Firestone 267C-1.5 / 255C-1.5 Air Spring — OE Replacement(ASL2025A / ASL2025R)

A Sabo replacement for the Firestone 255C / 267C-1.5 double convoluted air spring, fitted to Ride-Rite air assist suspension systems and a range of semi-air kit applications. The 267C-1.5 marking on the rubber bellow is shared across multiple air spring assemblies — correct identification depends on the full mounting configuration, not the bellow number alone.
 
This is one of several "267C-1.5" variants — verify before ordering
 
The 267C-1.5 / 255C-1.5 bellow appears on at least six distinct air spring assemblies, each with different mounting configurations and end plates. The rubber may look identical, but the metalwork differs. Common variants in our range include:
 
ASL2025A / ASL2025R — Ride-Rite OE replacement (this product) — 1/4 BSP top connector, M10x1.5 mounting both ends, 114mm plates
ASL2023 — alternative mounting configuration
ASL2024, ASL2044, ASL2052 — variants with different plate diameters and connector types
 
Cross-reference databases will often return multiple results when searching the bellow number alone. Please use the dimensional specifications below to confirm fitment before ordering. If you're unsure which variant you need, contact us with photos of your existing spring's mounting configuration.
 
Identifying this specific variant (ASL2025):
This assembly has a 1/4 BSP top air connector, M10x1.5 mounting threads at both top and piston, 114mm top plate diameter and 114mm piston diameter, with 25mm top offset. If your existing spring has different mountings, end plate sizes or air connector type, this is not the correct replacement.
 
Available in two variants:
 
ASL2025A — SABO equivalent. Aftermarket OE-spec replacement. ASL2025R — Firestone OE original. For those requiring genuine branded replacement.
Both are direct replacements for the Firestone 267C-1.5 reference in this specific assembly configuration.
