The ’11 Ford Super Duty is an impressive truck with a quiet and strong diesel engine, supple suspension, and workhorse genetics, but we all know stock trucks don’t stay that way for long when the keys fall into the hands of four-wheelers. We just got back from the Rancho Suspension prototype shop, where we upped an F-250 with a 4-inch lift kit and were pleased to find the installation was quick and easy and the ride quality is just like a stock truck.
Rancho, a division of Tenneco, has an advantage when developing its Super Duty suspension in that Tenneco is an original equipment supplier for Super Duty suspension components. In fact, the FX-4 Super Duty comes equipped with Rancho shocks and Tenneco radius arm bushings from the dealer floor, so when you’re looking for an increase in Blue Oval altitude, Rancho is an obvious choice.
The suspension install should take about a day depending on the condition of the truck and tools available. The lift is designed to clear a 37-inch tire, but depending on wheel backspacing and tire/wheel width, we feel you may be able to go even higher due to the Ford’s massive wheelwell openings.
