BUMP STOP ASSEMBLY
20220221025 · 2022-07-14 · ·

A bump stop assembly for a UTV with a frame attachment, a shock absorber attachment, two panels, a shock absorber and a bracket. The frame attachment is coupled to the frame of the UTV and the shock absorber attachment is coupled to the shock absorber. The two panels extend between the frame attachment and the shock attachment. The bracket is coupled to the trailing arm of the suspension system of the UTV. The bump plate bracket has a bump plate located to contact the shock absorber when a force applied to the suspension system causes the suspension system to reach a predetermined level of a capacity of the suspension system to absorb. The bump plate transfers a portion of the force applied to the shock absorber. The shock absorber is configured to absorb energy transferred to the bump stop assembly by the force applied to the suspension system.
