Common Questions
What does the DSC adjuster actually let me do?
Dual Speed Compression gives you independent control over low-speed and high-speed compression damping. You can dial the shock toward a softer, more comfortable setting for daily driving and towing, or firm it up for high-speed rough terrain — without removing the shock from the truck.
Does this fit a Tremor package truck?
Yes, confirmed compatible.
Does this fit a 2010 F-350?
No. This part number is for the 2017+ redesigned Super Duty chassis. A pre-2017 truck needs a different Fox Performance Elite part number.
Is this the same as the 2.5 HTO?
No. The HTO uses fixed valving with Hydraulic Top Out technology for smoother top-outs. The Performance Elite adds an external DSC adjuster, letting you actively tune compression damping yourself — a genuinely different capability, not just a marketing tier name.
The Obsidian Take
The 883-26-096 is for the 2017-2026 F-250/F-350 Super Duty 4WD owner who wants the ability to actively tune their rear shock damping — not just a fixed valve calibration, but a real external adjuster for dialing in ride quality across daily driving, towing, and rough terrain. This is Fox's top tier for a reason: the DSC adjuster is a genuine functional upgrade over the HTO and standard 2.0 lines, not just a price-tier label.
Confirm your truck is 2017 or newer before ordering — the pre-2017 generation needs an entirely different Fox part number, regardless of which tier you're shopping.
