Cognito 5" Premier Lift Kit with Fox 2.5 Factory Race Series Reservoir Shocks | 2023-2025 Ford F-250/F-350 Super Duty

The Obsidian Vision

Five inches of front lift and three inches of rear lift on a 2023–2025 Ford F-250 or F-350 Super Duty is the build that levels the truck's stance, clears 37x12.5-inch tires on a 10-inch wide wheel, and delivers the Fox Factory Race Series 2.5 Reservoir damping that separates a properly engineered Super Duty lift system from a parts-list assembly. The Cognito 5-Inch Premier Lift Kit is engineered specifically for the 2023–2025 Super Duty platform to correct steering and suspension geometry at the elevated ride height while maintaining adequate droop travel for superior ride quality — every component engineered, manufactured, and assembled in the USA. Before ordering, two requirements must be confirmed: this kit is designed for non-Tremor models, and trucks equipped with the Onboard Scales or Smart Hitch system will experience interference with those systems after installation due to the ride height and spring rate changes this kit introduces.

Engineering Breakdown

• Lifts the front of the 2023–2025 F-250/F-350 Super Duty 5 inches on non-Tremor models by correcting steering and suspension geometry at the elevated ride height — maintaining adequate droop travel for superior ride quality and the corrected front suspension geometry required to run 37-inch tires without accelerating front-end component wear.
• Delivers race-proven damping through the Fox Factory Race Series 2.5 Reservoir shocks, which take their design from Fox's off-road race shock program and have been perfected in the brutal conditions of competitive off-road racing — providing improved damping in any terrain, from highway towing to technical off-road, with the precise control and enhanced ride quality that reservoir shocks deliver over non-reservoir designs at 5 inches of front lift.
• Levels the truck's stance front to rear with 3 inches of rear lift on non-Tremor models, achieving a level front-to-rear appearance and the rear ride height required to maintain proper driveline geometry and tire clearance at the 5-inch front lift increment.

The Fox Factory Race Series 2.5 Reservoir shocks are the top-tier Fox reservoir shock for this application — the 2.5-inch body diameter provides increased oil volume relative to standard 2.0-inch shocks, and the external reservoir maintains a constant oil supply to the piston, preventing cavitation and aeration that cause fade during sustained off-road or high-speed use. Fox athletes push the boundaries in competition to develop race-proven performance that translates directly to the street and trail — Factory Series shocks provide improved damping in any terrain. The Cognito front lift components are engineered to correct the steering and suspension geometry changes introduced by 5 inches of front lift on the 2023–2025 Super Duty platform, ensuring the front suspension operates within its designed geometry range at the elevated ride height. All Cognito components are engineered, manufactured, and assembled in the USA. At 330 lbs, this kit ships via LTL freight carrier with residential delivery included.

❌ REQUIREMENTS & CRITICAL NOTICES:
⚠️ NON-TREMOR MODELS ONLY: The stated 5-inch front and 3-inch rear lift heights apply to non-Tremor model year trucks. Tremor models have a different factory suspension configuration — verify your specific trim before ordering to confirm lift height expectations.
⚠️ ONBOARD SCALES / SMART HITCH INCOMPATIBILITY: This kit is not compatible with trucks equipped with the Ford Onboard Scales or Smart Hitch system. Modifying the ride height or spring rate will interfere with these systems' performance and accuracy. If your truck is equipped with Onboard Scales or Smart Hitch, these systems will not function correctly after installation.
Requires front alignment immediately post-installation — at 5 inches of front lift, caster and camber correction is critical before any driving.
Requires ADAS recalibration if equipped with adaptive cruise control, forward collision warning, lane-keep assist, or BlueCruise.
Requires rear driveline angle verification post-installation to confirm u-joint operating angles are within Ford's specification before towing at rated capacity.

Installation & Technical Notes

Estimated Install Time: 9-Hour DIY Install — with a 2-post lift, comprehensive hand tools, torque wrench, and an alignment appointment scheduled immediately after installation.
Tremor Verification: Confirm your truck is a non-Tremor model before installation. Tremor models have factory-lifted suspension geometry that changes the lift height outcome of this kit.
Onboard Scales / Smart Hitch: If your truck is equipped with Onboard Scales or Smart Hitch, be aware these systems will not perform accurately after installation due to the ride height and spring rate changes introduced by this kit.
Alignment Required: Yes — professional front alignment is mandatory immediately after installation. At 5 inches of front lift, caster and camber deviation from Ford's factory specification must be corrected before any driving.
ADAS Recalibration: Models equipped with adaptive cruise, forward collision warning, lane-keep assist, or BlueCruise require front camera and radar recalibration after installation.
Torque Specifications: Refer to Cognito's included instruction sheet for all component torque values — torque all fasteners with the suspension at ride height under load.
Shipping Notice: At 330 lbs, this kit ships via LTL freight carrier. Residential delivery is included. A delivery appointment will be scheduled by the carrier.
