Keep your Volvo cab riding smooth and stable with the High Soar Air Spring Bag, designed as a heavy duty cab/sleeper air spring for select Volvo trucks. This replacement air bag is engineered to match popular Volvo and aftermarket part numbers, including 1S5-171, Volvo 8074629, Volvo 20462622, Volvo 21165207, helping restore proper ride height, comfort and safety.
Built from imported high-density rubber and multi-ply construction, this air spring is made to exceed typical OEM performance. The durable bellows and reinforced components provide excellent load support, resist cracking and fatigue, and deliver a long service life in demanding commercial use.
By absorbing road shock and vibration, the High Soar cab air spring reduces harsh impacts in the cab, protects driver and passenger from collision forces and contributes to more stable braking and handling. It is an ideal replacement when the original air bag is leaking, sagging or damaged.
- Direct replacement for Volvo truck cab/sleeper suspension – designed to fit applications using 1S5-171, 8074629, 20462622, 21165207.
- Premium quality air ride – high-density rubber bellows and reinforced construction offer better durability and load capacity than many standard air suspensions.
- Enhanced safety & comfort – air spring bags help prevent harsh impact transfer to the cab, improve ride comfort and support more controlled braking.
- Engineered components – includes piston, bellows, girdle hoop and bumper (bump stop) to help protect the cab and suspension during sudden air loss.
- Easy installation – designed as a bolt-on replacement when matched correctly by OE / cross reference number.
- Quality backed – suitable for commercial-duty Volvo applications when installed and maintained properly.
Key component design:
- Piston – lower section of the air spring made from aluminium, steel or composite plastic; provides the lower mounting arrangement with threaded holes or studs.
- Girdle hoop (centre ring) – a ring between convolutions on convoluted style air springs that helps provide stability and shape control.
- Bellows – the heart of the air spring, made from at least four layers: inner layer, two plies of cord-reinforced fabric and an outer protective layer for strength and flexibility.
- Bumper (bump stop) – a solid moulded rubber fail-safe device used in many suspensions to prevent excessive damage in case of sudden air pressure loss.
How to confirm fitment:
- Locate and read the part number on your original cab/sleeper air spring.
- Confirm it matches one of the following: 1S5-171, Volvo 8074629, Volvo 20462622, Volvo 21165207.
- Verify your truck is a Volvo model equipped with this specific cab or sleeper air spring.
- If you are unsure, consult your mechanic or parts manager before ordering.
