FOX 987-24-050 2.5 Performance Series HTO Rear Shock for 2013-2015 Ram 3500 with 0-3 in. Lift

FOX 2.5 Performance Series HTO shock is a bolt-on shock loaded with position-sensitive technology vehicle-specific valving and larger pistons to improve on and off-road performance. A type II anodized aluminum body efficiently dissipates heat and prevents corrosion. The 2.5-inch shock body features an internal floating piston (IFP) to separate the shock oil from the high-pressure nitrogen optimizing damping. Hydraulic Top Out (HTO) technology offers usable position-sensitive rebound damping control on and off the pavement. HTO reduces harsh top-outs and increases comfort by forcing shock oil through a secondary shim stack to slow down shock shaft speed; HTO is particularly beneficial after installing heavier aggressive tires and applications lifted higher than OEM specification. Bolt-on 2.5 Performance Series HTO shocks to increase damping capacity and ride in comfort with position-sensitive rebound control. Application specific valving to maximize performance. Increase your vehicle's off-road capability by extending drop-out travel in most applications. Experience on-road comfort with performance-minded shock valving for a connected ride with less vehicle sway.

Improve the ride quality, damping control, and off-road capability of your Ram 3500 with the FOX 987-24-050 2.5 Performance Series HTO rear shock. Designed for trucks with a 0-3 inch lift, this bolt-on shock uses vehicle-specific valving to provide a controlled, connected feel on pavement while increasing performance over rough terrain. Its Hydraulic Top Out (HTO) technology delivers position-sensitive rebound control, helping reduce harsh top-outs and improve comfort when the suspension reaches full extension.

The 2.5-inch impact-extruded 6061-T6 aluminum body efficiently dissipates heat and resists corrosion, supporting consistent performance during demanding towing, off-road, and high-load use. A true internal floating piston (IFP) separates the shock oil from the high-pressure nitrogen to optimize damping consistency and help minimize fade. The race-developed main piston and high-flow velocity-sensitive damping design further enhance control, particularly for vehicles equipped with heavier tires or lifted suspension systems.

Built for long-term service, the FOX Performance Series HTO shock features a hard-chrome shaft, Type II clear anodized body plating, and a fully rebuildable and re-tunable construction. The application-specific tune is engineered for the rear suspension of the 2013-2015 Ram 3500, helping deliver improved stability, reduced body motion, and dependable performance in both daily driving and off-road conditions. This shock is sold individually and is intended as a direct bolt-on replacement for compatible applications.
