Mack Trunnion Seats
Mack trunnion seats are a key part of the Mack rear suspension system. They support the trunnion tube and allow the suspension to pivot and absorb heavy loads while keeping the truck stable and properly aligned.
Why replace your Mack trunnion seats?
Worn trunnion seats can lead to excessive movement, uneven wear, and reduced suspension performance—especially in heavy-duty and vocational applications.
ATS Mack Trunnion Seat Features:
- OEM-engineered fit for Mack suspensions
- One-piece heavy-duty design
- Pressed and reamed bronze bushings for smooth operation
- Grease zerk for easy front-position lubrication
- Built for long service life under heavy loads
ATS offers Mack trunnion seats at about half the cost of Mack dealer pricing, while delivering the same quality and durability you expect from OEM parts.
Additional Options Available:
- Mack internal trunnion hardware kits

Whether you’re performing routine maintenance or a complete suspension rebuild, ATS Mack trunnion seats provide a reliable, cost-effective solution built to handle the toughest road and jobsite conditions.
