The B&M Truck/SUV MegaShifter automatic shifter gives the driver a choice. Left in "Drive", the vehicle is allowed to shift like a normal automatic, but the driver can also choose to take control and get results similar to a manual. By being able to shift quickly through the gears, the driver can maximize the engine's torque curve, and improve the driving experience. It features full ratchet action performance, and cable operation for easy installation and precise shifting. Configured for light trucks and SUVs, it is sized 14.89" long, 14.85" high, and 6.42" wide, with a taller base and an adjustable floor mount bracket. The base can be trimmed to custom fit any floor, which is useful for applications where the vehicle does not have a factory provided console, or it is no longer desired.
