Protect Your KCA313 Roll Center Kit with Replacement Boots
The Whiteline W0907 replacement dust boot kit provides new protective boots for the KCA313 Front Roll Center Adjustment Kit installed on 2002-2021 Subaru WRX and related models. Over time, the dust boots on the KCA313 can tear or degrade — leaving the ball joint mechanisms exposed to contamination. Replacing the boots before complete failure extends the service life of the underlying kit.

Why Dust Boots Matter
The dust boots on the KCA313’s ball joint elements seal out road contamination — water, dirt, and grit that would otherwise accelerate wear of the joint surfaces. A torn or missing boot means the joint is unprotected. Replacing the boots promptly when damage is noticed prevents a simple boot replacement from becoming a complete kit replacement.

Service Life Extension
The KCA313 roll center kit is a quality investment. The W0907 boot kit is the maintenance hardware that protects that investment. Inspecting the boots at each service interval and replacing them when signs of cracking or tearing appear is the correct long-term ownership approach.

Compatible Models
The W0907 is correct for any Subaru model with the KCA313 installed. This covers the full range of WRX, STI, Forester, and Impreza platforms that use the KCA313 roll center kit.
