SABO 9002 Air Spring — Firestone W21-760-9002 (ASL4002A / ASL4002R)
SABO 9002 Air Spring — Firestone W21-760-9002 (ASL4002A / ASL4002R)
A single sleeve air spring used across a range of 4-corner air suspension systems, most commonly found in the front-of-rear position on 4-bag setups including Gliderite AE installations. Supplied as a complete assembly — top plate, piston and sleeve are permanently joined and not detachable.
The rubber sleeve length is 240mm — this is a key identifying feature of the 9002. If your existing spring has a different sleeve length it is likely a different variant in the same series and may require a different replacement part. If you are unsure, contact our team before ordering.
Available in two variants:
- ASL4002A — SABO equivalent. A direct OE replacement for the Firestone original. UK stock held.
- ASL4002R — Firestone OEM original. For those requiring a genuine branded replacement.
Both variants are direct replacements for the Firestone W21-760-9002 and SABO IC9002 references.
For the rear-of-rear position on the same 4-bag system, see ASL4004A.
