Abstract: Sway bars are described that include at least an inner sway bar, a first outer sway bar, and a second outer sway bar. The sway bar includes a first coupling portion and a second coupling portion that can engage and disengage under control from a remote location. The sway bar includes a larger diameter, outer sway bar assembly that can be disengaged and a smaller diameter inner sway bar. The sway bar can include a housing to retain fluid.

Abstract: Locking differentials are described that include a first orientation and a second orientation. In the first orientation, the locking differential has a default unlocked position and must be actuated to be locked. In the second orientation, the locking differential has a default locked position and must be actuated to be unlocked. The user selects whether the locking differential is in the first orientation or the second orientation.

Abstract: Strut spacers are described that include at least a male component comprising an externally threaded surface and a female component comprising an internally threaded surface. Rotation of the male component or the female component adjusts the height of the strut spacer prior to installation within the motor vehicle. The strut spacer can optionally include a locking ring to lock the height of the strut spacer before installation.

Abstract: A spring seat to define a spring height for a vehicle suspension system including a base cylinder defining an interior cylindrical surface and an exterior cylindrical surface, an external attachment mechanism coupled to the exterior cylindrical surface of the base cylinder to receive a coil spring on either of two opposing surfaces of the external attachment mechanism, and an internal attachment mechanism coupled to the interior cylindrical surface of the base cylinder, the internal attachment mechanism to engage a shock absorber on either of two opposing surfaces of the internal attachment mechanism, the internal attachment mechanism offset along a longitudinal axis of the base cylinder from the external attachment mechanism to provide two separate height settings for the coil spring relative to the shock absorber in the vehicle suspension system.
