AS-50x

Mounting bolts must be SAE grade 5 or better 

and torque to 17 ft. lbs.

Before you start to install this winch, 

disconnect the vehicle ground and positive 

leads from the battery.

This KFI 5,000 lb winch is designed with a bolt 

pattern that is standard in this class of winch. 

Many winch mounting kits are available that 

utilize this bolt pattern for the most popular 

ATV’s and UTV’s. You can find most of the 

ATV/UTV winch mounts on our Website 

www.kfiproducts.com

1.  Install the winch and fairlead with the  

supplied hardware per the instructions 

provided with the model specific mounting 

kit or prepare a flat, secure mounting 

location for the winch. 

Step 2-Mount the Contactor

1.  Find  a  location  for  the  contactor.    If  the 

Model specific mounting kit does not indicate 

a  recommended  contactor  location,  then 

it  is  recommended  that  the  contactor  be 

mounted close to the battery in a clean dry 

location.  Make sure the location you chose 

allows  sufficient  clearance  from  all  metal 

components.  Drill mounting holes if required.  

Once location is found do not install until all 

wiring is completed.

Step 3-

UTV Dash Mounted

Rocker Switch Kit

1.  Most UTV’s and SxS’s have predefined 

switch locations that are pre-scribed or 

marked for mounting and require finish cut 

with a knife.

2.  Use the cut-out dimensions shown below 

to cut-out the switch location If your dash 

doesn’t have the pre-scribed areas

3.  Once your switch is mounted you can route 

the wires back to where your contactor is 

located.

4.  Splice the end of the red wire to an ignition 

(keyed) controlled power source using the 

supplied wire splice.  You may need to use a 

test light to locate a suitable wire.  The wire 

should only have power when the key is in 

the ON position.

Installation

CAUTION

WARNING

2.  Attach the winch using the M8 x 25 or 30 

bolts and washers through the fairlead 

bracket or model specific mount and then 

into the winch. 

3.  Disengage  the  clutch  by  rotating  the  clutch 

cap  to  the  “RELEASE”  position.  Release 

the synthetic rope and pull through the roller 

fairlead.

4.  Attach the clevis hook and hand strap to the 

cable.

NOTE

If you chose not to use a model specific 

mounting kit, you will need to drill holes in the 

structural support of the vehicle.  Be certain 

that your structural support will stand up to the 

pulling forces of this winch.
