About the 4 Inch Lift Kit | M1 Struts/M1 | Ford F-150 4WD (2015-2020)
Transform Your F-150 with Rugged Style and Trail-Ready Performance: Give your Ford F-150 a bold new stance and unstoppable capability with Rough Country's 4-Inch Suspension Lift Kit. Designed for aggressive off-road performance and a head-turning look, this all-inclusive kit equips your truck for the path less traveled.
Run Up to 33-Inch Tires with Confidence: Gain the clearance you need to conquer rough terrain. This kit includes durable lifted knuckles and strut spacers, providing room for larger tires while maintaining optimal geometry.
Engineered for a Factory-Like Ride: Precision-designed differential drop brackets, sway-bar brackets, brake line extensions, and a driveshaft spacer work together to maintain proper angles, ensuring a smooth, controlled ride, even with added lift.
Heavy-Duty Crossmembers Built to Last: Front and rear crossmembers are reinforced for maximum strength and feature a modern design tailored to fit newer F-150 models seamlessly.
Level Stance, OEM Compatibility: The system levels the front with the rear for a clean, aggressive profile, and retains the factory track width. Works with 18-inch or larger factory wheels* for hassle-free fitment.
Stronger, Longer-Lasting Rear Blocks: Fabricated rear blocks are engineered to outperform and outlast cast alternatives, delivering enhanced durability in demanding conditions.
Ride Quality You Control: Fully Configurable with Shock/Strut Options: Choose from nitrogen-charged N3 shocks for balanced performance, or upgrade to M1 Monotube shocks for enhanced ride precision and heat dissipation.
Built-In Anti-Axle Wrap Design: Specially designed rear blocks combat axle wrap and eliminate common lift block issues, all while preserving the factory ride feel.
Peace of Mind Included: Rough Country backs this kit with a Limited Lifetime Replacement Guarantee, ensuring your suspension is ready for whatever comes next.
