If you have raised the suspension on your van, you may well find the knock effect is the you require rear shock extensions and front ball joint spacers.
Here we have the rear shock extenders, which attach to the campers rear swing arm, and lift the syncro lower shock mount – which avoids the syncro rear shock topping out. Available from www.futbus.com.
Also, up front we have fitted syncro specific upper ball joint spacers, there several different suppliers out there, these ones also came from futbus.com, they are the same as available at gowesty.com
Both of these have been on the Westfalia for a few thousand miles now, and have been no problem at all. Don’t forget, if you have raised the suspension on your Syncro to get the alignment / geometry checked over!
