READ BEFORE INSTALL:
It is generally a good idea to apply Loctite to all threaded bolts.
ALWAYS wear safety glasses and other approved safety gear when working on a vehicle.
All supplied bolts torqued according to chart at end of instruction.
It is recommended all installation be performed by a trained professional. Some modification may have
to be done.
Test brakes and verify no leakage in lines before driving. Recheck often. Removal or trimming
of factory plastic inner fender liner may be required to clear combinations of larger tire sizes
and wheel back spacings.
Professional alignment is recommended after install.
After alignment is complete and no additional adjustments are to be made to control arms. Torque all
1” Jam Nuts to 250 ft/lbs and all 1-1/4” Jam Nuts torque to 300 ft/lbs. Regularly check all jam nuts and
punch bolts on all control arms for proper torque/tightness. Failure to do so may cause premature
wear of threads on arms.

Safety Steps for installation
oFor installing EVO MFG products always use
wheel chokes to block rear tires from rolling.
oAlways make sure you have everything
necessary ready before install.
oIf you have to, carefully lift front of vehicle
by front frame rails extending suspension
until tires leave the ground, place frame on
approved jack stands for vehicle. Verify all
lines/wires are not over extended.
oRemove tires if needed for easier install.
oMake sure to wear safety equipment (eye
protection, hand protection, foot protection
etc.) at all times during installation.
oMake sure all safety precautions have been
taken.
oAlways check and replace any part of vehicle
that is warn or broken before starting install.
oDo not mix anything EVO with weaker
alternatives.
oIt is generally a good idea to apply liquid
threadlock to all bolts.
oTighten included hardware to torque
specifications in bottom table unless it is

FRONT INSTALL
1. Carefully lift rear of vehicle by
frame rails/crossmember extending
the suspension until the tires leave
the ground.
2. Securely place weight approved
jack stands for vehicle under frame
With vehicle rear tires now suspended
and frame securely supported on
stands, remove tires from vehicle.

7
1. Remove both driver and passenger side
swaybar links bolts at axle and swaybar
removing swaybar links and rotate sway up
and out of the way. Factory front links will
not be reused.
There is a 6mm allen key inside both driver
and passenger side upper sway bar studs. Use
allen head to allow nut to unscrew.
3. Remove bolt on brake line bracket.
4. Disconnect push-in clip from front
upper control arm mounts at axle
holding wire. Un clip all other
wires/hoses that are connected to
axle.
Vehicle wiring and hoses vary, make sure
all wires, hoses, lines etc. from frame to
axle are freed up giving ample length to
move axle downward as needed before
proceeding, verify wiring/hoses etc. do
not get stretched while lowering axle in
next steps.
Support BOTH axles with jack stands
5. IF you are replacing shocks and not using
shock extensions remove upper bolt.
Otherwise leave shock mounted at upper.
6. Lightly jack the front driver side axle tube
slightly. With axle slightly supported
remove front lower shock bolt from axle.
7. Repeat on passenger side.
Varying axle jack tension to the right
amount will alleviate load on the bolt and
allow it to freely slide out.

8
8. Remove trackbar bolt at both axles.
This will allow the axle to move side to side
so be cautious about this from here on.
9. Unbolt driveshaft from axle. Tie up and
out of the way.
10. To lower the axle without any binding, we
will remove the factory lower front
control arms. Remove the driver side
first, then remove the passenger side.
Repeat on rear arms.
Be careful when removing control arms. Axle
may rotate downward due to off centered
weight, support pinion if necessary.

9
11. Lower both front and rear axles (one at a
time) while checking wire and hose lengths
until springs can be removed.
Adjust wire and hose connections as needed.
12. Remove springs
13. Remove upper control arms from frame and
axle and set aside. Axle will be loose at this
time use caution and appropriate support.
Repeat on rear arms.
Be careful when removing control arms. Axle
may rotate downward due to off centered
weight, support pinion if necessary.
14. Carefully Support underside of gas tank.
Remove all bolts holding it to chassis.
Carefully lower tank (remember there is fuel
BE CAREFUL) until you can reach
connections on top of tank and disconnect.
Set tank aside in a safe well vented space
away from any flames/heat. It will be
reinstalled later.

10
15. Remove exhaust crossover bar from
chassis (small crossmember bar in front
of exhaust crossover), Bar will not be
reused. Keep hardware.
16. Using tools at your deposal,
grinders, cut off wheels, torch,
plasma cutter etc. Clearance all
control arm mounts, front
upper, lower and rear upper
and lower clean to frame rails.

11
17. At exhaust collector, remove bolt on
frame side of the collector and re-
install opposite way (from front to
back) through existing exhaust
flange nut, tighten to snug. On rear
side install supplied M8 nut.
18. Once all control arm mounts are
clearance clean to frame. Starting in
the front install front driver long arm
bracket to frame using the single
bolt hole on the underside of the
frame, where exhaust bar was once
bolted, using original factory bolt.
This will locate this bracket in the
proper location. Slight clearance of
edge/lip on exhaust collector may be
required. Do so as needed.
Repeat previous step on passenger side
(less exhaust note)
19. On driver side front only, lower arm
mounting hole will need to be drilled
through frame. Mark center using
bracket as template and drill through
both sides frame using a drill similar
in size to your hole saw centering
drill bit (~1/4” drill). Bracket may
need to be removed to drill. Be
careful to keep drill as square and
centered while drilling outer frame
material.

12
20. After center pilot hole is drilled on driver
side through both sides of frame DRILL
INSIDE HOLE ONLY with 5/8” drill
21. On outside of frame we need to make a
relief hole to install nut and washer
inside frame to newer lower control
arm bolt. Using at 1” or larger hole saw
and the previously drilled pilot hole
make hole in OUTSIDE of frame ONLY.
22. On rear, we need to trim some of the rear
body mount bracket on frame just rearward
of the body mount itself on
driver/passenger sides. Use the EVO Long
arm as a template and slowly trim and fit
body mount bracket until bracket fits nicely
against body mount bracket and lower hole
on underside of frame line up to install bolt.
Roughly the rear side of the body mount
will need to be full trimmed and cleaned to
frame ~1/2” rearward of body mount small
bolt.

13
Weld front Brackets as shown. (not all areas are
shown, weld all points of connection between
frame and brackets, top and bottom, front and
back)
Driverside: Red Lines for Reference
Passenger Side: Red lines for Reference

14
23. Remove body mount bolt that is
located in front of both rear tires.
Keep hardware, will be
reinstalling body mount.

15
24. Once all brackets are fitted to
frame and fitment is acceptable.
Clamp brackets to frame.
Tack then weld ALL SEAMS,
CONNECTIONS AND OPENINGS
BETWEEN EVO BRACKETS AND
FRAME.
25. Reinstall body mount using
factory hardware.
Avoid welding near transmission
crossmember on front passenger
bracket. Use picture as reference.
Pictured: Front passenger x2
Rear driver x2

16
With EVO MFG rear long arm bracket
located at frame, install upper control
arm gusset welding to body mount lip
and upper control arm bracket corner.
Reference red line when welding.
26. On rear axle, cleanly cut and grind
smooth to axle tube the entire
driver and passenger side rear
lower control/shock mounts.
Upper control arm mounts on axle
will stay unmodified.

17
27. Using the supplied EVO Rear
Lower Control Arm mounts for the
axle. Hold radius in bracket to
axle tube. Notched front edge of
EVO Bracket should be located
flush with outer edge of axle
bumpstop pad. Shock tabs should
angle toward middle of vehicle.
See photo.
Once positioned, tack in place. Verify correct location of left and right and weld all
connections to axle. Both sides.
Paint all bare surfaces.

18
28. After paint has dried. Install all
control arms into their new mounting
locations. Front upper arms will bend
giving clearance around frame. Rear
upper arms will bend giving clearance
for tire.
29. Install all control arms with adjustable
end at axle. All arms zerc fittings and
pinch bolts are recommend be on the
up side during install.
30. Arms fully threaded in will be just
slightly stretched of factory
placement. Some stretch can be done
by lengthening the arm thread out.
Do not exceed 1” total on all arms.
Cycle suspension to check for any
interferences.
ALL CONTROL ARM STARTING LENGTHS
ARE LISTED ON BEGINNING OF
INSTRUCTIONS.
