1. ICON RECOMMENDS USING 07-UP GM 1500 TUBULAR UCA KIT (PART #78600 OR #78601). IF NOT USING UCA KIT (PART #78600 OR #78601), TRIMMING THE FACTORY UCA DROOP STOP IS REQUIRED.

3. DO NOT PRELOAD THE COIL BEYOND .875” OF EXPOSED THREADS BETWEEN THE BOTTOM OF THE TOP CAP AND THE TOP OF THE COIL ADJUSTER NUT.
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.
INSTALLATION
1. Using a properly rated hydraulic jack, lift the vehicle and support the frame rails with jack stands. Ensure jack stands are secure and set properly before lowering the hydraulic jack. BE SURE TO NEVER WORK UNDER AN UNSUPPORTED VEHICLE. Remove the wheels.
2. Remove the 3 nuts holding the factory coilover to the coil bucket using an 18mm socket/wrench. (FIGURE 1)
3. Remove the 2 bolts from the lower bar pin using a 15mm socket/wrench. (FIGURE 2)
4. Using some downward force on the spindle, remove the coilover through the opened inner section of the lower A-arm.
NOTE: If using the ICON Tubular UCA Kit (78600/78601), disregard step 5.
5. Using a reciprocating saw/angle grinder, cut the droop stop off of the factory UCA mount as shown. (FIGURE 3 AND 4)
5. Install the ICON coilover while applying downward force to the spindle.
6. The hex side of the bar pin goes toward the rear of the truck.
7. Using the supplied 3/8” hardware and a 9/16” socket/wrench, connect the upper mount to the coil bucket. The reservoir mounting plate bolts to the top of the coil bucket using the outer bolt. [Torque to 30 ft-lbs] (FIGURE 5)
NOTE: Fasten the reservoir to the reservoir mount using the supplied hose clamps and a 5/16” nut driver. Orient hose so it does not contact the coil bucket.C
8. Install the factory lower bolts connecting the lower bar pin to the lower A-arm using a 15mm socket/wrench. [Torque to factory spec] (FIGURE 6)
9. Install the wheels and set the truck on the ground. [Torque to factory spec]
