FOX's 2.0 Performance Series is the line behind this rear shock, which the manufacturer lists under Chevrolet and GMC 2.0 Performance Series applications. Its body is an anodized aluminum shock body that dissipates heat faster than a conventional steel body shock, and the remote reservoir sits outside the body to add oil and nitrogen volume. For a lifted HD truck that sees heavy loads and hard trail use, that extra volume is a real durability advantage over a stock damper, which lacks the capacity and heat management for sustained work.
Owners on user forums who paired FOX 2.0 reservoir shocks with a lift report a clear gain in ride control compared with factory dampers, though the results depend on spring setup. Because this is a 4-6 inch rear lift application, a buyer searching for a FOX 980-24-956 rear remote reservoir shock for a lifted Silverado 2500HD or Sierra 3500HD should treat fitment as the first check. Confirm the exact year, drive, and lift height before ordering, since listings vary. Reservoir routing is the main DIY challenge, so plan for clearance at the spring bucket and steering before the truck is on the ground.
Yes. The manufacturer lists an aluminum reservoir clamp as an included feature.
The manufacturer's site provides a vehicle fitment lookup. Fitment years for this part are stated inconsistently across retail sources, so check your exact year, drive type, and lift height against the manufacturer's lookup before ordering.
Owners on user forums report that the manufacturer publishes a rebuild guide for the 2.0 remote reservoir design. One owner reported that refilling the nitrogen charge required a specialty tool beyond a standard nitrogen kit, so confirm service requirements with the manufacturer first.
This is a bolt-on rear replacement, but the remote reservoir makes it more involved than a standard shock swap. Owners on user forums report that the reservoir can strike the spring bucket and limit steering lock, and some have used third-party reservoir brackets that sandwich between the coil insulator and the bucket to solve it. Owners on a 6-inch lift also noted that the rear shocks needed to be compressed to fit. Plan on a standard socket set, a helper to hold the shock while the reservoir is routed, and a check of tire turning clearance before the truck is lowered.
