Boge Automatics Struts
If you're looking for economical replacement shocks and liked how the car rode when new, these are the original shocks as supplied to Volvo at the factory. Not recommended for lowered cars.
Boge Turbo Gas Struts
For a moderately priced upgrade with a slightly more controlled feel than stock, consider the gas-charged Boge Turbo Gas. These offer a lifetime warranty and are acceptable for use on stock height or lowered cars.
