Series 2.5” coilover shocks are an incredible upgrade for the rear end of  2021-2026 Chevrolet Tahoe \u0026amp; Suburban\/2021-2026 GMC Yukon \u0026amp; 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. ICON's exclusive Compression Damping Control Valves are included for precisely dialing in your suspension performance. CDCV controls fluid flow under compression, allowing you to achieve the perfect tune whether driving on the street, slow-crawling through the rocks or mobbing across the desert at full throttle. 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.\u003c\/p\u003e\n\u003cp\u003eAPPLICATION NOTE #330: Will not fit SUV submodels equipped with Magnetic Ride Control and\/or Adaptive Air Ride suspension.\u003c\/p\u003e\n\u003cp\u003eRecommended Aftermarket Tires: 33\"x12.50\" (Larger tires may fit but fender trimming and modifications may be required)\u003c\/p\u003e\n\u003cp\u003eAPPLICATION NOTE #357: Most Suburban\/Yukon XL submodels will have rear lift height range of 2.5-3.5\" over stock\u003c\/p\u003e\n\u003cp\u003eAPPLICATION NOTE #55: Shocks are fully serviceable.
