4.5-8" Rear Shock Absorbers for 2007-2025 Chevy Silverado/GMC Sierra 1500

Shocks offers 10 Stage variable valving, high-pressure Nitrogen charged that offer a fantastic blend of off-road action and smooth highway ride quality. With a durable 18mm spring loaded piston rod and faster-cooling 54mm shock body, this shock offers up to 36kN Tensile Strength for a long lifespan of impressive vibration dampening. Features natural rubber bushings and an eye catching metallic silver paint.

• 【Fitment】:Fits 2007-2025 Chevy Silverado/GMC Sierra 1500. No cutting or welding required. Installs in factory location. Lifts 4.5-8 inches
• 【10-Stage Adjustable Damping】:Tailor-tuned for Chevy/GMC 1500; switches between off-road stability and highway comfort, solving stock shocks’ “jolts/swaying”
• 【-50°C Extreme Cold Resistance】：Specialized low-temperature damping fluid maintains shock absorption stability even in extreme cold, preventing winter suspension hardening and abnormal noises.
• 【36kN High Tensile Strength】:The piston rod seal withstands 36kN tensile force, reducing suspension damping under heavy loads for enhanced vehicle stability during towing. This effectively improves safety and comfort during heavy-duty driving.Features a rubber protective cover that reduces dust and rain erosion, extending service life.
• 【54mm Large-Diameter Heat Dissipation】：Aluminum alloy cylinder paired with a 54mm large-diameter cooling structure, boasting 30% higher heat dissipation efficiency than stock shocks. Prevents shock absorber overheating and failure during continuous steep climbs or desert crossings, ensuring braking stability. Service life is twice that of the original.
• 【Dual Noise Reduction】:High-pressure nitrogen filling suppresses oil cavitation. Combined with natural rubber buffer bushings replacing the original steel bushings, noise is reduced by 40% when traversing speed bumps at high speeds, completely eliminating abnormal noises.
