torque all 1/2-inch fasteners to 110 ft-lbs and all 3/4-inch fasteners to 380 ft-lbs. When torquing the U-bolts, tighten them slowly, alternating between the top and bottom of the U-bolt until equally tightened to a maximum of 40 ft-lbs.
Torque in the following order: First, torque the center section to the front and rear crossarms. Second, torque the sideplates to the truck frame on both sides (when torquing the U-bolts, tighten them slowly alternating between the top and bottom until equally tightened to a maximum of 40 ft-lbs). Third, torque the sideplate flanges to the front and rear crossarms.
Do not exceed the recommended vehicle towing weight. The manual does not specify a weight limit; refer to your vehicle manufacturer's recommended towing capacity.
Yes, you must remove all rear window accessories before towing.
On two-wheel drive trucks, a clearance check must be performed when the truck is both loaded and unloaded to verify that the inverted ball will not interfere with the top of the differential.
Use the clearance calculation formula on page 4. Measure the distance from the cab to the ball center (X), subtract half the trailer width (Y), and subtract any coupler overhang (W) if applicable. If the result (Z) is positive, the trailer will not interfere with the cab. If negative, the trailer will interfere. The manual provides example calculations and a worksheet to complete before towing.
After installation, periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. Before each use, check for proper torque on all nuts and bolts and check for excessive wear.
Maintenance is required every 30 days or prior to use: 1. Keep the hitch ball lubricated regularly using silicone spray or equivalent to prevent wear and rust. 2. Keep the hitch assembly free of dirt and other foreign debris. 3. Check for proper torque on all nuts and bolts before each use and check for excessive wear. 4. Check ball wear before each use. Do not tow a trailer with worn or damaged parts.
The manual does not specify whether the C-600 gooseneck ball is included. The parts list and installation steps reference the C-600 and note that gooseneck hitch installation and operation procedures are covered in separate C-600 instructions. Contact Curt Manufacturing or your retailer to confirm what is included in your purchase.
The C-34 is a separate component that relocates the OEM vacuum canister to a new location 5 to 6 inches lower than the original location to provide clearance for the C-652 hitch installation. It includes one cable tie mount and two cable ties. The canister is repositioned using cable ties attached to the fuel tank strap.
The manual does not specify whether the C-34 is required for all C-652 installations or only for certain vehicles. The C-34 instructions are included in the manual, suggesting it may be needed for some applications. Contact Curt Manufacturing or your retailer to confirm whether the C-34 is required for your specific truck.
The C-652 fits 99-07 Chevy/GMC 1500 & 2500LD Silverado/Sierra (classic body, all beds) and 01-10 Chevy/GMC 2500HD & 3500 Silverado/Sierra (classic and new body, all beds). Confirm your model year, truck series, and body style.
You need a 4-inch hole saw or saber saw with metal cutting blade, an overhead lifting device (chain falls, engine hoist, or come-a-long) is recommended, and standard wrenches/sockets for 1/2-inch and 3/4-inch fasteners.
Yes, you must drill a 4-inch hole in the truck bed at a specific location (measured from the tailgate: 50 7/8 inches for 1 ton long bed, 44 1/4 inches for 1500 & 2500 short bed, or 49 1/2 inches for 1500 & 2500 long bed). This hole is critical for correct installation.
Yes, you must remove or modify heat shields. Remove the heat shield from in front of the back crossmember and from the back of the crossmember near the front of the wheel well. All models require modification or removal of heat shields.
Torque all 1/2-inch fasteners to 110 ft-lbs and all 3/4-inch fasteners to 380 ft-lbs. U-bolts should be tightened slowly, alternating between top and bottom, to a maximum of 40 ft-lbs.
Remove all rear window accessories, verify the trailer will not interfere with the truck cab using the clearance calculation on page 4, and on two-wheel drive trucks, check that the inverted ball will not interfere with the differential when the truck is loaded and unloaded.
Maintenance is required every 30 days or prior to use: lubricate the hitch ball with silicone spray, keep the assembly free of dirt, check all fasteners for proper torque and excessive wear, and check ball wear. Do not tow with worn or damaged parts.
Use an overhead lifting device such as a chain falls, engine hoist, or cable come-a-long to lift the center section into place. Lower a loop of rope or chain through the hole in the truck bed floor and attach it to the round hitch receiver tube in the center section. Maintaining upward pressure may facilitate fastening the crossmember to the center section, especially if the truck bed floor has been distorted downward from heavy use.
Measure from the tailgate end of the truck bed by hooking a tape measure over the back of the truck box (do not measure from the edge of the tailgate). Use the correct distance for your truck: 1 ton long bed = 50 7/8 inches, 1500 & 2500 short bed = 44 1/4 inches, or 1500 & 2500 long bed = 49 1/2 inches. Mark the center between the wheel wells. If the truck has a spray-on bed liner, add 1/8 inch to 3/16 inch to the measurement. This hole location is critical for correct installation.
Before installing the crossarms, run a 1/2-13 bolt or 1/2-13 tap through the crossarm holes to remove any powder or debris. This ensures proper fastener fit and function.
Use the clearance calculation formula on page 4. Measure the distance from the cab to the ball center (X) and subtract half the trailer width (Y). If the trailer has a coupler overhang (W), subtract that as well. If the result (Z) is positive, the trailer will not interfere. If negative, the trailer will interfere with the cab. The manual provides example calculations and a worksheet.
On two-wheel drive trucks, you must perform a clearance check when the truck is both loaded and unloaded to verify that the inverted ball will not interfere with the top of the differential. If interference is detected, the hitch may not be suitable for your truck or may require repositioning.
