Finding a well-preserved sixth-generation F-Series is getting harder, but this 1978 Ford F-150 Custom Flareside 4×4 proves that some legends only get better with age. Originally leaving the factory with a Styleside bed, this truck underwent a transformation that swapped its rear for a classic Flareside look. This modification, combined with a striking green paint job, gives the pickup a rugged yet refined presence.

Refurbished Body and Outdoor Equipment

The exterior transformation included more than just the bed swap. Builders added a roll bar equipped with LED KC off-road lights to enhance the truck’s utility. A wood bed floor adds a touch of craftsmanship to the rear cargo area. Meanwhile, diamond-plate bumpers and a receiver hitch ensure this vehicle remains functional for modern hauling needs.

Classic Styling with Modern Lighting

While the Dark Jade Metallic paint honors the truck’s roots, the condition reflects a deeper refurbishment. Chrome accents on the front bumper provide a sharp contrast to the deep green bodywork. Dual side mirrors and a steering stabilizer contribute to the overall road presence. Despite some minor rust in the door jamb, the visual appeal remains exceptionally high.

Upgraded Stance and Off-Road Grip

The truck commands attention thanks to a suspension lift and 15-inch polished wheels. These rims are wrapped in 35-inch Kanati Mud Hog tires designed for varied terrain. Power steering and power-assisted front disc brakes make handling this massive machine much more manageable. Manually locking front hubs provide the driver with direct control over the 4×4 system.

Jade Interior and Vintage Details

Inside the cabin, the Jade knit vinyl bench seat maintains the period-correct aesthetic. A woven cover protects the upholstery while matching carpets line the footwells. The dashboard features an 85-mph speedometer and essential gauges for monitoring engine health. A cassette player and a heater ensure that the interior remains a comfortable place for weekend excursions.

Engine Specifications and Drivetrain

Mechanical performance comes from a replacement 400ci V8 engine fitted with a Holley four-barrel carburetor. Long-tube headers flow into a dual exhaust system with Flowmaster mufflers for a deep, resonant sound. This power is managed by a three-speed automatic transmission and a dual-range transfer case. Recent maintenance included new valve covers, gaskets, and a fresh air cleaner.

Chassis Protection and Trail Readiness

The underside of the truck has received corrosion protection on the frame to preserve its structural integrity. The four-into-one headers exit ahead of the rear axle, highlighting the custom nature of the exhaust work. Power-assisted brakes and a heavy-duty cooling system ensure the truck can handle the stress of oversized tires and frequent off-road use.
