Caution:
This vehicle will require a professional wheel alignment after this lift kit has been
installed. Failure to have this vehicle professionally aligned could result in poor
vehicle handling, and braking; as well as excessive tread wear. Headlight
alignment will also be affected and will need to be adjusted. Further, certain
aspects of this installation can be dangerous. Therefore, we recommend that a
trained professional technician install this kit.
General Note
The photographs for these instructions were taken with
the vehicle placed on a twin post lift. This allowed for a
clearer view and better pictures. However, these
instructions are written to be used with a floor jack and
jack stands to accommodate the majority of our
customers. We also used power tools in these
instructions but, manual tools can easily be substituted
and work very well.
Step 1
Lift the front of the vehicle with a floor
jack and support it with (2) jack stands.
Refer to Figure 1 for proper floor jack
and jack stand support positions.
Figure 1
Caution:
It is extremely dangerous to perform any work on a vehicle raised on a jack alone,
even for work that can be finished quickly. Jack stands must be used to support the
vehicle.
Trim
Step 2
Step 3
Remove the 2 front wheels and set them
aside.
Remove the (3) trim to skid plate bolts
using a 10 mm socket.
Hook
Skid

Step 4
Tech Tip
Remove the skid plate by removing (3)
bolts using a 12 mm socket.
The skid plate is hooked to the frame in
the front on some models. After the bolts
have been removed, lift the skid plate
and shift it toward the drivers side to
unhook it.
Sway

Bolts
Sway Bar
Link
Step 5
Step 6
Disconnect the driver side sway bar link
from the lower control arm using a 19
mm socket. Repeat this step on the
passenger side sway bar bar link.
Using a 17 mm socket, LOOSEN the (2)
forward bolts and REMOVE the (2) rear
bolts.
Note: The forward bolt holes are slotted,
doing away with the need to remove the
bolts.
Sway
Bar
Step 7
Remove the sway bar by sliding it
rearward and then down.
Step 8
Set the sway bar aside.
Begin on the driver’s side wheel.
Front Lower Control
Arm Eccentric
Lock Bolt
Rear Lower Control
Arm Eccentric Cam
Step 9
Step 10
Mark the position of the front lower
control arm eccentric cam with a
permanent marker as shown. We used
“white out” but any light colored marker
could be used.
Mark the rear lower control arm
eccentric cam as shown, like what was
done in step 9.
Note: This step is done so the eccentric
cams can be returned to their original
position keeping the alignment as close
as possible to factory spec for your trip
to the alignment shop.
Rear Lower Control
Arm Lock Nut
Step 11
LOOSEN the FRONT lower control arm
eccentric lock bolt (See Step 9 for
illustration) using a 22 mm socket. Do
not remove the lower control arm
eccentric cam.
Note: It may be necessary to hold the
eccentric cam with an adjustable end
wrench while loosening the lock bolt.
Step 12
Repeat Step 11 on the rear lower control
arm eccentric by LOOSENING the lock
nut. Do not remove the eccentric cams.
Note: It may be necessary to hold the
other end of the bolt with a wrench while
loosening the lock nut.
Steering Knuckle
Strut
Lower Control
Arm
Step 13
Step 14
Remove the (2) lower ball joint bolts
using a 24 mm socket. This will detach
the lower control arm from the steering
knuckle.
Begin detaching the strut from the lower
control arm by removing the nut as
shown. Use a 24 mm socket.
Strut
Note: It may be necessary to hold the
other end of the bolt with a wrench.
Lower Control
Arm
Step 15
Then detach the strut from the lower
control arm by removing the bolt. Notice
the orientation of the bolt. It will need to
be installed from the same direction.
Note: It may help to lift slightly on the
control arm while removing the bolt.
Caution: Avoid damaging the threads
on the bolt. The bolt will be needed for
reassembly.
Step 16
Let the lower control arm swing down
out of the way.
Spacer
Strut Mount
Flange Nuts
Arrows
Step 17
While holding the strut with one hand,
remove the (4) upper strut mount flange
nuts using a 14 mm socket. Then guide
the strut out of the bottom where the
lower control arm was.
Step 18
Install the supplied spacer on top of the
strut. Be sure to align the arrows as
shown.
Caution: Be careful not to damage the
CV Boot if you are working with a 4WD
model Tundra.
Caution: The fit between the spacer and
strut is a very close tolerance. It may be
necessary to tap the spacer into place
with a dead blow or plastic tipped
hammer.
Step 19
Tech Tip
Install the factory
flange nuts securing
the spacer to the strut
and torque the nuts to
47 ft. lbs. in the pattern
shown to the right.
Some have found it helpful to place a
pry bar through the lower strut bushing
to hold the strut while tightening the
spacer flange nuts.
Step 20
Step 21
Install the strut back in the vehicle
opposite the way it came out and install
(BUT DO NOT TIGHTEN) the (4) strut
mount flange nuts supplied in the kit.
Because the strut is rotated 1/8 of a turn
from its original position, it will be
necessary to rotate the lower part of the
strut. This will take a fair amount of
force. This is best accomplished by
inserting a large screwdriver or pry bar
in the strut bushing and twisting the strut
until the bushing aligns with the lower
strut mount. (See next picture)
Note: This strut will only install in one
position. The best indicator that the
strut is installed correctly is if the “Low
Range Off-Road” label is facing you.
Lower Strut
Mount
Lower strut being properly aligned
with the lower strut mount.
Step 22
Position the lower strut bushing in the
lower strut mount and insert the bolt.
Step 23
Step 24
Install the nut on the lower strut
mounting bolt and while holding the bolt,
torque the nut to 144 ft. lbs.
Align the ball joint to the steering knuckle
and install the front bolt.
Note: Some SR5 models with aluminum
skid plates may not work with the
supplied skid plate spacers. In these
cases install the skid plate without the
spacers.
Note: It may be necessary to lift on the
bottom of the control arm with a floor jack or
under hoist jack stand to get these two parts
to align.
Caution: Be careful here. These bolts are
easily cross-threaded.

Step 52
Lower the the drivers side of the rear
axle assembly until there is about a 2”
gap between the rear axle assembly
and the leaf spring.
Step 53
Orient the supplied aluminum block with
the locater pin facing down and the “F”
toward the front of the vehicle.
Note: It may be helpful to LOOSEN (but
do NOT remove) the passenger side Ubolt plate nuts to obtain the needed
clearance.

Caution: Do not lower the axle too
much or the emergency brake cable
could become kinked.
Locater
Hole
Locater pin
Step 54
Place the aluminum block as shown and
raise the axle back up making sure the
hole in the block aligns with the locater
pin in the leaf spring.
Note: Some have found it helpful to use
a ratcheting binder strap connected
between the differential and leaf spring
to assist in aligning the pin and the hole.
Step 55
Place the bump stop on top the leaf
spring and install the supplied longer Ubolts as shown.
Note:
Make sure the bump stop is
positioned properly on top the leaf
spring.
Step 57
Step 56
Repeat Steps 50 through 56 on the
passenger side of the rear axle
assembly.
Install the factory U-bolt plate, with the
supplied washers and nuts. Tighten the
nuts just enough to keep all the parts in
place, but do not tighten them all the
way yet. It will help the positioning of
the passenger side components if the
nuts are left loose for now.
Step 58
Torque the U-Bolt nuts 105 to 110 ft. lbs.
on the the passenger side. Torque the
nuts on the driver side to the same
specification.
Step 59
Reconnect both shock absorbers and
torque the nut to 66 ft. lbs.
Note: To assist in aligning the shock
absorber and mount, you may need to
lift the rear axle assembly a little with a
floor jack.
Step 60
Check all emergency brake cables, ABS
wires, brake lines and brake hoses to
see that they are properly routed. It
may be necessary to bend some
brackets slightly to better position them.
Also, check to see that all fasteners are
tight and properly torqued. This will
insure that nothing has been left loose.
Loose fasteners could result in vehicle
damage, serious accident and
personal injury.
Step 61
Reinstall the rear wheels and torque the
lug nuts.
Note: Factory wheel lug nut torque is 97
ft. lbs. for aluminum wheels and 154 ft.
lbs. for steel wheels.
Congratulations:
Step 62
Raise the rear of the vehicle as before
with the floor jack. Remove the jack
stands and lower the vehicle to the floor.
