Regular Cab 4x4 6.5-foot Flareside box, 116.8-inch wheelbase · 4.9-liter inline-six

1986 Ford F-150 Standard Regular Cab 4x4 6.5-foot Flareside box — 4.9-liter inline-six

Ford's 1986 F-Series specification, payload, and dimensions matrices list this F-150 Regular Cab 4x4 6.5-foot Flareside box; the trim chart explicitly excludes XLT Lariat from Flareside. The specification matrix lists the 4.9-liter inline-six plus manual and automatic choices for this cab and drivetrain. Because it does not cross-tab each individual gearbox to every engine, this page preserves the verified transmission category without inventing a specific gearbox pairing.
