ICON Vehicle Dynamics V.S. Series 2.5” coilover shocks are an incredible upgrade for the rear end of 2021-2023 Chevrolet Tahoe & Suburban/2021-2023 GMC Yukon & Yukon XL SUVs. Their longer length offers an increase in total rear wheel travel compared to stock, improving suspension performance and ride quality. ICON’s Vehicle-specific valving provides a sport tuned feel on and off-road while 3-4” of rear lift height adjustability on Tahoe and Yukon or 2.5-3.5" of rear lift on Suburban or Yukon XL, allows the use of larger, more aggressive wheel and tire combinations. The larger 2.5” diameter shock body and increased piston area over stock components provides improved damping ability and outstanding ride characteristics across varying types of terrain. Remote reservoirs greatly increase shock oil volume and heat dissipation surface area to resist overheating and cavitation under hard use, which can lead to damper fade. When paired with ICON front 2.5 Series coilover shocks vehicle control will be balanced front to rear, resulting in the best overall driving experience for your GM SUV.
