Fitment, Shipping & Product Support
The Fox 2.0 Performance Series Front Shock (SKU 980-24-663) is engineered for the 1999–2010 GM HD platform and several closely related GM full-size vehicles, running stock height or up to 1" of front lift. 5.1" smooth-body aluminum construction improves heat dissipation over steel-bodied OEM shocks. The IFP (Internal Floating Piston) design separates oil and nitrogen gas to maintain consistent damping performance through heat cycles during towing, hauling, and rough-road use. Sold as a single front shock.
This shock is valved for 0–1" of front lift, not 0–2". For 2011 and newer Silverado/Sierra 2500HD/3500HD, a different Fox part number is required (985-24-189, valved for 1.5"–3.5" of lift).

Common Questions
Does this fit my 2012 Sierra 2500HD?
No. The 2011+ Silverado/Sierra 2500HD/3500HD uses different front suspension geometry. Order Fox 985-24-189 instead, which is valved for 1.5"–3.5" of lift.
Does this fit a Suburban or Yukon XL?
Yes — confirmed for the 2500 (8-lug) Suburban and Yukon XL, 2000–2013.
Does this fit my Hummer H2?
Yes, 2003–2009.
Do I need one or two?
This listing is for a single shock. Order quantity 2 for a complete front pair, and replace both sides together for handling balance.
The Obsidian Take
The 980-24-663 is for the 1999–2010 GM HD truck owner — or Suburban/Yukon XL 2500, Avalanche 2500, or Hummer H2 owner — running stock height or up to 1" of front lift who wants Fox's IFP damping and aluminum-body heat dissipation over the factory steel shock.
The check that matters most: confirm your truck is pre-2011. The redesigned 2011+ Silverado/Sierra 2500HD/3500HD front suspension uses a completely different Fox part number with a taller valved lift range.
