Thank you for choosing FOX direct-replacement shocks for your vehicle. FOX products are designed, tested,
and manufactured by the finest professionals in the industry.
FOX recommends that you become completely familiar with the handling characteristics of your modified
vehicle before operating it under rigorous conditions, helping to avoid potential rollover situations and other
loss of control events. FOX further recommends that you use appropriate protective equipment at all times
when operating your vehicle.
To achieve the best performance and product longevity, periodic service and maintenance is required.

• FOX direct-replacement shocks are designed to fit and allow proper clearance with the stock
suspension. If aftermarket suspension components are installed it is the customer’s responsibility to
ensure that interference between the FOX shocks and other vehicle components does not occur at any
point in the shock stroke.
• FOX direct-replacement shocks should always be installed as a set for maximum performance.
• Proper installation and service procedures are essential for the safe and reliable operation of the
suspension components, requiring the experience and tools specially designed for this purpose.
Installation and maintenance procedures for this product must be performed by a qualified service
technician, to avoid potentially unsafe vehicle handling characteristics, which may result in SERIOUS
INJURY or DEATH.
• Modifying your vehicle’s suspension will change the handling characteristics of your vehicle. Under
certain conditions, your modified vehicle may be more susceptible to loss of control or rollover, which
can result in SERIOUS INJURY or DEATH. Thoroughly familiarize yourself with the modified vehicle
handling characteristics before any rigorous vehicle operation. Wear protective body gear and a helmet
when appropriate. Installation of vehicle roll bars or cage is highly recommended.
• FOX direct-replacement shocks are gas-charged and are highly pressurized. Placing shocks in a vise or
clamp, applying heat, or attempting to open or service the shock without the proper tools and training
can result in SERIOUS INJURY or DEATH. Do not attempt to modify, puncture or incinerate a FOX
direct-replacement shock absorber.
• Any attempt to misuse, misapply, modify, or tamper with any FOX product voids any warranty and may
result in SERIOUS INJURY or DEATH.
SAFETY INSTRUCTIONS
WARNING

605-01-278 4
• Always use a chassis lift for the installation of shocks, and make certain that the raised vehicle
is securely attached to the lift to prevent the vehicle from slipping, falling, or moving during the
installation process.
• DO NOT install any FOX product without the necessary special tools, expertise and chassis lift or you
will subject yourself to the risk of SERIOUS INJURY or DEATH. If you elect to not use a chassis lift
(which may result in SERIOUS INJURY or DEATH), ensure that the vehicle is: (1) on level ground, (2) that
all tires on the ground during installation are blocked to prevent vehicle movement, (3) that at least two
tires are on the ground at all times, and (4) that adequately secured jack stands are used to support the
vehicle. NEVER get under the vehicle until you have checked to ensure that the vehicle will be stable
during installation.
• FOX direct-replacement shocks are designed to fit your vehicle’s shock mounts without modification
except the reservoir placement on specific models and applications.
• If a preload adjustment is necessary for your application DO NOT adjust preload with the coil-over on
the vehicle. Remove the coil-over from the vehicle and use a spring compressor to remove the lower
spring hardware and spring. Once the spring is removed, you can adjust the preload ring. DO NOT
Exceed more the 1/2” of additional preload. If more than 1/2” of preload is required, you will need to go
up in spring rate or get a longer spring that fits the application.

the top and bottom of the tube. Use a corrosion
inhibitor (spray paint) to coat the exposed steel.
NOTICE: Some applications may require additional
cutting and trimming to attain proper jounce tube
length. The total length of the bump stop holder
should measure approximately 3.125” (Fig 2b).

11. Use the 3 supplied lock rings to install the bump
stop. The orange bump stop bearing cap must
protrude at least 1.75” from the cut line. Ensure the
lip on the lock ring goes into the OEM bump stop
tube (Fig. 6).
12. Apply medium-strength thread-lock to the
lock ring. Utilize all three lock rings per bump
stop. Tighten both the upper and lower lock
rings with the supplied spanner wrench. Use
the flat side of the third lock ring as a jam nut
against the lower lock ring (Fig. 5).
13. Repeat steps 1 through 12 on both sides of
the vehicle.
14. Set up and adjust the bump stops so the full
bump position does not bottom out on the shock,
or suspension components other than the bump
stop and bump tube. Depending on the application,
bump stop spacers may be required.
14. If bump stop spacers are used, the spacer must
be flat without any protruding hardware or large
recesses than could potentially damage the rubber
bump stop cap.
15. Reinstall coil springs and other previously
removed suspension components. Torque to OEM
specification.
16. Reinstall the wheels and torque to OEM
specification. Reconnect the battery.

FOX Factory, Inc., a Georgia corporation having an oce at 6634 Highway 53 Braselton, GA 30517 (“FOX”),
makes the following LIMITED WARRANTY with respect to its suspension products:
LIMITED ONE (1) YEAR WARRANTY ON SUSPENSION PRODUCTS.
Subject to the limitations, terms and conditions hereof, FOX warrants, to the original retail owner of each
new FOX suspension product, that the FOX suspension product, when new, is free from defects in materials
and workmanship. Unless otherwise required by law, this warranty expires one (1) year from the date of the
original FOX suspension product retail purchase from an authorized FOX dealer or from a FOX authorized
Original Equipment Manufacturer where FOX suspension is included as original equipment on a purchased
vehicle. If law requires a warranty duration of greater than one (1) year, then, subject to the other provisions
hereof, this warranty will expire at the end of the minimum warranty period required by such law.
This warranty is conditioned on the FOX suspension product being operated under normal conditions and
properly maintained as specified by FOX. This warranty is only applicable to FOX suspensions purchased
new from an authorized FOX source and is made only to the original retail owner of the new FOX
suspension product and is not transferable to subsequent owners. This warranty is void if the FOX
suspension product is subjected to abuse, neglect, improper or unauthorized repair, improper or
unauthorized service or maintenance, alteration, modification, accident or other abnormal, excessive, or
improper use.
Should it be determined by FOX in its sole and final discretion, that a FOX suspension product is covered
by this warranty, it will be repaired or replaced, by a comparable model, at FOX’s sole option, which will be
conclusive and binding. THIS IS THE EXCLUSIVE REMEDY UNDER THIS WARRANTY. ANY AND ALL OTHER
REMEDIES AND DAMAGES THAT MAY OTHERWISE BE APPLICABLE ARE EXCLUDED, INCLUDING, BUT
NOT LIMITED TO, INCIDENTAL OR CONSEQUENTIAL DAMAGES OR PUNITIVE DAMAGES.
This limited warranty does not apply to normal wear and tear, malfunctions or failures that result from
abuse, improper assembly, neglect, alteration, improper maintenance, crash, misuse or collision. This limited
warranty gives the consumer specific legal rights. The consumer may also have other legal rights which
vary from state to state or country to country. Some states and countries do not allow the exclusion or
limitation of incidental or consequential damages or warranties, and if dictated by law the above limitations
or exclusions may not apply to you. If it is determined by a court of competent jurisdiction that a certain
provision of this limited warranty does not apply, such determination shall not aect any other provision of
this limited warranty and all other provisions shall remain in full eect.
THIS IS THE ONLY WARRANTY MADE BY FOX ON ITS SUSPENSION PRODUCTS AND COMPONENTS, AND
THERE ARE NO WARRANTIES WHICH EXTEND BEYOND THE DESCRIPTION HEREIN. ANY WARRANTIES
