It acts as a pneumatic cushion between the cab and frame, isolating the cab from road vibration and reducing driver fatigue. Over time, the rubber sleeve can crack or leak, causing the cab to bottom out; replacing it restores the smooth ride and protects interior electronics. This is a genuine PACCAR part, also cross-referenced for some Mack and International models. [finditparts.com](https://www.finditparts.com/products/11717882/kenworth-t81-1001)
