Push Your Suspension Beyond The Basics With Fox

If you’re running a lift on your Super Duty and expect it to handle more than just mall parking lots, the FOX 985-24-149 Performance Series 2.0 Rear Reservoir Shock is the upgrade your truck needs. This isn’t your average rear shock, it’s built for hard use, tuned for comfort, and backed by race-proven engineering. Whether you’re hauling a trailer, crawling rocky trails, or hitting washboard roads at speed, this shock helps you stay in control while soaking up the abuse. The external reservoir design increases fluid capacity and keeps temperatures in check, so you won’t deal with fade after a few hard hits. Add in a corrosion-resistant aluminum body, a bold look, and a hassle-free bolt-on fit, and you’ve got a no-compromise solution that actually delivers. It’s the kind of upgrade that gives you confidence on the trail and better comfort on pavement. And when your truck performs better, every drive feels like less of a chore and more like a reward.

Engineered For Control In The Toughest Conditions

Behind the FOX name is a legacy of durability and fine-tuned performance, and the 2.0 Performance Series Rear Reservoir Shock delivers on both. Built around a 2.0 inch metal-impacted aluminum body, this shock dissipates heat faster than standard steel bodies, maintaining consistent damping when things get rough. Its high-flow piston design is race-developed and paired with vehicle-specific valving to dial in response across unpredictable terrain. The 5/8 inch chrome-plated, heat-treated alloy shaft adds strength where it matters most, resisting corrosion and flex under heavy loads. The external reservoir not only looks aggressive, it serves a functional purpose by expanding oil and nitrogen capacity to help prevent cavitation and fade during extended use. FOX also includes CNC-machined billet aluminum mounts and nitrile bushings to keep noise down and articulation up. With an easy bolt-on install and specs built for 1.5 to 3.5 inches of lift, this shock is purpose-built for lifted Super Dutys that see real off-road use.
