Heads up, truck owners!

If your rig’s ride is feeling a little rough or saggy, these air suspension spring bags are exactly what you need to get that smooth float back.

This is a pair—so you’re getting both sides at once, which is always the smart move.

They’re built to OE specs, so they’ll match the original ride quality and durability.

These fit a wide range of applications, including Kenworth models, and they cross-reference with part numbers like 1R11-221, W01-358-9622, K30319, and more.

They’re adjustable, sealed for long life, and made from a solid combo of iron, aluminum alloy, and rubber.
Upper and lower mounts are stud-type, and no extra isolators are needed—just bolt ’em in.

Each bag weighs about 5.78 kg and measures 30x28x26 cm.

Premium Motoring brand, backed by a 1-year warranty.
