Increase the off-road capabilities while improving the comfort and handling of your F-150
The 2.5 IFP shocks provide the optimal combination of:
Firm and stable handling for driving on desert and fire roads (sports car feeling);
Plush compliance while off-road driving over washboard;
Strong ramping effect for extra bottom-out protection over large dips and washes;
Maximum articulation and traction for rock climbing.
BENEFITS
High-performance off-road capabilities
Improved handling and comfort for casual driving
Better traction
Provides leveling capabilities for better weight distribution
Increased protection against bottoming-out
RIDE ENHANCEMENTS
Spring setup optimized for each setup
Better attenuation of vibration, leading to major noise reduction in the cabin (much less squeak and rattle)
Damping characteristics optimized for each truck and setup, providing a smoother ride
Increased comfort in both on road and off-road conditions, especially over washboard and square-edge impacts
More stable and more predictable handling
Reduced front-end diving when cornering or braking
Reduced rear-end bucking and lifting
Increased damping and spring rate for better handling when towing or loading truck

The 2.5 IFP model is a simple bolt-on upgrade over OEM shocks. They are a gas-pressurized design with internal floating piston to help prevent cavitation and fading.
This configuration is for use with stock geometry and can accommodate 0 in. to 2 in. of lift with either stock or aftermarket upper control arms.
Ride height is preset from our factory at approximately 1.5 in. of lift for a stock truck with stock tires, actual ride height may vary depending on wheels dimensions and upper control arms used.
