ICON Vehicle Dynamics 2014-2020 Ford Expedition 4WD Rear 2.5 VS RR CDCV Coilover Kit

The ICON Vehicle Dynamics V.S. Series 2.5 Rear Remote Reservoir CDCV Coilover Kit fits 2014–2020 Ford Expedition 4WD and delivers 0.75–2.25 inches of rear lift height adjustability alongside vehicle-specific valving tuned for both on-road and off-road use. The kit is sold as a rear-only system; ICON 2.5 Series front shocks are sold separately and recommended for a balanced front-to-rear setup.

2.5-Inch Shock Body for Stronger Damping

The 2.5-inch shock body and its larger piston area give the Expedition's rear suspension more damping capacity than the factory shock can provide. That added capacity translates directly to more composed behavior over washboard roads, rocky two-tracks, and highway expansion joints, because the shock can absorb larger inputs without fading or feeling vague. The CAD-plated shock body and 7/8-inch diameter shaft resist corrosion through the mud, salt, and moisture that come with regular off-road use.

Remote Reservoir Keeps Performance Consistent

The remote reservoir increases fluid volume, which slows heat buildup during extended off-road runs or repeated hard braking on descents. Cooler fluid means the damping curve stays predictable from the first mile of a trail to the last, a practical difference on multi-day overlanding trips where the rear suspension works continuously under load. FK rod end bearings at the mounting points reduce deflection and extend service life compared to standard rubber bushings.

External CDCV Tuning Without Tools

The included ICON CDC Valve provides 10 positions of external compression damping adjustment, moving from soft to firm without removing the shock or reaching for tools. Drivers can soften the rear for a loaded highway run, firm it up for a fast dirt road, and return to a middle setting for mixed terrain, all in seconds. The 6061 aircraft-grade aluminum CNC-machined components keep the adjustment mechanism precise and durable across that full range of use.

Features

• 2.5-inch shock body: larger piston area than stock for improved damping capacity
• Remote reservoir: maintains cooler operating temperatures during extended off-road use
• CDCV external adjustment: 10 compression damping settings, soft to firm
• 6061 aircraft-grade aluminum: CNC-machined components throughout
• FK rod end bearings: extended longevity and minimal deflection at mounting points
• 100% bolt-on: no cutting or welding required for installation

Specifications

Who This Is For and Isn't

This kit suits 2014–2020 Ford Expedition 4WD owners who want 0.75–2.25 inches of rear lift, externally adjustable compression damping, and a shock body sized for sustained off-road use, whether the vehicle sees overlanding trips, towing on rough roads, or daily driving with occasional trail use.

This kit does not fit two-wheel-drive Expedition variants, any model year outside 2014–2020, or any other vehicle. It covers the rear suspension only; front shocks are not included. Tires larger than 33 x 11.50 inches may require fender trimming and additional modifications.

Common Questions

Does this kit include front shocks?

The ICON 91821C Rear 2.5 VS RR CDCV Coilover Kit covers the rear suspension only. ICON recommends pairing it with ICON 2.5 Series front shocks for balanced front-to-rear vehicle control on the 2014–2020 Ford Expedition; those front shocks are sold separately.

Will this kit work with factory wheels and tires?

The ICON rear coilover kit is confirmed compatible with factory Expedition wheels and tires. For aftermarket fitments, ICON recommends 17x8.5, 18x9, or 20x9 ICON Alloys wheels at the specified backspace and offset figures, paired with 33 x 11.50-inch tires; larger tires may require fender trimming.

How is the compression damping adjusted?

The included ICON CDC Valve provides 10 positions of external compression damping adjustment on each rear coilover, with no shock removal or special tools required. Turning the adjuster moves the damping from soft to firm, letting the driver tune the rear suspension for load, terrain, or driving style in seconds.

Does installation require cutting or welding?

No. The ICON 91821C rear coilover kit is a 100% bolt-on installation for 2014–2020 Ford Expedition 4WD. No cutting or welding is required.

What is the purpose of the remote reservoir?

The remote reservoir on the ICON 2.5 VS RR rear coilovers increases fluid volume, which slows heat buildup during extended or repeated off-road use. Keeping the shock fluid cooler maintains consistent damping performance throughout a long trail run rather than allowing fade as the shock heats up.
