ComeUp Utility Winch

This light-duty winch lets you pull ATVs, UTVs, boats, golf carts, and other small vehicles onto your trailer. The integrated design reduces installation time, and the compact size enables the winch to be mounted in most custom cabinets and boxes. The hard plastic external housing protects all the internal components from rain, rocks, and debris. It has an integrated LED panel that displays critical information about the winch and your vehicle's battery, and it has a cutoff switch that prevents the winch from draining your vehicle's battery. The winch also includes dual brakes to ensure reliable load-holding, a 50' synthetic rope with a fairlead that bolts directly to the winch body, and a circuit breaker that automatically cuts power to the winch if the motor begins to overheat.

Light-Duty, 1.7-Horsepower Motor

This winch features a 1.7-horsepower, 12-volt DC motor with 5,000 lbs of line pull. The permanent magnet motor offers the same line-pulling power and speed as a series-wound motor of comparable size, but it's lighter and uses less current.

Circuit Breaker

ComeUp Power Unit circuit breaker

There is an inline circuit breaker attached to the positive battery lead. It will interrupt the flow of power from the battery to the winch motor if the motor begins to overheat. When the internal elements of the circuit breaker have cooled it will automatically reset and you can use the winch again.

Sealed Contactor

ComeUp Power Unit with solenoid

The contactor - or solenoid - transmits power from the vehicle's battery to the winch motor. The 400-amp contactor - contained within the winch housing over the drum - is sealed to meet IP68 specifications for water and weather resistance. The copper terminals and carbon steel hardware are corrosion resistant.

ComeUp Utility Winch

A power disconnect button - or cutoff switch - shuts off the flow of power from your vehicle's battery to the winch. This prevents the winch from draining your vehicle's battery when it's not in use. Press the button to shut off power to the winch. Press it again to restore the power.

Free-Spooling Clutch

ComeUp Utility Winch

The free-spool clutch enables you to pull out the rope by hand. This saves battery power, prevents the brake from wearing down prematurely, reduces wear on the motor, and is much faster than waiting for the drum to unroll the rope.

The clutch is driven by a 3-stage planetary gear train. This provides more speed than traditional worm gear drives or 1- or 2-stage planetary gear trains.

Automatic, Load-Holding Mechanical and Dynamic Brakes

This winch includes a mechanical brake and a dynamic brake. This dual braking system provides a physical brake inside the drum and supplemental braking force generated by the winch motor. The 2 brakes operate simultaneously to ensure more reliable load holding when compared with single-brake trailer winches.

The automatic mechanical brake securely holds a load and prevents unintentional payout (or creep). When the winch motor is stopped, a large spring coil inside the drum expands to press against the spring chamber. The pressure of the spring on the wall of the spring chamber creates resistance that prevents the drum from rotating. This spring contracts when the winch is in gear to allow the drum to rotate.

When the winch is pulling the rope in or paying it out, the motor is not applying resistance to the drum. When you stop powering the rope in or out, the dynamic brake uses resistance from the motor to help hold the load.

Wireless, Waterproof Remote

ComeUp Utility Winch

The winch includes a wireless remote that lets you operate the winch from up to 90' away. The remote has a built-in LED that turns green when you are powering the rope in or out, turns red to indicate an overheated motor, and turns off when the winch is inactive. It has a 2-way digital signal that transmits at 2.4 GHz to prevent in-band interference.

ComeUp Utility Winch

There is a convenient pocket on the side of the winch to store the wireless remote.

ComeUp Utility Winch

There is also a rocker switch on the front panel that lets you power the load in and out directly from the winch.

Synthetic Rope

ComeUp Utility Winch

The synthetic rope made of Dyneema SK75 fiber that is lightweight yet stronger than steel. This synthetic rope is safer to use than a steel rope because it generates less kinetic energy - and therefore less kickback - if a break occurs. It won't stretch - or creep - over time like steel rope can. And it's also less likely to fray and create sharp strands so it's easier to handle and easier to spool.

The rope winds around a sealed, solid steel drum. The mounting flanges are strong enough to resist bending or breaking if the rope wrap becomes uneven and excess stress is put on the drum.

ComeUp Utility Winch

A hand-saver strap is included to use in conjunction with work gloves (sold separately) so that you can safely handle the rope and hook.

ComeUp Utility Winch

The hook is made of high-strength forged steel that is heavy duty and rust resistant. It has a spring-loaded safety latch for quick fastening and removal. The hook is permanently attached to a steel thimble on the end of the synthetic rope.

Hawse Fairlead

ComeUp Utility Winch

The cast aluminum hawse fairlead is designed to be used with synthetic rope. The fairlead has a black powder coat finish that resists corrosion, and it installs with stainless steel hardware. The fairlead hole is rounded to reduce friction on the rope when you're pulling it in and out. This helps reduce wear on the rope and keep it strong and functional.


ComeUp Utility Winch

This versatile winch can be mounted to your trailer in several different ways. The simplest way to install the winch is to bolt it directly to your trailer deck. This does not require a mounting plate or welding, but it does leave a footprint on the deck.

You can install a mounting plate (sold separately) on the front rail of your trailer and bolt the winch to the plate. This elevates the winch so it's easy to reach and frees up valuable space on your deck, but will require welding the mounting plate to the rail. You can also weld the mounting plate to the front bumper of the trailer to position the winch at deck level without infringing on valuable deck space.

The compact design allows the winch to easily fit into most custom cabinets or boxes. This keeps the winch out of the elements and keeps it hidden. Many cabinets and boxes can even be locked to protect the winch from would-be thieves. You can also install a dedicated battery inside or near the cabinet to power the winch. This prevents the winch from putting a strain on your vehicle's battery, and it eliminates the need to run a power lead all the way to the front of your truck.

Winch Line Pull Capacity

Layers of RopeCapacity (lbs)Total Rope on Drum (ft)
1st Layer5,0007.9
2nd Layer4,13617.4
3rd Layer3,52728.6
4th Layer3,07341.4
5th Layer2,72250

The line pull capacity of your winch is determined by the maximum load your winch can pull with a single layer of rope on the drum. As more layers of rope are wound onto the drum, pulling the same load requires more force, leading to a loss in winching power. With a 2nd layer of rope around the drum, your line pull capacity is reduced by approximately 14 percent. With 3 layers on the drum, the line pull capacity is reduced by approximately 23 percent, and with 4 layers on the drum it is reduced by approximately 35 percent.

Note: It is recommended that you begin any line pull with a minimum of 5 wraps and a maximum of 2 layers of rope on the drum.

Winch Capacity

There are a number of factors you must consider when determining the appropriate trailer winch for your application. You will need to know your gross vehicle weight, the angle and distance of the slope you will be pulling up, and whether the vehicle or object is static or rolling. The GVW is the stand-alone weight of your vehicle plus the weight of any items in and on the vehicle.

Rolling Load Winch Capacity

Percent InclineRolling Load Capacity (lbs)
Level Surface50,000
5 (3°)33,350
10 (6°)25,100
20 (11°)17,000
30 (17°)13,050
50 (26°)9,300
70 (35°)7,650
100 (45°)6,450

To calculate your winch's rolling load capacity - the amount of weight it can pull up an incline - you must multiply the line pull capacity by a factor determined by the degree of the incline.

The multiplication factors shown in the chart, right, include a 10-percent rolling friction factor.

Note: A 5-percent - or 3-degree - incline is a 1/2' rise over a 10' distance. Follow the chart to determine your winch's rolling load capacity.

Double-Line Pulling

Double-Line Pulling

Increase the pulling capacity of your winch by doubling up the rope with a pulley block (CU881080 - sold separately). Secure the pulley block to the vehicle you are pulling with a bow shackle (CU881092 - sold separately) to provide a strong anchor for your double-line pull. Using double-line operation will approximately double your winch's pulling capacity.

Review from a similar DV Series in Electric Winch

It came on time and was packaged great. I am using the winch to load my race cars into my enclosed trailer. It is working very well. It is slow enough to make loading safe but fast enough to not take all day. I am very pleased. 418430

It is a little over a year now of using my winch to load my cars. It is still working great. I have had only one issue that I think I caused, since it has never happened again.

Review from a similar DV Series in Electric Winch

This has been a great winch. We use it hard almost every day loading portable buildings. My only issues 1) I was led to believe it came with a remote control, it didn't 2) the hard wired control is giving us problems starting and stopping the winch. 466122

  • Correct Way to Connect a Breakaway Battery and Winch Battery to 12V Power on Trailer 7-Way
    A diode like the part # RM-690 is a great idea but the only issue is that is has a max load of 85 amps. A standard 5,000 lb winch, like the ComeUp DV-5000si # CU645010, will greatly exceed the 85 amp rating of the diode so it would be useless. What you will want to do is install a battery disconnect like part # BDW20247 (400 amps max), part # BDW20248 (500 amps), or part # DW05312 which completely disconnects them. You can then reconnect the batteries once you are connected to your tow...
