ICON V.S. 2.5 Series Rear Coilover Kit with CDXS for 2021-2026 Ford Bronco

The ICON Vehicle Dynamics V.S. 2.5 Series Rear Coilover Kit is a bolt-on rear suspension upgrade for 2021-2026 Ford Bronco 4-door models, delivering 1.25-3" of rear lift depending on Sasquatch package configuration. The kit ships as a pair of 2.5" remote-reservoir coilovers with CDXS dual-speed compression adjustment and ICON's progressive dual-rate heavy-rate coil springs.

Shipping: ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.

More Travel and Better Damping Than Stock

The 2.5" shock body and increased piston area over OEM components maximize available wheel travel (up to 14") while vehicle-specific valving keeps the ride composed on pavement and controlled on rough terrain. Buyers who have pushed stock Bronco shocks to fade on extended trail runs will notice the difference immediately: the larger shock body and remote reservoir together hold more oil and shed heat faster, resisting the cavitation and damper fade that shortens the useful life of smaller-diameter shocks under hard use.

Independent High- and Low-Speed Compression Tuning

ICON's CDXS (Compression Damping Dual Speed) valving gives separate control over high-speed and low-speed compression force. Each adjustment knob has 10 detented positions, so a driver can dial in handling response independently from overall suspension aggressiveness. A Bronco that sees highway miles one weekend and rocky two-track the next can be tuned for each without changing hardware. The remote reservoir keeps that tuning consistent by maintaining cooler operating temperatures during extended off-road use.

Heavy-Rate Springs for Loaded Broncos

The progressive dual-rate coil springs included in this kit are optimized for Broncos carrying extra gear, a rooftop tent, or other rear weight. The increased spring rate supports that load without sacrificing ride quality when the truck is running light. Note that the heavy-rate springs will produce a slight positive rake (nose-down attitude) on an unloaded Bronco. Buyers who run their Bronco empty most of the time should factor that into their decision.

Features

• 2.5" shock body: larger piston area and oil volume than stock for maximum travel and fade resistance
• CDXS dual-speed compression: 10-position independent adjustment of high- and low-speed compression force
• Remote reservoir: increases oil volume and heat dissipation surface area
• Progressive dual-rate heavy-rate springs: optimized for rear-loaded Broncos
• 6061 aircraft-grade aluminum CNC components: CAD-plated shock bodies, 7/8" diameter shaft, FK rod end bearings
• Fully rebuildable and re-tunable: 100% bolt-on installation, no drilling, cutting, or welding required

Specifications

Who This Is For and Isn't

This kit suits 2021-2026 Ford Bronco 4-door owners, with or without the Sasquatch package, who want increased rear lift, more wheel travel, and tunable compression damping for mixed on- and off-road use, especially those who regularly load the rear of the truck with gear, camping equipment, or a rooftop tent.

This kit does not fit the Ford Bronco Raptor. Two-door Bronco models will sit approximately 0.5" taller than the advertised 4-door lift range, so 2-door owners should account for that difference when selecting this kit. Running 37" tires requires the addition of up travel limiters (ICON part 611074); routing the reservoir hose requires a separate hose routing bracket (611073 for ICON tubular lower links, 611072 for factory lower links). ADAS recalibration is required after installation. Rear reservoir brackets may interfere with some aftermarket step or rock slider mounts, and modifications may be required.

Common Questions

What lift height does this kit provide?

The ICON V.S. 2.5 Series Rear Coilover Kit provides 2-3" of rear lift on 4-door Ford Broncos without the Sasquatch package, and 1.25-2.25" of rear lift on 4-door Broncos equipped with the Sasquatch package. Two-door Bronco models will sit approximately 0.5" taller than these 4-door figures.

Does this kit require any drilling, cutting, or welding to install?

The ICON V.S. 2.5 Series Rear Coilover Kit is 100% bolt-on with no drilling, cutting, or welding required for installation. Running 37" tires requires up travel limiters (ICON part 611074), and a separate hose routing bracket is needed for the reservoir hose: part 611073 for ICON tubular lower links, or part 611072 for factory lower links.

Will ADAS or driver assistance systems need recalibration after installing these coilovers?

Yes. The ICON V.S. 2.5 Series Rear Coilover Kit requires recalibration of Advanced Driver Assistance Systems (ADAS) after installation. This applies to any Ford Bronco equipped with ADAS features and should be performed by a qualified technician following the lift installation.

What does the CDXS adjustment actually control?

CDXS (Compression Damping Dual Speed) valving on these rear coilovers provides independent adjustment of high-speed and low-speed compression force, with 10 detented positions on each knob. Low-speed adjustment affects handling response and body control; high-speed adjustment controls overall suspension aggressiveness over sharp impacts and rough terrain.

Why do these coilovers use heavy-rate springs instead of standard-rate springs?

The progressive dual-rate heavy-rate coil springs in this kit are optimized for Broncos carrying additional rear weight, such as gear, recovery equipment, or a rooftop tent. The increased spring rate supports that weight while maintaining ride quality. On an unloaded Bronco, the heavy-rate springs will produce a slight positive rake (nose-down attitude).
