Important information that needs to be read before
installation begins:
Choosing a tire and wheel combination is an important
step to make sure that you have a proper fit. For part #
56070, an 18” wheel or larger must be used once the
suspension system has been installed. If using a 18”
wheel, it is not recommended to exceed 9” in the width
of the wheel and also the backspacing must be 5 1/2”
or less. If using a 20” wheel, it is not recommended to
exceed 9” in the width of the wheel and also the backing spacing must be 6” or less. Tuff Country recommends a 35x12.50 tire package. If larger than a
35x12.50 tire is installed on your vehicle in conjunction with part # 56070; Tuff Country assumes no liability and the warranty will be VOID. Slight trimming or
removal of the front inner mud flaps may be nessecary
for proper clearance.
Tuff Country EZ-Ride Suspension recommends a wall
mounted strut compressor be used when performing
the steps that talk about installing the pre load spacer
into the strut. If you do not have a wall mounted strut
compressor, please have these steps performed by
your local Toyota Dealership.
Before installation begins, Tuff Country EZ-Ride
Suspension highly recommends that the installer
performs a test drive on the vehicle. During the test
drive, check to see if there are any uncommon sounds
or vibrations. If uncommon sounds or vibrations occur
on the test drive, uncommon sounds or vibrations will
be enhanced once the suspension system has been
installed. Tuff Country EZ-Ride Suspension highly
recommends notifying the customer prior to
installation to inform the customer of these issues if
they exist.
New longer rear shocks are needed after this suspension system has been installed and the rear shocks
need to be ordered as a separate part #. If you have not
already ordered your rear shocks, please feel free to
contact Tuff Country or your local Tuff Country dealer
and order your new rear shocks. Tuff Country recommends installing a 30” fully extended nitrogen gas
shock in the rear.
Tuff Country EZ-Ride Suspension packages (2) sets of
instruction sheets with this box kit. (1) is for the
installer and (1) is for the customer. The (1) for the
customer has some post installation procedure
literature and it is the installers responsibility to make
sure that the customer receives a copy of the
installation manual along with the literature.

Front end installation:
1. To begin installation, block the rear tires of the vehicle so
that the vehicle is stable and can’t roll backwards. Safely lift
the front of the vehicle and support the frame with a pair of
jack stands. Place a jack stand on both the driver and the
passenger side. Next, remove the front wheels and tires
from both sides.
2. Remove the stock front upper skid plate from the stock
location. The (2) stock lower bolts and (2) stock upper bolts
need to be saved for later re-installation. The (3) stock
upper mounting hardware that connects the skid plate to
the plastic valence and the skid plate can be discarded.
3. Working on the driver side, remove the stock sway bar
from the stock lower control arm. Save the stock hardware.
Repeat procedure on the passenger side.
4. Working on the driver side, remove the stock sway bar
from the stock frame mounting location. Save the stock
hardware. Repeat procedure on the passenger side. Set
the stock front sway bar aside.
5. Working on the driver side, remove the stock cotter pin
from the stock castle nut that connects the outer tie rod to
the stock knuckle. Save the stock cotter pin. Now, loosen
but do not remove the stock castle nut that connects the
outer tie rod to the stock knuckle. Carefully break the stock
taper. Special note: Hitting the stock knuckle with a
hammer will make removal of the stock outer tie rod
easier. Take special care not to rip or tear the stock
outer tie rod ball joint dust boot. Repeat procedure on
the passenger side.
6. Working on the driver side, remove the stock ABS line
and brake line brackets from the stock location on the
knuckle and the upper control arm. Save all mounting hardware. Repeat procedure on the passenger side.
7. Working on the driver side, remove the stock brake
caliper from the stock location. Save the stock hardware.
carefully tie the stock brake caliper up out of the way in the
fender well. Take special care not to over extend the
brake lines or ABS lines. Repeat procedure on the passenger side.

the stock location and set aside. Repeat procedure on the
passenger side.
11. Working on the driver side, remove the stock cotter pin
that attaches the stock upper control arm castle nut to the
stock knuckle and set aside. Now, loosen but do not
remove the stock castle nut from the upper control arm ball
joint. Carefully break the stock taper on the upper control
arm ball joint and the knuckle. Repeat procedure on the
passenger side.
12. Working on the driver side, remove the (2) stock bolts
that connect the stock lower control arm to the stock knuckle. Set the (2) stock bolts aside. Repeat procedure on the
passenger side.
13. Move back to the stock upper control arm castle nut
that connects the upper control arm to the stock knuckle
and remove completely. Set the stock castle nut, stock
knuckle and hub assembly aside. Repeat procedure on the
passenger side.
14. Working on the driver side, carefully tie the stock CV
axle to the stock upper control arm so that once the stock
coil over is removed and the stock lower control arm is
removed the CV axle will not over extend and cause damage. Repeat procedure on the passenger side.
15. Working on the driver side, remove the (4) stock nuts
holding the stock coil over into the stock upper location.
Save the (4) stock nuts. Now remove the stock lower
mounting hardware that connects the stock coil over to the
stock lower control arm. Set the stock lower hardware and
the stock coil over aside. Special note: To help make
remove of the stock coil over easier, loosen but do not
remove the stock front and rear hardware securing the
stock lower control arm to the stock location. Repeat
procedure on the passenger side.
16. Working on the driver side, remove the stock front and
rear hardware that connects the stock lower control arm

shorter of the two stock bolts. The longer stock bolt and
bracket may be discarded.
19. Working on the back side of the stock rear cross member, measure from the center of the of the stock lower control arm mounting location to the the inside of the vehicle 2
1/2” and scribe a mark. Repeat procedure on the passenger side. Using a sawzall, carefully cut the rear cross member out of the stock location. Follow the lines that were
scribed on the driver and passenger side of the stock rear
cross member and also make sure to cut all the way
through the rear cross member. The stock rear cross member may be discarded. Special note: Tuff Country does
