KYB Suspension Strut and Coil Spring Assembly P/N:SR4018
KYB SR4596 front right strut assembly for the 2012-2015 Kia Optima carries vehicle weight, sets ride height and acts as the steering pivot. This complete strut and coil spring assembly also includes the mount.
A floaty ride, nose dive under braking or a clunk over bumps can mean a worn strut. These signs alone do not prove the strut is at fault; a worn sway bar link can make a similar clunk. This listing is one piece for the front right; the front left is separate, and both sides are normally replaced together. One goes on each side of the front axle.
This is a direct-fit replacement for the front right corner of the 2012-2015 Kia Optima.
Fit and size
Build and materials
One front right strut assembly with the strut, mount and coil spring.
Is this KYB front strut assembly the right one for the 2012-2015 Kia Optima?
Yes. KYB SR4596 is the front right strut assembly for the 2012-2015 Kia Optima. The front left side uses its own side-specific part.
Does this KYB loaded strut come with the mount and spring already attached?
Yes. This strut assembly is pre-assembled with a KYB Excel-G strut, the mount and the coil spring, so it arrives as one corner unit.
What is the coil spring on this KYB complete strut assembly made of?
On KYB SR4596 the coil spring is high carbon steel. It is developed around the vehicle's attributes and corner weights to help restore ride height within OE specifications.
Which signs can mean a front right strut assembly is wearing out?
A bouncy ride or a clunk over bumps can point to wear. With the engine off, you can also look for fluid leaking down the strut body.
Can KYB complete struts be used on a car with ESC and ABS?
Yes. This front right strut assembly is engineered to help vehicles with electronic safety systems such as ESC and ABS, and it has a side-specific design.
