Fox 2.5 Performance Series Rear Shock for 2020-2025 Chevrolet Silverado 2500 HD & 3500 HD, GMC Sierra 2500 HD & 3500 HD - 6.5" Lift
Improve the rear suspension on your lifted heavy-duty GM truck with the Fox 987-24-025 2.5 Performance Series HTO Shock. Engineered for 2020-2025 Chevrolet Silverado 2500 HD and 3500 HD models, as well as GMC Sierra 2500 HD and 3500 HD, this bolt-on shock integrates position-sensitive valving and a larger piston design to deliver consistent damping and responsive handling across varied terrains. Drivers notice immediate improvements in ride stability and reduced body roll during highway cruising or off-road trails, particularly when paired with aggressive tires or higher lifts that challenge stock components. Among available rear shocks for these trucks, the 987-24-025 provides adaptable rebound control through its Hydraulic Top Out (HTO) system, which slows shaft speed during compression to minimize jarring impacts making it the direct match for trucks pushed beyond factory limits.
