TRP Parts' AS70306P and AS9780S air springs are designed for longer lifespan and lighter weight in vocational applications.

The air springs are manufactured with a proprietary rubber compound and reinforcing material that extends component lifespan by limiting heat-buildup while also reducing weight. TRP’s springs undergo testing and quality control to ensure that the parts are leak-proof.

The AS70360P is a cab suspension spring designed with a proprietary composite base to reduce weight without compromising performance or lifespan.

The AS9780S features a powder-coated steel base that resists corrosion for improved durability and is made to fit the industry’s most popular applications, according to TRP.
