Headquartered out of Unterumbach, Bavaria, delta4x4 — also known simply as “THE OFFROAD COMPANY” — is a renowned off-road tuning outfit that’s been upgrading and building out off-road and overland projects for more than 40 years. And while the company already offers services for a wide range of vehicles, a recent request from a client on the Arabian Peninsula has led to what’s almost certainly delta4x4’s most noteworthy and ambitious project to date with a hardcore off-roading kit for the Rolls-Royce Cullinan.
The off-road package starts with a lift kit of at least 3.15” and a set of delta4x4’s own 20” Force off-road wheels shod in Mickey Thompson Baja Boss tires — a wheel and tire setup that alone costs over $16,000. Custom flared wheel arches also open up space to accommodate the larger wheelset and all-terrain tires. When combined with its larger wheels, the luxury SUV’s ride height increases by at least 6”, too. Off-road protection comes in the form of a full-length skid plate, a protected exhaust system, and a custom steel front bumper that’s equipped with a pair of three-light PIAA clusters.
The top of the Cullinan is lined with a bespoke, diamond-plate-lined roof rack that houses a pair of jerry cans, a pop-up hard-shelled rooftop tent, a snow shovel held in a custom mount, and a trio of recovery boards. An additional four PIAA spotlights have been mounted to the front of the roof rack, and a snorkel system has also been installed. The same rugged construction used to craft the kit’s custom fender flares has also been used to fortify the SUV’s hood, as well.
The delta4x4 off-road kit for the Rolls-Royce Cullinan will be available in the coming months as a complete package, with pricing set at €150,000 (~ $163,250) — plus the cost of the Cullinan donor’s $330,000 MSRP. Individual elements of the kit can also be purchased a la carte.
