Installation Instructions
www.skyjacker.com
REQUIRED TOOL LIST:
* Safety Glasses
* Metric / Standard Wrenches & Sockets
* Allen Wrenches
* Assorted Drill Bits
* Floor Jack
* Jack Stands
* Measuring Tape
* Torque Wrench
* Reciprocating Saw (4WD Models)
* Grinder (4WD Models)
* Welding Machine (4WD Models)
Before beginning the installation, thoroughly & completely read these instructions & the enclosed
driver’s WARNING NOTICE. Affix the WARNING decal in the passenger compartment in clear view
of all occupants. Refer to the Parts List to insure that all parts & hardware are received prior to the
disassembly of the vehicle. If any parts are found to be missing, contact SKYJACKER® Customer
Service at 318-388-0816 to obtain the needed items. If you have any questions or reservations
about installing this lift kit, contact SKYJACKER® Technical Assistance at 318-388-0816.
Make sure you park the vehicle on a level concrete or asphalt surface. Many times a vehicle is not
level (side-to-side) from the factory & is usually not noticed until a lift kit has been installed which
makes the difference more visible. Using a measuring tape, measure the front & rear (both sides)
from the ground up to the center of the fender opening above the axle. Record this information
below for future reference.

Driver Side Rear: Passenger Side Rear:
IMPORTANT NOTES:
• OEM wheels can not be reused in the installation of this suspension lift. 17" diameter or larger
wheels must be used to install this suspension lift.
• This lift is determined from the amount of lift to the front of the vehicle, while only lifting the rear to
a position level with the front.
• If larger tires (10% more than the stock diameter) are installed, speedometer recalibration will be
necessary. Contact your local Toyota dealer or an authorized dealer for details.
• After installation, a qualified alignment facility is required to align the vehicle to the OEM
specifications.

Front Installation:
1. With the vehicle on flat level ground, set the emergency brake
& block the rear tires / wheels. Place a floor jack under the lower
control arm’s front cross member & raise the vehicle. Place jack
stands under the frame rails, behind the front wheel wells & lower the
frame onto the jack stands. Note: If the vehicle is equipped with a skid
plate, remove it at this time. This is in preparation for Step # 8.
2. Remove the front tires / wheels. (See Photo # 1)

20. Install the OEM coil & top assembly to the new Skyjacker strut.
Note: There are four snap ring grooves located on the new Skyjacker
strut body. The ring is installed in the third groove from the bottom of
the strut when shipped. This will yield 6" of lift. The top upper groove
is only to be used when 6" of lift is desired, but aftermarket
accessories have been added that weigh the front end down, ie.
Winch, After Market Bumper, & etc. The lower ring grooves may be
used if you would like to keep the OEM rake. (Front of vehicle lower
than the rear). Once the coil spring seat retaining ring has been
placed, check all suspension components for any contact or
interference. If suspension component contact or interference is
present, lower the coil spring seat by lowering the coil spring
seat retaining ring until no contact or interference is present.
