Abstract: An assembly for actuating a vehicle's brake system from a dual-driver position includes an auxiliary brake pedal coupled to the vehicle remotely from the primary brake pedal. A master cylinder's piston is actuated when the auxiliary brake pedal pivots, and a hydraulic line provides hydraulic fluid to and removes hydraulic fluid from a slave cylinder in response. A lever is provided near the primary brake pedal and has one end coupled to the slave cylinder. The lever pivots in response to provision or removal of hydraulic fluid to or from the slave cylinder. A connector is coupled to the lever's opposite end and moves with the lever. The connector is coupled to a movable member that directly applies force to a rod of a primary brake system actuator and applies force to the movable member at the same location where the primary brake pedal applies force to the movable member.

Abstract: An electronic switching module for connecting first and second throttle assemblies to an electronic control module of a vehicle that controls an engine of the vehicle includes first throttle assembly ports adapted to receive first throttle primary sensor position data and first throttle secondary sensor position data and second throttle assembly ports adapted to receive second throttle primary sensor position data and second throttle secondary sensor position data. A controller is connected to the first and second throttle assembly ports and an electronic control module port and is adapted to receive and compare the first throttle primary sensor position data and the first throttle secondary sensor position data and send an engine idle signal to the electronic control module via the electronic control module port when the comparison does not show a first predetermined relationship.

Abstract: An extension for a vehicle having a frame rail and a cross member with a top flange and a bottom flange, with the cross member connected to the frame rail. The extension includes a top bracket having a vertical portion and a top horizontal member, where the top bracket vertical portion has a leading end portion and a trailing end portion. The trailing end portion is adapted to be attached to the frame rail and the top horizontal member is adapted to engage the cross member top flange. An outer plate is attached to the leading end portion of the vertical portion of the top bracket and has a middle horizontal member. A spacer block is positioned between and attached to the top and middle horizontal members. A bottom bracket has a vertical portion and a bottom horizontal member. The bottom bracket vertical portion is attached to the outer plate and the bottom horizontal member is adapted to be attached to the bottom flange of the cross member.

Abstract: Modified vehicle hoods and methods of modifying truck hoods are provided herein. The modified vehicle hoods are narrowed in width compared to the original truck hood. The modified width of the modified hood may be less than the horizontal width between the forward support posts of a hauler rack, allowing the modified hood to be opened without contacting the support posts. Methods of modifying truck hoods include marking each of the pair of fenders of the vehicle with cut lines, cutting the pair of fenders to remove excess hood material, and then attaching a pair of fender panels to the pair of cut vehicle fenders.

Abstract: A cross member towing hitch includes a cap adapted to engage outer surfaces of a pair of frame rails of a towing vehicle, where the cap includes a hitch plate.

Abstract: A method is provided for modifying a cab assembly of a Class 5 or higher truck. The cab assembly includes a cab. The cab has an original cab height from a cab bottom end to a cab top end thereof. The cab includes a bottom region, a window region located above the bottom region, a roof region located above the window region, and a window defined in the window region. The method includes: cutting the cab through the window region to divide the cab into a top section and a bottom section; and thereafter joining the top section or a replacement top section to the bottom section to form a modified cab, wherein the modified cab has a modified height from the cab bottom end to the cab top end that is less than the original cab height.

Abstract: A truck comprises a motorized body including a chassis and a cab. The cab includes opposed sidewalls, one of which includes an access opening having front and rear edge portions. The door that covers the access opening comprises upper and lower panels. The lower panel is pivotally attached to the front edge portion of the opening to rotate about a first substantially vertical axis of rotation between open and closed positions. The upper panel is hinged to the rear edge portion of the opening to rotate about a second substantially vertical axis of rotation between open and closed positions. The upper and lower panels are sized and configured such that, when each is rotated to its closed position, each spans the opening of the cab, and the upper panel is disposed above the lower panel. In such a configuration, the lower panel can be closed to protect the driver, and the upper panel can be moved to its open position to provide ventilation.
