Rough Country's 4-inch suspension lift kit gives your 2015-2020 4WD F-150 the height, geometry, and hardware to run larger tires and tackle serious terrain without giving up day-to-day drivability. The kit ships with lifted knuckles, strut spacers, differential drop brackets, sway-bar brackets, brake line extensions, a driveshaft spacer, front and rear crossmembers, and fabricated rear lift blocks, covering every angle of the lift in a single purchase.
Clearance for up to 33-inch tires. Lifted knuckles and strut spacers raise the front end while preserving optimal suspension geometry, giving you enough room to run aggressive off-road rubber. Models retaining factory wheels should stay at no wider than 11.5 inches to avoid fitment issues.
Geometry hardware keeps everything in line. Differential drop brackets, sway-bar relocation brackets, brake line extensions, and a driveshaft spacer work together to correct angles that a raw lift would otherwise throw off, so steering, braking, and drivetrain behavior stay predictable on and off the trail.
Fabricated rear blocks over cast. The welded steel rear lift blocks outperform cast alternatives in both strength and longevity. Their built-in anti-axle-wrap design addresses the wheel hop and drivetrain shudder common with conventional lift blocks, preserving a controlled rear-end feel even under hard acceleration.
Configurable shock and strut options. The kit is available with nitrogen-charged N3 shocks for a balanced, capable everyday ride, or upgradeable to M1 monotube shocks and struts for sharper damping control and better heat dissipation on longer runs.
