Product Description

The Fox 987-24-010 2.5 Performance Series Front Shock is a high-performance suspension upgrade engineered for 2020-2025 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD trucks. Featuring advanced Internal Floating Piston (IFP) and Hydraulic Top Out (HTO) technology, this front shock delivers improved damping consistency, smoother rebound control, and enhanced ride comfort over both on-road and off-road terrain. Its position-sensitive valving ensures tailored performance for heavy-duty front suspension applications with 1.5"-2.5" of lift compatibility.

Constructed with a rugged 2.5" impact-extruded aluminum body and a hard-chrome shaft for durability, the 987-24-010 offers reliable performance and long service life. Designed as a direct-fit solution, this shock bolsters control and stability for lifted HD trucks and is sold individually -- replacing both front shocks is recommended for balanced suspension performance and handling.
