Roush Frontier Pro-4XR quick drive a success

Roush Performance has been closely associated with Ford for years, so it came as a surprise when the company announced it was working with Nissan on a modified version of the Frontier pickup. The resulting Nissan Frontier Pro-4XR is lighter on upgrades than the Mustangs that typically carry the Roush name, but it includes useful, cost-effective changes aimed at off-road enthusiasts. If the truck is well received, Nissan and Roush could expand their partnership further.

From Assembly Line to Roush Facility

The Pro-4XR starts life on the same production line in Canton, Mississippi, as a standard Frontier Pro-4X. The only differences during assembly are unique 17-inch titanium-tinged wheels and Hankook Dynapro AT2 XTreme tires, which are a step up from the Dynapro AT2s fitted to other Pro-4X trucks. After final inspection, the trucks take a short 7-mile detour to a Roush facility where the transformation happens.

There, the stock front suspension is removed and replaced with an Öhlins-based arrangement that includes external reservoir shocks and new front control arms. The new setup lifts the front by 2 inches, while Roush adds a 1-inch lift in the rear using the factory leaf springs. The truck also gets a titanium-colored skidplate, black lug nuts, extensive “R” badging, and headrests embroidered with the Roush logo.

One curious detail: the quarter-panel decal still reads “Pro-4X” instead of “Pro-4XR” like the rear badging. A Roush representative, who previously worked at Nissan on the Frontier, explained that they couldn’t come up with a visually pleasing design for the side decal. After the modifications, the trucks return to the Nissan plant and rejoin the pipeline for delivery to dealers.

For a company that has spent decades tuning Ford products, this shift to a Japanese brand is noteworthy. Roush isn’t just bolting on a supercharger; it’s applying suspension know-how to a midsize pickup that competes in a crowded off-road segment. The approach makes sense: Nissan already offers the Pro-4X trim, so a Roush collaboration adds credibility and a distinct set of upgrades without requiring an entirely new model development cycle. Whether that translates into sales likely depends on how the truck performs in the real world.

Reporters from the outlet were given a short test drive, allowing back-to-back comparisons of a standard Pro-4X and the Pro-4XR on a low-speed course designed to emphasize axle articulation. The writer could kinda-sorta detect a difference. Perhaps the Roush truck kept its front wheels on the ground a little longer, and maybe it landed a little softer when dropping onto an upraised wheel. Or maybe that’s what they imagined because that’s what the Nissan and Roush folks said to expect. A longer drive — both on and off pavement — will be needed to determine what real-world impact the Öhlins shocks, new control arms, and additional lift have on the Frontier.
