ICON Vehicle Specific (V.S.) 2.0 HD Series shock absorbers are the ultimate in cost effective upgrades, specifically tailored by ICON engineers for heavy duty applications. The V.S. 2.0 HD Series shocks are a high-quality upgrade for the everyday street driver and weekend warrior looking for improved on and off-road ride quality and performance. ICON 2.0 HD shocks feature hard anodized 6061 aluminum cylinders with increased wall thickness and taller DU bearings, significantly improving pull apart and side load strength compared to ICON 2.0 Aluminum Series shock absorbers. Press in, bonded rubber upper bushing/bar pin assembly provides factory like fitment and ease of install while also isolating road vibration. Forged aluminum lower mounting clevis maintains factory like fitment and ensures maximum strength. Internal nitrogen reservoirs help provide consistent performance under hard use. Like all ICON shock absorbers, V.S. 2.0 HD Series shocks are 100% rebuildable and 100% revalveable. For those using their vehicle in extreme off road situations, consider the ICON V.S. 2.5 Aluminum Series shocks to handle extra abuse and punishment your suspension will need to endure.This Part Fits: Year Make Model Submodel 2020-2026 Chevrolet Silverado 2500 HD Custom 2015-2026 Chevrolet Silverado 2500 HD High Country 2011-2026 Chevrolet Silverado 2500 HD LT 2011-2026 Chevrolet Silverado 2500 HD LTZ 2011-2026 Chevrolet Silverado 2500 HD WT 2024-2026 Chevrolet Silverado 2500 HD ZR2 2015-2026 Chevrolet Silverado 3500 HD High Country 2011-2026 Chevrolet Silverado 3500 HD LT 2011-2026 Chevrolet Silverado 3500 HD LTZ 2011-2026 Chevrolet Silverado 3500 HD WT 2020-2026 GMC Sierra 2500 HD AT4 2024-2026 GMC Sierra 2500 HD AT4X 2015-2021 GMC Sierra 2500 HD Base 2011-2026 GMC Sierra 2500 HD Denali 2024-2026 GMC Sierra 2500 HD Denali Ultimate 2022-2026 GMC Sierra 2500 HD Pro 2011-2026 GMC Sierra 2500 HD SLE 2011-2026 GMC Sierra 2500 HD SLT 2011-2014 GMC Sierra 2500 HD WT 2020-2026 GMC Sierra 3500 HD AT4 2015-2021 GMC Sierra 3500 HD Base 2011-2026 GMC Sierra 3500 HD Denali 2024-2026 GMC Sierra 3500 HD Denali Ultimate 2022-2026 GMC Sierra 3500 HD Pro 2011-2026 GMC Sierra 3500 HD SLE 2011-2026 GMC Sierra 3500 HD SLT 2011-2014 GMC Sierra 3500 HD WT
