Replacing struts used to require specialized tools to compress, remove, and transfer the old spring and mount. Our Pre-assembled, complete strut & spring assemblies come with all new parts and make the job much quicker and easier for the do-it-yourself mechanic.

Upper Strut Mount
Strut Bearing

Install Tip: To keep your vehicle operating safely and as designed:
Replace your shocks & struts in pairs. This will avoid mixing parts (old and new or brands). Mixing parts can cause variations in movement between the vehicle’s body and wheel, resulting in handling irregularities.
Have an alignment performed after replacing your shocks and struts. This will ensure proper tracking and protect your vehicle’s tires from premature wear.

The struts seem reasonably priced and it was easy to place the order. I received the stuts within a few days of ordering. One of the screw holes for attaching one of the brackets near the base (I think the right hand side) didn't exactly line up. Fairly simple fix by flatting out the bracket to get the screw to line up. Other than that it was pretty easy to install.

How do I know if my Buick has magnetic ride?
Thank you for your inquiry! Electrical connectors/wiring at the struts or shocks. Magnetic Ride Control shocks and struts have electrical connectors attached to them. If there are no wires going to the struts or shocks, the vehicle likely does not have Magnetic Ride Control
