2018 Ford F-350 Super Duty IV Regular Cab Long box Dimensions, Size & Specs

When the side mirrors are fully extended, the width of the 2018 Ford F-350 Super Duty IV Regular Cab Long box increases to 2690 mm (105.9 inches). This measurement is crucial as it affects the maneuverability of the vehicle in tight spaces such as parking lots, narrow streets, and especially when towing trailers. Drivers need to be aware of this width to avoid collisions with objects or other vehicles, as the extended mirrors significantly increase the vehicle's overall width footprint.

The ground clearance or ride height of the 2018 Ford F-350 Super Duty IV Regular Cab Long box ranges between 196 mm and 216 mm (approximately 7.7 to 8.5 inches). This clearance allows the truck to handle rough and uneven terrain more effectively, improving its off-road capability. A higher ground clearance helps prevent the undercarriage from scraping against rocks or debris and enables the vehicle to drive over obstacles that standard vehicles might not clear.

The 2018 Ford F-350 Super Duty IV Regular Cab Long box, with its length of 5888 mm (231.7 inches) and height ranging from 1976 mm to 2055 mm (77.8 to 80.9 inches), generally challenges the limits of a standard residential garage. Most standard garages have door heights around 2032 mm (80 inches) and depths from 5486 mm to 6096 mm (216 to 240 inches). Since the F-350's length approaches or slightly exceeds typical garage depths and height is near door clearance, fitting the truck requires a garage with larger than average dimensions, particularly to comfortably close the doors without damage.

The 2018 Ford F-350 Super Duty IV Regular Cab Long box is equipped with 17-inch rims paired with 245/75 R17 tires. These tire dimensions offer a balance of strength, durability, and ride comfort appropriate for a heavy-duty pickup. The relatively thick sidewalls of the 245 profile height help absorb road shocks and provide better traction on uneven surfaces. The 17-inch rims ensure a sturdy wheel capable of supporting heavy loads and tough usage, enhancing overall ride quality and load capacity.

The cargo capacity of the 2018 Ford F-350 Super Duty IV Regular Cab Long box is approximately 2222 liters. This considerable volume reflects the practical long box design, allowing the truck to carry large and heavy loads efficiently. This cargo space is ideal for commercial use, construction, farming, or any task requiring hauling of bulky items, offering versatility and functionality in a full-size pickup truck.

Compared to its predecessor, the 2018 Ford F-350 Super Duty IV Regular Cab Long box generally features marginal increases in size. The length of 5888 mm (231.7 inches) is slightly longer, adding to cargo bed capacity while retaining maneuverability. The width of 2032 mm (79.9 inches) is consistent or slightly wider, and the height range of 1976 mm to 2055 mm (77.8 to 80.9 inches) may be higher depending on suspension setup or trim. Additionally, modern enhancements in weight to 2680 to 3207 kg (5909 to 7069 lbs) reflect structural reinforcements and added features for durability and comfort. Overall, the updates focus on improving utility and comfort without drastically altering the traditional full-size heavy-duty feel.

When compared to similar heavy-duty pickup trucks such as the Ram 3500 or Chevrolet Silverado 3500HD, the 2018 Ford F-350 Super Duty IV Regular Cab Long box is competitive in dimensions and weight. Its length of 5888 mm (231.7 inches) places it in the upper range of standard full-size pickups, providing ample cargo bed space without excessive bulk. The width of 2032 mm (79.9 inches) is typical for this truck class, while the curb weight spanning 2680 to 3207 kg (5909 to 7069 lbs) aligns with the robust construction needed for heavy towing and payload capacity. The Ford offers strong payload and towing capabilities, combined with modern features and a solid chassis, making it a favored choice among work-focused consumers.

Due to its large dimensions—length of 5888 mm (231.7 inches) and width including mirrors at 2690 mm (105.9 inches)—the 2018 Ford F-350 Super Duty IV Regular Cab Long box poses challenges in daily usability, particularly in urban settings. Maneuvering and parking require caution as the vehicle occupies more space than typical passenger cars. The extended width with mirrors can limit accessibility in tight parking areas, while its height impacts garage clearance. Drivers benefit from enhanced visibility aids and parking sensors to navigate confined spaces. While excellent for hauling and heavy-duty tasks, the truck is best suited for open spaces or workplaces with ample parking.

The 2018 Ford F-350 Super Duty IV Regular Cab Long box distinguishes itself with a Regular Cab configuration and a long cargo box, focusing on maximizing bed length and payload utility. Unlike Crew Cab or SuperCab versions, the Regular Cab offers seating for two or three passengers, making it ideal for heavy-duty work applications where passenger capacity is secondary to cargo volume. This generation incorporates modern styling cues like a muscular front grille, advanced towing technology, and reinforced chassis components for superior durability. Its long box is preferred for users who regularly transport long materials or equipment, balancing functional design with the truck’s overall powerful performance.
