TECH NOTES
1. ICON DELTA JOINTS ARE PRE-GREASED FROM THE FACTORY. ICON RECOMMENDS GREASING
THE DELTA JOINT EVERY 3,000 MILES (OR EVERY OIL CHANGE). ADD NEW GREASE UNTIL ALL OF
THE OLD GREASE IS EXPELLED FROM THE BOTTOM OF THE DELTA JOINT ASSEMBLY, WIPE AWAY
EXCESS WITH A RAG OR SHOP TOWEL.
2. ICON RECOMMENDS OPTIONAL BILLET DUST COVER SET (191011) TO PREVENT DEBRIS FROM
PACKING UP AROUND THE ZERK FITTING.
3. ALL ICON UPPER CONTROL ARMS HAVE BEEN ENGINEERED TO ALLOW FOR THE MOST POSSIBLE
CASTER, WHILE STILL ALLOWING THE VEHICLE TO BE PROPERLY ALIGNED. NOTIFY YOUR
PROFESSIONAL ALIGNMENT SHOP OF THIS INFORMATION SO THAT MAXIMUM RIDE QUALITY CAN
BE ACHIEVED.
4. KDSS EQUIPPED VEHICLES WILL REQUIRE THE SYSTEM TO BE DEACTIVATED BEFORE
INSTALLATION, AND REACTIVATED AFTER INSTALLATION IS COMPLETE. REFER TO FACTORY
SERVICE MANUAL FOR MORE INFORMATION.

WARNING!
** READ ALL INSTRUCTIONS THOROUGHLY FROM START TO FINISH
BEFORE BEGINNING INSTALLATION! IF THESE INSTRUCTIONS ARE
NOT PROPERLY FOLLOWED SEVERE FRAME, SUSPENSION AND TIRE
DAMAGE MAY RESULT TO THE VEHICLE!
** ICON VEHICLE DYNAMICS RECOMMENDS THAT YOU EXERCISE
EXTREME CAUTION WHEN WORKING UNDER A VEHICLE THAT IS
SUPPORTED WITH JACK STANDS.
**ICON VEHICLE DYNAMICS RECOMMENDS ALL INSTALLATION TO
BE PERFORMED BY A PROFESSIONAL SHOP/SERVICE TECHNICIAN.
PRODUCT FAILURE CAUSED BY IMPROPER INSTALLATION WILL NOT BE
COVERED UNDER ICON’S WARRANTY POLICY.
INSTALLATION
1. If your vehicle is equipped with Kinetik Dynamic Suspension System (KDSS), deactivate the system before performing ANY work
to the vehicle. Refer to the factory service manual for information on how to deactivate this system. KDSS will need to be reactivated
once the installation is complete.
2. Using a properly rated jack, raise the front of the vehicle and support the frame rails with jack stands. Ensure the jack stands are
secure and set properly before lowering the jack. NEVER WORK UNDER AN UNSUPPORTED VEHICLE. Remove front wheels.
3. Using a jack, slightly lift the lower control arm to prevent the arms from being at full droop.
4. Disconnect the upper ball joint: remove the cotter pin securing the upper ball joint nut. Using a 19mm socket/wrench, loosen the
nut to the end of the shank but do not remove entirely so that the nut protects the threads. Dislodge the taper by either using a ball
joint separator or by striking the spindle on the outside of the taper with a large hammer or hand sledge.
5. Support the spindle so that it does not overextend the CV joints when detached.
6. Using a 10mm socket/wrench, disconnect the ABS line that is routed down the top of the arm. Remove the ball joint nut and
disconnect the upper control arm from the spindle.
7. Using a 19mm socket/wrench, remove the large upper control arm pivot bolt. This hardware will be reused, note direction and
order of components. Remove the nut and washer from the rear side of the long pivot bolt. Carefully feed the bolt forward until it
clears the front of the A-arm. Remove the stock upper control arm.

Before installing your new upper control arms, care must be taken to grease the bushings (liberally) prior to installing assembly.
8.
Failure to grease properly will cause premature bushing wear and increased noise. [FIGURE 1]
FIG.1
9. Install the new ICON tubular upper control arm into the chassis: Note the side and orientation of the arms, the Delta Joint should
be oriented to the back of the vehicle. Make sure that there is a washer placed on each side of the bushings then carefully feed the
pivot bolt through the pivots of the arm and through the pivot tube in the chassis. Use the 150025 washers against bushings. Place
the 605813 washers under the nut and under the head of the bolt. Grease the zerk fittings until you can see that the grease has
worked itself all the way into the bushings and then tighten pivot bolt. [Torque to factory spec]
10. Pivot the Delta Joint stem so that it is inline with the taper bore in the spindle. The new Delta Joint will be very sti the first time
you move it.
11. Rotate the upper control arm downward and install the stem through the spindle taper. Install the supplied flanged nut on the
taper pin. [Torque to 75 ft-lbs]
12. Using a 10mm socket/wrench reattach the ABS line to the threaded hole in the arm with the factory bolt.
13. Install wheels and lower vehicle back to the ground. [Torque to factory spec]
14. Repeat steps on opposite side.
15. Have the vehicle professionally aligned.
VERIFY ALL FASTENERS ARE PROPERLY TORQUED BEFORE DRIVING VEHICLE.
RETORQUE ALL NUTS, BOLTS AND LUGS AFTER 100 MILES AND PERIODICALLY THEREAFTER.
ALIGNMENT NOTE
A MAJOR PERFORMANCE ADVANTAGE OF ALL ICON UPPER CONTROL ARMS IS INCREASED CASTER OVER STOCK. DISCUSS WITH A PROFESSIONAL ALIGNMENT SHOP
THAT YOU WANT THE VEHICLE ALIGNED WITH THE CASTER AT THE MAX OF THE FACTORY RECOMMENDED SETTINGS IF YOU WANT TO TAKE ADVANTAGE OF THE DYNAMIC
EFFECTS OF INCREASED CASTER.
