1 Trailing arms

General

Optimised trailing arm and air bag
attachment
O With further development of the Airlight II air suspension,
BPW introduced new optimised trailing arms from 1 July
2010 as well as a centrally bolted air bag BPW 30 / 30 K

SL for offset V = 20 mm.
A four-hole pattern was drilled into the new trailing arm
and the air bag was bolted directly onto the trailing arm
AL with a single bolt.
In addition to the new centrally bolted air bag, the familiar
air bags BPW 30 / 30 K and BPW 36 / 36 K / 36-1 can
continue to be attached using a steel plate and diff erent
off sets.
Note: Please note that the new air bag can only be
combined with the new trailing arm.
It is impossible to mount a new air bag onto an old trailing
arm by mistake due to the bolt / hole dia-meters.
From a technical point of view, there are no restrictions to
using both versions on the same axle or vehicle.
