A CURT gooseneck hitch is more than a necessary tool for towing; it is an integrated extension of your truck that allows you turn your 4x4 into the workhorse it was designed to be. Gooseneck hitches are stronger, tougher and more subtle than any other, and when quality craftsmanship and intelligent design become the fuel that drives a gooseneck hitch, you get a towing solution that leaves others lost for words. The CURT under-bed Double Lock EZr gooseneck hitch is strong, fast and easy to operate. It gets its name from the two locking pins that engage the trailer ball and hold it in place, giving you twice the security when towing especially heavy trailers. The Double Lock EZr mounts underneath your truck bed with compatible gooseneck installation brackets and provides a removable 2-5/16" gooseneck trailer ball with a gross trailer weight capacity up to 30,000 lbs. and a tongue weight capacity of 7,500 lbs. Using the heavy-duty operating handle, the trailer ball can be unlocked and flipped over whenever necessary to allow full use of the truck bed. For easy one-person installation, the Double Lock EZr comes with the CURT-exclusive center locator. This simple installation tool inserts into the gooseneck trailer ball hole during installation and shows exactly where to drill in the truck bed, eliminating errors and the need for meticulous measuring. The Double Lock EZr also comes with solid safety chain hookups, an attractive chrome trim ring, a durable A-coat finish and a limited lifetime warranty.

The hitch weight is 40 lbs. This refers to the weight of the hitch assembly itself, not the towing capacity. Do not exceed the recommended vehicle towing weight for your specific truck.
The hitch is designed to fit short bed models, but you must check for adequate turning clearance between the front of all trailers and the truck cab before towing. The manual specifically warns that short bed models require this clearance verification.
Yes, but 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. This check is especially important on two wheel drive models when hauling heavy loads.
Required tools: safety glasses, ear protection, ratchet, 8mm and 15/16" sockets, 8mm end wrench, drill, 3/16" and 5/8" drill bits, 4" hole saw, #3 Allen wrench, cutting fluid, and rust inhibitor. Optional: a small right angle drill and 3/4" step bit may ease installation, particularly when drilling over the exhaust.
The kit includes: two safety chain loop assemblies (60612-CLA), one 5/8"-11 x 2.50" x 3.25" U-bolt (60612-UB), four 5/8" wide washers, two U-bolt springs (CM-C113-UBS), two 5/8"-11 nylock hex nuts, two 3/8" washers, three M5 flat head countersunk cap screws, one M5 x 30mm hex head flange screw, and one M5 nylock hex nut.
Yes. The installation steps reference reinstalling the spare tire as the final step (step 11), indicating it must be removed during installation to access the truck bed for drilling and hitch assembly.
Possibly. The manual warns that brake, fuel, and electrical lines may need to be loosened or repositioned to provide clearance for new hardware. Check your specific truck model before installation. Some models may also require modification or removal of heat shields.
You will drill three holes: one 3/16" pilot hole from underneath the truck bed through the center locator/trim shield, two 5/8" holes for safety chain loops from underneath the truck bed (drilled over the exhaust), and one 4" hole from the top of the truck bed. The 5/8" holes should go through the low rib sections of the truck bed, not the high rib section.
Yes. Installation requires drilling a 3/16" pilot hole, two 5/8" holes for safety chain loops, and one 4" hole from the top of the truck bed. A right angle drill and 3/4" step bit are optional but may ease the process, especially when drilling over the exhaust.
Yes. The manual specifically recommends using cutting fluid to ease the process of drilling the 4" hole from the top of the truck bed.
1. Drill 3/16" pilot hole from underneath through the center locator/trim shield. 2. Drill two 5/8" holes for safety chain loops from underneath (through low rib sections). 3. Drill 4" hole from top of truck bed. 4. Deburr holes and spray with rust inhibitor; optionally insert rubber edging. 5. Place chrome ring and fasten with three flat head cap screws. 6. Place two U-bolts through the drilled holes. 7. From underneath, place washer, spring, washer, and nut on each U-bolt leg; tighten nuts until flush. 8. Insert cast lock pin into ball cylinder. 9. Insert handle from outside vehicle. 10. Slide washer and compression spring over handle, then insert handle rod into lock pin and secure with hex head flange screw and nylock nut. 11. Reinstall spare tire.
From underneath the truck, place a 5/8" wide washer, a U-bolt spring, another 5/8" wide washer, and a 5/8"-11 nylock hex nut on each of the four U-bolt legs. Tighten the nuts until they are flush with the bottom of the U-bolt.
Yes. The handle can be installed on the driver or passenger side, depending on your preference. However, some models may require you to use pliers to bend the metal flange below the bed outward to allow the handle to move without interference.
If needed, add or remove a 3/8" washer to ensure proper pull length of the lock pin. The washer is placed over the handle before inserting the handle rod into the lock pin.
The rubber cover is included in the parts list but the installation steps do not specify when or how to install it. The parts diagram indicates it is inserted when the ball is inverted. Refer to the specific instructions for your truck model or contact Curt Manufacturing for clarification on installation timing.
The manual does not provide a torque specification in foot-pounds or Newton-meters. It specifies only to tighten the nuts until they are flush with the bottom of the U-bolt. Contact Curt Manufacturing or consult a professional installer for the specific torque value.
The manual does not provide a torque specification for this fastener. It is used to secure the handle rod to the lock pin. Contact Curt Manufacturing for the correct torque value.
To unlock: pull the handle out as far as possible and rotate it clockwise. To lock: rotate the handle counter-clockwise until the locking pin snaps back into position. Never operate the vehicle with the handle in the unlocked position.
There should be a minimum clearance of 6" between the bottom of the trailer overhang and the top of the truck box sides.
Before towing the first time, verify: adequate turning clearance between the truck cab/box corners and trailer(s); minimum 6" clearance between the bottom of the trailer overhang and the top of the truck box sides; that the inverted ball will not interfere with the top of the differential when hauling heavy loads (especially important on two wheel drive models); that all hardware is torqued to proper specification; that trailer safety chain length has only enough slack to allow full turning without interference; and that trailer attachments to the safety chain loops are secure and cannot be shaken free.
Before towing every time: ensure all fasteners are tight and all structural components are sound (do not tow with worn or damaged parts); attach the trailer securely to both safety chain loops; ensure the handle is in the lock position and the locking pin passes completely through the ball and both walls of the hitch cylinder; ensure the trailer weight does not exceed any part of your towing system and that the load is heavier towards the front of the trailer without exceeding hitch tongue weight; ensure the trailer load is secured and centered left to right (never load heavier behind the trailer axle); check trailer tire inflation; and verify trailer lights, electric brakes, and breakaway switches are working properly.
No. Do not tow more than one trailer at a time. This may cause loss of control.
Vehicle performance (braking, handling, acceleration, turning radius) can be drastically affected by the trailer. Allow additional time and space for stopping, changing lanes, passing, and turning.
Keep the hitch ball, cylinder, and trailer coupler lubricated regularly using silicone spray or equivalent to prevent wear and rust. Keep the hitch assembly and trailer coupler free of dirt and other foreign debris. Periodically check that all fasteners are tight and all structural components are sound.
Verify: adequate turning clearance between the truck cab/box corners and all trailers; minimum 6" clearance between the trailer overhang and the top of the truck box sides; that the inverted ball will not interfere with the differential top when loaded and unloaded (critical on two wheel drive trucks); that all hardware is torqued to proper specification; that trailer safety chains have only enough slack for full turning; that trailer attachments to the safety chain loops are secure; and that the handle is in the lock position with the locking pin passing completely through the ball and both hitch cylinder walls.
The Curt 60611 fits truck beds on both short bed and standard bed models, and works on two wheel drive and four wheel drive trucks. However, you must verify turning clearance on short bed models and check differential clearance on two wheel drive trucks when loaded and unloaded.
You will need a drill with 3/16", 5/8", and 4" hole saw bits, ratchet with 8mm and 15/16" sockets, 8mm wrench, #3 Allen wrench, cutting fluid, rust inhibitor, safety glasses, and ear protection. A right angle drill and 3/4" step bit are optional but helpful.
Yes. You must drill a 3/16" pilot hole, two 5/8" holes for safety chains, and one 4" hole from the top of the truck bed. Drilling over the exhaust may require a right angle drill.
There must be a minimum of 6" clearance between the bottom of the trailer overhang and the top of the truck box sides.
Periodically check that all fasteners are tight and all structural components are sound. Before every tow, verify all fasteners are tight and do not tow with worn or damaged parts.
No. Do not tow more than one trailer at a time, as this may cause loss of control.
Some models may require you to use pliers to bend the metal flange below the bed outward to allow the handle to move without interference. This adjustment should be made during step 9 of the installation process.
Add or remove a 3/8" washer to ensure proper pull length of the lock pin. The washer is placed over the handle before inserting the handle rod into the lock pin during step 10 of installation.
If the groove on the ball and the pin in the cylinder are not aligned, simply rotate the ball until it drops into place. The groove must align with the cylinder pin for the ball to seat properly.
