Description

The technology disclosed herein relates to off-road vehicles. U.S. Patent Application Publication No. 2019/0299736 discloses a vehicle including arms, stabilizer bars, and shock absorbers. The arms are rotatably connected to the body frame and are positioned on each side. The stabilizer bars are supported by the body frame and attached to the left and right arms. The shock absorbers connect the body frame to the arms. The off-road vehicle disclosed herein comprises a body frame, arms rotatably connected to the body frame and positioned on both the left and right sides, a stabilizer bar supported by the body frame and spanning above the left and right arms, and link rods connecting each end of the stabilizer bar to each of the left and right arms.
