Used 2018 Nissan Frontier King Cab Trims Comparison

The base S trim starts with two-wheel drive, an extended cab, a 2.5-liter four-cylinder engine and a five-speed manual transmission. Standard features include 15-inch steel wheels, rear privacy glass, cloth front bucket seats, air conditioning, cruise control, Bluetooth, a rearview camera, a 5-inch central display, steering wheel audio controls, Siri Eyes Free voice command, and a four-speaker sound system with a CD player, USB input and an auxiliary audio jack.

An optional Work Truck package adds a spray-in bedliner, bed rail caps, splash guards and rubber floor mats.

The SV builds on the above features with 16-inch alloy wheels, power accessories (windows, door locks), sliding rear window, and satellite radio. Options include a sunroof on the crew cab and a Value Truck package that adds foglights, rear parking sensors, a rearview camera, a sliding bed extender, a spray-in bedliner, adjustable cargo tie-downs, a Class IV trailer hitch, dual-zone automatic climate control, heated front seats, an auto-dimming rearview mirror, and two extra speakers on extended cabs.

The SV crew cab is also available with the Midnight Edition package, which adds blacked-out 18-inch wheels, side steps, body-colored bumpers, and side mirror housings.

The Desert Runner is a rear-wheel-drive V6 only. Available in either cab configuration, it builds on the base SV equipment list with special styling details, foglights, high-performance shock absorbers and off-road tires. The SV Value package equipment isn't available with this trim.

For serious off-roaders, there is the four-wheel-drive-only Pro-4X. This trim features knobby off-road tires, specially tuned shocks, a locking rear differential, skid plates, automatic headlights, a 5.8-inch NissanConnect touchscreen with navigation, satellite radio and voice controls, a leather-wrapped steering wheel and a first-aid kit. It includes everything in the SV Value Truck package except the trailer hitch and bed extender, which are optional. Crew cabs also get a 10-speaker Rockford Fosgate audio system.

The Pro-4X Premium package, only available on automatic-equipped crew cabs, adds a sunroof, a roof rack with crossbars, heated mirrors, leather upholstery, power-adjustable front seats and a rear-seat center armrest.

The top-level SL is only available as a crew cab with the automatic transmission. It loses the Pro-4X's off-road-oriented equipment but retains most of the items in the Pro-4X Premium package, including a sunroof for long-bed SLs. (The sunroof is a stand-alone option for short-bed SLs.) Additional standard features include 18-inch alloy wheels and side steps that ease access to the cab. The trailer hitch and bed extender remain optional on the Frontier SL.
