The Last Line of Suspension
The Rubber Buffer Block is installed at the compression travel limit positions of the suspension system. It is typically placed at the contact points between the subframe or suspension arms and the body. Its main job is to provide progressive cushioning when the suspension compresses to its limit. It absorbs large impact energy and prevents metal-to-metal contact. This block determines the "harshness" of chassis impacts over deep potholes or big bumps, and the "support feel" of body sinking under heavy loads. In simple terms, it keeps the rear from "bottoming out" when fully loaded and stops the chassis from feeling "jarring" over large dips.
