Caution: Please read through the instructions carefully. Installer is responsible for damage if instructions are not followed properly. Look behind each
drill or cut location BEFORE YOU DRILL OR CUT. Installer is responsible for
damage (i.e. drilling/cutting into a wiring harness, battery, fuel tank etc.).
Extra installers will be helpful in some parts of the installation. Please refer
to all torqueing specifications on page 2 for installation.
Note: You must install larger tires and wheels once the cart is lifted. Stock
wheels will not work. We recommend a 22” tire with a minimum of a 10”
offset wheel for use on the RHOX BMF Lift Kit.
4. Adjust the tow-in by loosening the
jam nut then lengthen or shorten
the tie rod by turning the hex
shaped rod adjustment. Shortening
the tie rods increases the tow-in,
lengthening decreases it.

5. Once camber and tow adjustments are finalized and set, tighten all
hardware and jam nuts.
6. Reinstall the front bumper using the
Original Hardware.
NOTE: Cowl and body were removed for visibility purposes in the photos
shown. The BMF lift kit can be installed with the cowl and body installed.
Installation Preparation (Front of the Cart)
1. Make sure the parking brake is engaged and the key is in the off
position.
2. Electric Carts Only: If your cart has a Tow/Run Switch, place switch
in the Tow position.
3. Remove the hub caps (if any). Loosen lug nuts
on both front wheels. Do not remove lug nuts.
4. Chock the back of the rear wheels to prevent
the cart from moving.
5. Using a jack, safely lift the front end of the cart enough to accommodate the additional height of the larger tires and wheels.
6. Place jack stands securely under the chassis and remove jack.
7. Fully remove the (8) front lug nuts, front tires and wheels. Discard
the tires and wheels as they will not be reused.

Adjust the Tow-In and Camber
1. Drive forward and back 20-40 feet to check the tow-in and camber
before making adjustments. Only make adjustments if needed.
NOTE: For stability, an 1/8” tow-in with a positive camber is recommended. This will level out when the cart is loaded.
8. Remove the front bumper by removing the (2)
bolts holding it in place. Retain bumper and
hardware.
9. Disconnect the tie-rod ends from the steering
knuckles by removing the safety pin and nut
from the tie-rod end. Retain hardware.
10. Remove the steering knuckles from the spindles by removing the safety pins, nuts and
bolts. Discard steering knuckles and hardware.
11. Remove the shock assemblies by removing the bolts connecting
them to the cross frame and the A-arm. Retain shock assemblies
and hardware.
12. Remove and discard the A-arms. Retain hardware.
2. Adjust the camber by changing the mounting
position of the shock in the shock tower.
Mounting the shock to the outside of the cart
will make the camber more positive. Mounting it
to the inside of the cart will make the camber
more negative.
3. Calculate the tow-in of the
front tires by measuring the
center-to-center distance of
the front of the front tires
versus the center-to-center
distance of the back of the
front tires. The front
measurement should be
1/8” shorter than the rear.
