Frequently Asked Questions
What is the ICO67811P?The ICO67811P is the ICON Vehicle Dynamics 2.5 Aluminum Series remote reservoir front shock pair for 2023-2025 Ford F-250 and F-350 Super Duty 4WD trucks. The shocks are length-optimized for use with 4.5-inch ICON lift coil springs and support 4 to 6 inches of total front lift on non-Tremor Super Duty models.
Does the ICO67811P fit 2WD F-250 or F-350 models?No. The ICO67811P is designed exclusively for 4WD Super Duty models. Application Note #1 from ICON confirms it only fits 4WD configurations of the 2023-2025 Ford F-250 and F-350.
What lift height does the ICO67811P require on the Super Duty?The ICO67811P is length-optimized for 4.5-inch lift coil springs. It is compatible with 4 to 6 inches of front lift over stock on non-Tremor Super Duty models, and 3 to 5 inches of lift on trucks equipped with the Ford Tremor package.
Can the ICO67811P be used as a secondary shock?Yes. The ICO67811P can be installed in the OEM front shock location as secondary shocks when using ICON 4 to 6-inch lift coilover conversions. ICON part #611003 is also required for this secondary shock application.
What is the ICON internal Bump Zone feature on the ICO67811P?ICON's internal Bump Zone is created by a 6061 billet aluminum manifold positioned below the top cap of the shock body. When the suspension reaches full compression, this zone generates an additional 20% of damping force to prevent harsh bottoming and control the suspension during high-velocity compression events.
Is the ICO67811P compatible with CDCV compression adjustment?The standard ICO67811P uses fixed vehicle-specific valving. ICON offers CDCV (Compression Damping Control Valve) variants for user-adjustable compression tuning. If adjustable compression is a priority, look for the CDCV version of this shock application.
Are the ICO67811P shocks rebuildable?Yes. Like all ICON shock absorbers, the ICO67811P shocks are 100% rebuildable and 100% re-tunable through ICON's authorized service network. The 5-year ICON Limited Warranty covers defects in materials and workmanship.
What shock oil does the ICO67811P use?The ICO67811P uses premium-grade 5WT shock oil, chosen by ICON for consistent suspension damping performance across a wide operating temperature range, which is particularly important in remote reservoir applications during extended off-road use.
Installation Overview
- Lift the vehicle safely on jack stands and remove the front wheels.
- Confirm the front lift coil springs are already installed at 4.5 inches or within the 4-6 inch compatible range.
- Disconnect the factory front shock upper mount hardware inside the engine bay.
- Remove the lower shock mounting bolt at the axle or control arm. Remove the factory shock.
- Position the ICO67811P in the shock mount location. Thread upper hardware by hand first.
- Seat the lower shock end and torque all fasteners to OEM specification.
- Mount the remote reservoir canister using the included bracket in a protected location away from heat sources.
- Reinstall the wheels. Lower the vehicle and perform a full alignment check.
