High carbon steel coil spring: developed considering vehicle attributes and corner weights to help keep ride height within OE specifications without sacrificing ride quality.
Safety-system aware: engineered to help vehicles with electronic safety systems (ESC, ABS, etc.).
A strut assembly handles vehicle weight, sets ride height, and acts as the steering pivot. Sold individually as a front unit; replacing the left and right on the same axle together is recommended for even, balanced handling.
