FAQ - Answer 1Yes. Although shocks and struts perform a similar function, they vary greatly in their design. The major difference between shocks and struts is that a strut is a structural part of the vehicles suspension system where a shock is not. A strut is also a crucial part of the vehicles steering system and greatly affects alignment angles.
FAQ - Answer 2Yes. You should have your vehicle aligned if you are replacing your vehicle's struts. However, it is not necessary to get your vehicle aligned when replacing your vehicle's shocks unless there was a previous issue.
FAQ - Answer 3Yes. It is important to choose the correct shock or strut for your vehicle model and year, as well as for the location in the vehicle.
