FOX 2.5 Performance Series IFP HTO Shock (REAR)
2014–2025 Ram 3500 6.7L Diesel / 6.4L 392 / 2014–2018 Ram 3500 5.7L Hemi
Part #: 987-24-050
Overview
The FOX 2.5 Performance Series Internal Floating Piston (IFP) Hydraulic Top Out (HTO) shock is engineered to deliver superior rear suspension performance for Ram 3500 trucks from 2014 through 2025. Designed specifically for heavy-duty diesel and gas-powered engines including the 6.7L Cummins Diesel, 6.4L 392 HEMI, and 5.7L HEMI models, this bolt-on shock absorber enhances both on-road comfort and off-road capability. Ideal for drivers who demand improved ride quality, better control, and increased durability, the FOX 2.5 Performance Series shock is a reliable upgrade for lifted trucks or those equipped with aggressive tires.
By integrating position-sensitive valving and larger pistons, this shock optimizes damping characteristics to adapt to varying terrain and driving conditions. Whether navigating rough trails or cruising highways, the FOX 2.5 Performance Series IFP HTO shock provides a balanced, controlled ride that reduces harsh impacts and improves vehicle stability.
Key Features
Built with advanced technology and precision engineering, the FOX 2.5 Performance Series shock offers numerous benefits for Ram 3500 owners seeking enhanced suspension performance:
- Internal Floating Piston (IFP): Separates shock oil from high-pressure nitrogen to optimize damping consistency and reduce cavitation.
- Hydraulic Top Out (HTO) Technology: Provides position-sensitive rebound damping to minimize harsh top-outs and increase ride comfort, especially beneficial for lifted trucks and those with heavier tires.
- Vehicle-Specific Valving: Tailored valving ensures optimal shock response for the Ram 3500’s weight and suspension geometry.
- 2.5-Inch Shock Body: Larger diameter piston improves damping capacity and heat dissipation.
- Type II Anodized Aluminum Body: Lightweight yet durable construction resists corrosion and efficiently dissipates heat for consistent performance.
- Bolt-On Installation: Designed for direct replacement with no modifications required.
- Enhanced Off-Road and On-Road Performance: Balances comfort and control across diverse driving environments.
Construction & Design
The FOX 2.5 Performance Series shock features a robust Type II anodized aluminum body that offers superior corrosion resistance and excellent heat dissipation, critical for maintaining shock performance under demanding conditions. The internal floating piston design separates the shock oil from the high-pressure nitrogen gas, preventing aeration and ensuring smooth, consistent damping throughout the shock’s travel.
Hydraulic Top Out technology integrates a secondary shim stack that forces shock oil through a controlled passage during rebound, reducing the shock shaft speed at full extension. This innovation significantly reduces the harshness of top-out impacts, enhancing ride comfort without sacrificing control. The larger 2.5-inch piston diameter increases the shock’s ability to manage energy, making it well-suited for trucks with lifted suspensions or heavier aftermarket tires.
Installation & Fitment
The FOX 2.5 Performance Series IFP HTO shock is designed as a direct bolt-on replacement for the rear suspension of Ram 3500 models from 2014 to 2025 equipped with 6.7L Diesel, 6.4L 392, and 5.7L HEMI engines. Installation requires no special modifications or custom fabrication, allowing for a straightforward upgrade process. This makes it an ideal choice for enthusiasts looking to improve their truck’s suspension performance quickly and reliably.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
