FOX 987-02-013 2.5 Performance Series IFP Front Coilover 2015-2026 Ford F-150

Vehicle Fitment

• 2015-2026 Ford F-150 (All Trims, 4WD) - Non-Tremor models: 0-2.5" lift
• 2021-2026 Ford F-150 Tremor (4WD) - 0" lift (leveling application)
• 2021-2026 Ford F-150 PowerBoost Hybrid (4WD) - 1.5" lift

Fitment Notes

• Front position only - sold as a single coilover; order two for a complete front pair
• 4WD models only - not compatible with 2WD/RWD F-150 configurations
• Not compatible with F-150 Raptor - Raptor uses a different front suspension architecture
• Tremor trim is supported at stock height (0" lift) only due to factory Tremor-specific suspension geometry
• PowerBoost Hybrid trim is supported at 1.5" lift only due to added front-end weight from the hybrid drivetrain
• Bolt-on installation using OEM front strut top mount - no modifications required
• Alignment recommended after installation
• Pairs with FOX rear shocks (sold separately) for a complete front-to-rear Performance Series upgrade

Features

• FOX 2.5 Performance Series IFP (Internal Floating Piston) monotube coilover - separates shock oil from high-pressure nitrogen gas to eliminate oil aeration and deliver consistent, fade-resistant damping across all terrain types
• Larger 2.5-inch body over the standard 2.0" Performance Series provides greater internal oil volume and superior heat dissipation for sustained performance under demanding conditions
• Application-specific valving precision-tuned by FOX engineers for the 13th/14th generation F-150's weight distribution and suspension geometry, with dedicated calibrations for standard, Tremor, and PowerBoost trims
• 2.5-inch impact-extruded 6061-T6 aluminum body with Type II clear-anodized finish for excellent corrosion resistance and heat dissipation
• High-flow velocity-sensitive damping piston for precise, progressive response on- and off-road
• 5/8-inch hard chrome-plated heat-treated alloy steel shaft for durability and long service life
• Black-anodized CNC-machined 6061-T6 billet aluminum components throughout
• OEM-style top mount with composite bushing isolates NVH for a refined on-road feel
• Locking spring preload ring allows easy ride height adjustment within the supported lift range
• 100% serviceable and re-valvable for long-term ownership

Product Description

The FOX 987-02-013 is a front coilover engineered specifically for the 2015-2026 Ford F-150 4WD, stepping up from the standard 2.0 Performance Series with a larger 2.5-inch body that delivers more internal oil volume and substantially better heat management during extended off-road use. The IFP monotube design permanently separates oil from nitrogen to prevent aeration, ensuring the shock's damping curve stays consistent whether on a daily commute or a hard trail run. FOX's vehicle-specific valving is calibrated for the aluminum-chassis F-150's unique weight distribution, with dedicated tuning variants for standard trims (0-2.5" lift), the Tremor (level/0" lift), and the heavier PowerBoost Hybrid (1.5" lift).

Installation is a direct bolt-on to the factory front strut mounting points with no modifications required. The OEM-style top mount retains factory NVH isolation, keeping the on-road character intact while substantially improving off-road damping control and overall suspension feel. The 5.21 inches of travel, 22.00-inch extended length, and 16.79-inch collapsed length are sized precisely for the F-150's front suspension envelope, ensuring full travel is available without binding or interference. The shock is fully serviceable and re-valvable, making it a long-term suspension investment for owners who build their trucks progressively over time.
