Engineering Breakdown

Why These Parts Fit the 2026 Ford F-150 Lariat 4x4 Crew Cab

The F-150 IFS suspension utilizes an approximate 1:1.64 motion ratio between strut displacement and vertical wheel hub travel. Installing a 1.25-inch thick billet strut spacer yields roughly 2.05 inches of effective front ride height elevation. Offset changes below +18mm shift the scrub radius outward, increasing inner wheel well liner contact under reverse steering lock.

Side steps attach directly to factory rocker panel weld-nuts or frame outriggers. Modern trucks feature pre-threaded factory mounting locations; always leave bracket bolts hand-tight until the board is positioned squarely to ensure perfect door seam alignment.
