Review on ACDelco Professional 45H2124 Rear Coil Spring Set - Reliable Suspension Upgrade for Enhanced Performance by Orlando Mohr

I think it may have one more spring than the OEM but the overall width and length is the same as far as I can remember. My car rides a little higher than the 110,000 mile springs I replaced. If you accidentally hear a tambourine sound coming from your car when hitting a bump, it's the sound of a broken spring. They replaced my broken spring and are working perfectly. Also, according to the box I received, they are made in the USA.
