Experience powerful, reliable towing with the CURT PowerHaul™ Double Lock Gooseneck Hitch. Built for both professional haulers and weekend adventurers, this hitch delivers heavy-duty performance, making every towing job safer, smoother, and more controlled. Capable of handling up to 38,000 lbs. GTW and 9,500 lbs. vertical load with the included 2-5/16" ball and up to 40,000 lbs. GTW and 10,000 lbs. vertical load when paired with the optional 3" ball (#60694), the PowerHaul is ready for heavy trailers, construction equipment, and livestock transport. Installation is simple and designed for a single person, requiring no lowering of exhaust or spare tire, no welding, and no bed removal. The center locator system guarantees precise ball placement, so every hitching operation is safe, accurate, and worry-free. Security and convenience are at the forefront of the design. Double locking pins protect both the trailer and the ball, while the removable flip-and-store ball frees up truck bed space for gear, tools, or recreational equipment.

The CURT 60705 has a gross trailer weight (GTW) capacity of 40,000 lbs and a tongue weight (TW) capacity of 10,000 lbs. Never exceed your vehicle manufacturer's recommended towing capacity.
Required tools: ratchet, box-end wrench set, socket extension (6"), torque wrench, socket set, pry bar, rust inhibitor, hole saw (4"), drill bits (3/16" and 11/16"), and drill. A tools reference guide is available at curtmfg.com/trailer-hitch-installation.
Yes. You must temporarily lower the spare tire and heat shield. The installation also requires temporarily lowering the three rear-most rubber exhaust hangers. The rear axle breather hose may need to be temporarily relocated. No frame drilling is required.
Yes. You must drill a 3/16" pilot hole, four 11/16" holes through the truck bed, and one 4" hole from inside the truck bed. No frame drilling is required. Deburr all holes and spray exposed metal with rust inhibitor after drilling.
All 3/4" fasteners (hex bolts, washers, and hex flange nuts) must be torqued to 320 ft-lbs.
Safety glasses and ear protection must be worn at all times during installation.
Periodic inspection of the trailer hitch should be performed to ensure all mounting hardware remains tight and structural components are secure. Apply automotive grade grease to the guide slide and locking pin after installation.
The kit includes: one trailer hitch, one lock pin, one handle rod, one 2 5/16" ball, four 3/4" hex bolts (grade 8), four 3/4" serrated-flange nuts, four 3/4" flat washers, two 5/8" square U-bolts, eight M16 flat washers, four U-bolt springs, four 5/8" center lock nuts, one #10 nylock nut, one #10 flange bolt (grade 2), and U-edging.
The manual states that removal of the spare tire and spare tire heat shield may ease installation, but it is not listed as a required step. However, the three rear-most rubber exhaust hangers must be temporarily lowered, and the rear axle breather hose may need to be temporarily relocated.
You must drill three holes: one 3/16" pilot hole through the center locator, four 11/16" holes up through the truck bed using the safety chain holes in the gooseneck center section as a drill guide, and one 4" hole from inside the truck bed. The drill must be perpendicular to the cross member and bed. Use cutting fluid and cut slowly. Deburr all holes and spray exposed metal with rust inhibitor.
No. The installation requires no frame drilling. However, you must drill holes through the truck bed and use a 3/16" pilot hole through the center locator.
1. Lower the three rear-most rubber exhaust hangers. 2. Lift the gooseneck center section into position and secure with 3/4" hex bolts, washers, and hex flange nuts, torqued to 320 ft-lbs. 3. Drill a 3/16" pilot hole and four 11/16" holes through the truck bed. 4. Finish drilling the 4" hole from inside the truck bed. 5. Install U-bolts from inside the truck bed. 6. Install washers, springs, washers, and nuts on each U-bolt leg. 7. Pass the handle rod through the 1" round hole in the driver side frame rail and install the #10 flange bolt and nylock nut. 8. Snug all #10 fasteners and apply grease. 9. Reinstall exhaust hangers, heat shield, and spare tire.
Using a 5/8" open-end wrench, slide the wrench up to the rubber isolator, cradling the hanger rod. Place the flat edge of a pry bar between the wrench and the hanger stop or hanger rod. Rotate the pry bar toward the wrench to remove the rubber isolator. Using a lubricant or soapy water on the hanger rod and rubber isolator helps removal. This technique can be used if exhaust hanger removal pliers are not available.
From under the truck, lift the gooseneck center section into position with the center locator installed. Secure it with four 3/4" hex bolts (grade 8), four 3/4" flat washers, and four 3/4" serrated-flange nuts. Torque all 3/4" fasteners to 320 ft-lbs.
Install the two 5/8" square U-bolts from inside the truck bed, ensuring they sit flat in the lower position and slide easily without binding. Enlarge holes as needed for proper operation. Deburr holes and spray exposed metal with rust inhibitor. Then place a flat washer (M16), a spring, a flat washer (M16), and a center lock nut (5/8") on each of the four U-bolt legs. Tighten the nuts until flush with the bottom of the U-bolt.
Pass the handle rod through the 1" round hole in the driver side frame rail, just rear of the axle. Insert the handle rod into the linkage arm tube and install the #10 flange bolt and #10 nylock nut. Snug all #10 fasteners and apply automotive grade grease to the guide slide and locking pin. Make sure the handle operates properly and the locking pin can be pulled out, locked out, and re-engaged with the cylinder. If needed, adjust either the handle or linkage arm ¼" fasteners until operation is smooth.
The gooseneck center section is secured with four 3/4"-10 x 2" hex bolts (grade 8), four 3/4" serrated-flange nuts, and four 3/4" flat washers. All 3/4" fasteners must be torqued to 320 ft-lbs.
The handle rod is installed using one #10 flange bolt (1 1/4" long, grade 2) and one #10 nylock nut. These fasteners must be snugged but the manual does not specify a final torque value for #10 fasteners.
The manual does not mention any wiring or electrical connections for the CURT 60705. It is a mechanical hitch installation only.
The CURT 60705 has a gross trailer weight (GTW) capacity of 40,000 lbs and a tongue weight (TW) capacity of 10,000 lbs. However, you must never exceed your vehicle manufacturer's recommended towing capacity, which may be lower than the hitch capacity.
After snugging all #10 fasteners and applying automotive grade grease to the guide slide and locking pin, make sure the handle operates properly. The locking pin must be able to be pulled out and locked out, and then re-engage with the cylinder. If the handle does not operate smoothly, adjust either the handle or linkage arm ¼" fasteners until operation is smooth.
Periodic inspection should ensure that all mounting hardware remains tight and structural components are secure. This helps prevent damage to the product or vehicle.
Apply automotive grade grease to the guide slide and locking pin after installation. This ensures smooth operation of the handle and locking pin mechanism.
Yes. When finishing the 4" hole from inside the truck bed, use cutting fluid and cut slowly to ease the process. This helps prevent damage to the drill bit and produces cleaner holes.
After drilling and deburring all holes, spray exposed metal with rust inhibitor. This prevents rust and corrosion on the newly drilled surfaces.
The supplied U-edging can be installed if desired after drilling and deburring the 4" hole. It helps protect the edge of the hole and prevent rust.
Snug all #10 fasteners and apply automotive grade grease to the guide slide and locking pin. If the handle still does not operate smoothly, adjust either the handle or linkage arm ¼" fasteners until operation is smooth. Make sure the locking pin can be pulled out, locked out, and re-engaged with the cylinder.
Ensure the U-bolts sit flat when in the lower position. If they bind or do not slide easily, enlarge the holes as needed for proper operation. Deburr the holes and spray exposed metal with rust inhibitor.
Apply automotive grade grease to the guide slide and locking pin. Make sure the locking pin can be pulled out and locked out, and then re-engage with the cylinder. If it still does not operate properly, adjust either the handle or linkage arm ¼" fasteners until operation is smooth.
