Product Description

The FOX 883-26-148 Performance Elite Series 2.5 Reservoir rear shocks are a pair of adjustable monotube shock absorbers for 2014-2026 Ram 3500 trucks with 0 to 1.5 inches of lift. Developed from FOX's off-road racing technology, these shocks feature a 2.5-inch impact extruded 6061-T6 hard anodized aluminum body, an external reservoir that separates oil from high-pressure nitrogen gas for fade-free damping, and FOX's DSC (Dual Speed Compression) adjuster system with 10 low-speed and 12 high-speed compression settings for precise tuning to match driving conditions. The race-developed high-flow piston and application-specific valving are tuned specifically for the Ram 3500 platform, while JM92 advanced suspension fluid maintains consistent performance across all temperatures. A 7/8-inch hard chrome plated alloy steel shaft, redundant three-stage sealing system, and PTFE-lined spherical bearings ensure long-term durability. Bolt-on installation uses factory mounting points. Backed by the FOX Limited Lifetime Warranty.
