ICON V.S. 2.5 Series Extended Travel Front Coilover Kit for 2019-2026 Silverado 1500 / Sierra 1500

The ICON Vehicle Dynamics V.S. 2.5 Series Extended Travel Internal Reservoir Coilover Kit is a front-suspension upgrade for 2019–2026 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks, delivering approximately 10 inches of total front wheel travel and 1.5–3.5 inches of lift height adjustability over stock on most gasoline-engine trims. The kit is sold as a pair and requires concurrent installation of ICON front upper control arms.

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, More Capability

The extended-length coilover design, when paired with ICON front upper control arms, produces approximately 10 inches of total front wheel travel, which is more than ICON's standard-travel coilovers for the same application. Greater wheel travel keeps the tire in contact with uneven terrain longer, reducing the jarring deflections that wear out drivers and cargo on rough trails or washboard roads.

2.5-Inch Shock Body and Vehicle-Specific Valving

The larger 2.5-inch diameter shock body and increased piston area improve damping ability compared to stock components. ICON's vehicle-specific valving is calibrated for a sport-tuned feel across on-road and off-road conditions, with superior low-speed control that reduces body roll and increases on-road stability. The internal reservoir extends the oil volume available to the shock, helping maintain consistent damping during sustained off-road use.

Adjustable Lift and Long-Term Serviceability

The 1.5–3.5-inch lift range (on most gasoline-engine trims) accommodates larger wheel and tire combinations without committing to a fixed ride height. The corrosion-resistant CAD-plated shock body and 7/8-inch shaft resist the elements, while the fully serviceable design allows for revalves and rebuilds over the life of the truck. ICON-engineered coil springs are guaranteed against sagging or breakage. The bolt-in design installs into the OEM shock location.

Features

• Approximately 10" total front wheel travel (extended-length design; requires ICON front upper control arms)
• 1.5–3.5" lift height adjustability over stock on most gasoline-engine trims (see application notes for Trail Boss, AT4, and diesel variants)
• 2.5" diameter shock body with internal reservoir for increased piston area and oil volume for improved damping
• Vehicle-specific valving for a sport-tuned feel on- and off-road with reduced body roll
• Fully serviceable design supports revalves and rebuilds; CAD-plated corrosion-resistant body with 7/8" shaft
• Bolt-in installation into OEM shock location; ADAS recalibration required after install

Specifications

Who This Is For and Isn't

This coilover kit suits 2019–2026 Chevrolet Silverado 1500 and GMC Sierra 1500 owners running coil front springs who want extended wheel travel and adjustable lift for overlanding, trail use, or a more capable daily driver. It is compatible with OEM wheels and tires and supports fitment of up to 35-inch tires on the Silverado and 34-inch tires on the Sierra (minor fender trimming may be required).

This kit does not fit Silverado 1500 ZR2 or Sierra 1500 AT4X submodels, any 2019–2026 Silverado 1500 or Sierra 1500 equipped with a 4-cylinder engine, or models with torsion-bar or other non-coil front suspension. Trucks equipped with Adaptive Ride Control require additional parts (ICON part numbers 71021 and 71022) installed at the same time. ICON front upper control arms are required; the extended travel figure does not apply without them. Advanced Driver Assistance Systems (ADAS) must be recalibrated after installation.

Common Questions

Do I need new upper control arms to use this coilover kit?

Yes. The ICON V.S. 2.5 Series Extended Travel coilovers for 2019–2026 Silverado 1500 and Sierra 1500 are designed to be used with aftermarket upper control arms only. The approximately 10-inch total front wheel travel figure is achieved only when paired with ICON front upper control arms.

What lift height will I get with this kit?

Lift height depends on the specific submodel and engine. Most gasoline-engine Silverado 1500 and Sierra 1500 trims gain 1.5–3.5 inches over stock. Trail Boss and AT4 gasoline trims gain 0–1.5 inches. Most diesel trims gain 1–3 inches, and Trail Boss and AT4 diesel trims gain 0–1 inch. All figures are for a stock-equipped vehicle before installation.

Does my truck's Adaptive Ride Control system affect installation?

Silverado 1500 and Sierra 1500 submodels equipped with Adaptive Ride Control require concurrent installation of ICON part numbers 71021 and 71022 alongside this coilover kit. Installing this kit alone on an Adaptive Ride Control-equipped truck is not sufficient; both additional parts must be installed at the same time.

Will I need to recalibrate my truck's driver assistance systems after installing these coilovers?

Yes. Advanced Driver Assistance Systems (ADAS) require recalibration after installation of this coilover kit on 2019–2026 Silverado 1500 and Sierra 1500 trucks. This recalibration should be performed by a qualified technician following installation.

What tire sizes are recommended with this kit?

ICON recommends up to 35x12.50-inch tires for the Silverado 1500 and up to 34x12.00-inch tires for the Sierra 1500 with this coilover kit. Minor fender trimming and modifications may be required to achieve clearance for the recommended tire sizes.
