🧾 Overview
The FOX Performance Series 2.5 HTO Rear Shocks are a premium, bolt-on suspension upgrade engineered for Jeep Wrangler JL owners who demand improved control, comfort, and durability—especially on lifted rigs running larger, heavier tires. Featuring Hydraulic Top Out (HTO) technology, these shocks deliver position-sensitive rebound control that reduces harsh top-outs and improves ride quality both on-road and off-road.
Built around a 2.5-inch aluminum shock body with an Internal Floating Piston (IFP), the FOX 2.5 HTO separates shock oil from high-pressure nitrogen to maintain consistent damping and reduce fade. Vehicle-specific valving and larger pistons increase damping capacity, making these shocks especially effective for JL applications lifted beyond OEM specifications.
✔ Hydraulic Top Out (HTO) for smoother rebound control
✔ Increased damping capacity with 2.5” body
✔ Optimized for lifted JL applications and larger tires
✔ Bolt-on installation with race-proven FOX technology
