The Mack Twin Y Air Suspension is available on the Pinnacle Axle Back and Axle Forward models with S38 and S40 series axles with C125/126, C150/151 and 200 Series carriers. The Mack mRide spring suspension is paired with Mack C150/151 series axle carriers and is available on Granite, Titan, Pinnacle Axle Forward and TerraPro model trucks.

The Mack Twin Y Air Suspension utilizes a Y-shaped high-strength steel design, which according to the manufacturer is up to 403 lbs lighter than other air suspensions and places the load on the suspension entirely on the air ride and not on the pivot bushing. In the Twin Y axle seats are clamped to the axle housing by Huck U-bolts on both sides and never need to be re-torqued.

The Mack mRide spring suspension uses spring leafs over four separate rubber block packs, which the OEM says provides stability and articulation while also allowing clearance for larger tires and brake components required in construction and vocational applications.
