Looking for a good suspension shop, suggestions?

[Rob]

Hello

I'm looking for a shop that can do an air-suspension upgrade on a 5 ton truck that has been converted to an expedition camper. The goal is to replace the overload springs with an air suspension to dampen the harshness of the ride a bit while retaining the standard leaf springs as the structural components (i.e. not converting to a complete air-ride system). Anyone know of a shop with a good reputation and some engineering skills that could help make this upgrade? Any suggestions for shops in the lower mainland / Fraser Valley would be appreciated.

Cheers, Rob
