Renault Master X70 Rear Air Spring — Dunlop OE Replacement (ASL5012U / ASL5013U)

SKU: ASL5012U — Full Assembly (top plate, piston and rubber bellows)
SKU: ASL5013U — Bellows only (rubber diaphragm replacement)
 
Direct OE replacement rear air spring for Renault Master X70 models fitted with Dunlop full air suspension from the factory.
 
The air spring assembly consists of two serviceable elements. On most vehicles the rubber bellows fails before the metal components — the top plate and piston typically remain serviceable. We therefore offer both options:
 
Full assembly (E114570005) — complete air spring including top plate, piston and rubber bellows. Use when the metal components are damaged or heavily corroded.
Bellows only (E316800035) — rubber diaphragm replacement. Use when the metalwork is in good condition and only the rubber element has failed.
 
Both are direct OE replacements for the Dunlop system as fitted from the factory.
 
A note on air spring identification: Air springs are notoriously difficult to identify correctly. Bellows part numbers alone are often insufficient — the correct replacement depends on the full assembly reference, mounting configuration and how the unit integrates with your specific vehicle's suspension system. If you're unsure which part you need, please contact us before ordering. Getting it wrong wastes time and money; we'd rather confirm the right part upfront.
