Seemingly not content with letting Ford grab all the headlines with its new Ranger Raptor, Toyota has whipped the covers off its updated range of TRD Pro Series models in the United States.

Don't, of course, expect to see these monsters in South Africa...

Set to debut at the 2018 Chicago Auto Show, the Japanese automaker’s TRD Pro off-roading line-up – which was first revealed in 2014 – has been given an update, with the Tundra, 4Runner SUV and Tacoma all now featuring Fox shocks and what Toyota calls “a host of impressive off-road equipment”. No changes, however, appear to have been made under their respective bonnets.

Each of the three models now uses 2,5-inch TRD Pro-exclusive Fox Internal Bypass shocks that employ a piggyback reservoir to house additional oil volume. Tuned specifically for each vehicle, the aluminium-bodied front dampers are paired with special TRD springs.

The Tundra is equipped with rear leaf springs, the Tacoma uses progressive-rate off-road leaf springs while the 4Runner utilises TRD Off-Road grade rear coil springs.

The Toyota Tacoma TRD Pro boasts a front skid plate with TRD lettering and a cat-back TRD exhaust complete with black chrome tip. Its 16-inch alloys are wrapped in P265/70 Goodyear Wrangler Kevlar All-Terrain rubber, while the standard 3,5-litre V6 draws its air from a snorkel intake.

The Tundra TRD Pro, meanwhile, gains the LED treatment for the headlamps and foglamps, while new 18-inch BBS forged-alloy, five-spoke satin black wheels are shod in Michelin P275/65 all-terrain tyres.

And the 4Runner TRD Pro? Well, the hefty SUV features a new roof rack as well as 17-inch matte-black TRD alloys wrapped in Nitto Terra Grappler P265/70 all-terrain tyres.

All models feature a number of fresh interior appointments, with TRD badges left, right and centre...
