Description

Overview

Air Spring Assembly BPW D30 Trailer performance matters because it stabilises ride height and helps isolate road shock through the suspension. As a result, this complete air spring assembly suits BPW D30 trailer air suspension positions where a direct replacement restores load support and can help reduce uneven tyre wear.

Features

• Complete air spring assembly for BPW D30 trailer suspensions
• Rated for operating pressure up to 7 bar / 100psi
• Wide operating temperature range from -40°C to +70°C
• Designed to help maintain consistent ride height under varying payloads

Specifications and Materials

Part number: SP0020A.
This assembly uses a reinforced rubber bellows with metal end fittings typical of heavy trailer air springs, however specifications vary by OE build. Replacing the full assembly helps avoid reusing a fatigued bellows, so you can restore the suspension with a like-for-like unit.
Refer to the manufacturer part number guide for air springs to understand bellows versus assembly numbering and selection

Compliance and Safety
