TECH NOTES
1. RETURNING TO A STOCK COIL SPRING REQUIRES FABRICATION. IF YOU PLAN TO RETURN
VEHICLE TO STOCK AT A LATER DATE DO NOT DISCARD THE COIL CENTERING CUP THAT IS
REMOVED IN STEP 7.
2. YOUR ICON COILOVER ASSEMBLIES COME SHIPPED AT ICON’S RECOMMENDED RIDE HEIGHT.
REDUCING DROOP TRAVEL WILL REDUCE RIDE QUALITY. DO NOT PRELOAD THE COIL BEYOND
1.5” OF EXPOSED THREADS BETWEEN THE BOTTOM OF THE TOP CAP AND THE TOP OF THE COIL
ADJUSTER NUT. ADJUSTING PRELOAD BEYOND THIS SETTING WILL CAUSE THE COIL TO BIND AND
DAMAGE WILL OCCUR TO COILOVER AND/OR VEHICLE.
3. YOUR ICON COILOVER ASSEMBLIES COME FACTORY CHARGED TO 250 PSI. RELEASING NITROGEN
PRESSURE MAY LEAD TO SHOCK MALFUNCTION AND REDUCED RIDE QUALITY. FAILURE CAUSED BY
LOW NITROGEN PRESSURE IS NOT COVERED UNDER ICON’S WARRANTY POLICY.
