Description
FOX 987-24-013 is a 2.5 Performance Series Smooth Body rear shock with an internal floating piston (IFP) and Hydraulic Top Out (HTO) valving, engineered for 2018-2026 Jeep Wrangler JL models running 2 to 3 inches of lift.
IMPORTANT: This listing is for the REAR shock only, valved specifically for a 2″-3″ lift height. Do not confuse this part with FOX 987-24-015, which is the rear shock valved for a 3.5″-4″ lift height on the same platform; installing the wrong lift-height valving will result in incorrect ride characteristics. This shock is sold individually; order two for a complete rear axle installation. A matching front shock for a 2″-3″ lift application is sold separately and is not included with this listing.
FOX 2.5 Performance Series shocks deliver the benefits of a larger 2.5-inch shock body without the added complexity of a piggyback reservoir or external compression adjusters. The 2.5-inch impact-extruded 6061-T6 aluminum shock body is finished with type II clear anodizing to dissipate heat and resist corrosion, while a 5/8″ hard chrome shaft rides through vehicle-specific, position-sensitive valving and a larger piston for improved on-road comfort and off-road control.
Hydraulic Top Out (HTO) technology adds usable, position-sensitive rebound damping control near the top of the shock’s travel. As the shock approaches full extension, HTO routes oil through a secondary shim stack to slow shaft speed, softening harsh top-outs. This is especially beneficial on vehicles running heavier, more aggressive tires or lifted above OEM ride height, where unloaded suspension travel increases.
An internal floating piston (IFP) separates the shock oil from the high-pressure nitrogen charge inside the shock body, keeping damping consistent and preventing oil aeration under hard use. FOX backs this shock with a Limited Lifetime Warranty against defects in materials and workmanship.

This shock fits 2018-2026 Jeep Wrangler JL models running 2″-3″ of lift and is valved specifically for that lift range on the rear axle. This is the rear shock only, valved for 2″-3″ lift; it is not interchangeable with FOX 987-24-015, which is valved for a 3.5″-4″ lift on the same rear position. Confirm your vehicle’s current or planned lift height before ordering to ensure correct damping performance.
