1988 Ford F-150 XL Regular Cab 4x2 Styleside box — 4.9-liter EFI inline-six

Ford's 1988 truck brochure identifies the Custom, XL, and XLT Lariat F-Series trims plus Regular Cab, SuperCab, 4x2, and 4x4 bodies. Ford's towing guide independently lists the 4.9-liter EFI inline-six with manual transmission for F-150 Regular Cab and SuperCab 4x2 and 4x4 trucks. The available factory tables do not cross-tab both pickup-box lengths or each individual gearbox to every engine, so this page preserves only the verified body and transmission-category boundary.
