TRP Parts has released two new air spring designs to expand its offering in the off-road, vocational market.

The AS70306P and AS9780S are 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.

TRP has also announced an enhanced warranty on its complete line of all-makes air springs. TRP’s Air Spring Performance Guarantee is a promise to buy back any TRP air springs that do not satisfy customer expectations for up to two years after purchase, through any TRP retail location in North America and Latin America.
