Our standard editions, called Blueline and Blackline, have been an integral part of the Wilbers Adjustline group for years. It is important to know that the two colour options actually only differ in appearance and not technically. While the Wilbers Blueline is delivered with blue springs, red rebound and spring preload adjustment units and red/blue compression adjusters, the Blackline has black springs and silver adjustment units. Both editions have in common that they are individually manufactured according to customer specifications, have a 5 year factory warranty and an ABE**. Alternative RAL colours of the springs for further individualisation of your desired spring struts are available at extra charge!
Of course, the colours of the adjustments can be chosen free of charge from grey, red or blue!
