The FOX 2.0 Performance Series 985-24-192 is a rear shock for lifted Chevy HD trucks in the 1.5 to 3.5 inch lift range. It has an aluminum body, an 11.1 inch travel length, and a remote reservoir that moves heat away from the damper more readily than a steel body. A race-developed high-flow piston paired with application-specific valving keeps damping consistent under load, while towing, or on rough backroads. Owners who run heavy loads or spend time on washboard dirt get a clear benefit over budget lift shocks, since the anodized aluminum body resists corrosion and the reservoir helps resist fade during repeated hard use.
Verify fitment before you order. The product name targets 99-and-newer Chevy HD applications, but the vehicle lists attached to this part number do not agree, and some groupings name 2011 to 2019 Silverado 2500 HD 4WD and RWD trucks. Confirm year, cab, drivetrain, and lift height against the manufacturer's fitment data. Each shock bolts eyelet to eyelet, so the job is a straightforward rear swap. The remote reservoir is the part that needs planning, because it needs clearance and a secure mounting spot, and an aluminum reservoir clamp is included. Searches for 2.0 Performance Series rear shock, Chevy HD lifted rear shock upgrade, and 1.5-3.5 inch lift Silverado 2500HD shock replacement lead to this exact part number.
It is sold individually, so you need two to replace both rear shocks.
An aluminum reservoir clamp is included with the shock. Confirm any additional brackets your lift setup needs before installation, since owners on user forums report that some remote-reservoir installs required aftermarket mounting brackets.
Check your model year, cab, drivetrain, and lift height against the manufacturer's application data, because the vehicle lists tied to this part number vary.
This is a moderate-difficulty bolt-on that suits a home garage with a floor jack, jack stands, a socket and wrench set, and a torque wrench. Support the axle or frame securely, remove the old shock's eyelet hardware, and mount the new unit with the reservoir pointed where it has clearance from the frame, brake lines, and exhaust. Route the reservoir hose so it cannot rub or pinch. Owners on user forums commonly report that reservoir fitment and the shock's extended length need a careful check on lifted trucks, so measure before you torque everything down. Tighten all fasteners to the manufacturer's specification.
