It's a known fact; during acceleration, cornering, and braking your chassis will flex and twist. The more power you add or the stiffer the suspension, the worse it becomes. All this movement uses up valuable horsepower, decreases handling characteristics, and reduces ride quality. So why spend time and money improving your engine and suspension when it's attached to a flaccid frame? Stifflers Suspension F-150 chassis stiffening systems bridge the front and rear sections of the F-150 frame to significantly increase its stiffness and reduce the twisting and bending caused by suspension inputs and drivetrain torque. The systems are designed for ease of installation with minimal drilling--all other mounting locations use existing holes. Stifflers F-150 chassis stiffening systems are complete with integrated brackets for optional driveshaft safety loops (sold separately). So what does this mean for you? * Straighter launches * Less wasted horsepower * More responsive suspension tuning * Improved handling under cornering and braking * Better ride quality * Fewer squeaks and rattles NOTE: Other manufacturers' long bars cannot be used with these systems.
