The Correct Hardware to Complete Your Whiteline Lateral Link Install
If you’re running Whiteline KTA108, KTA109, or KTA123 rear lateral links on your 2002-2007 Subaru WRX or STI, this is the matching service kit with the correct hardware to complete the installation. These lateral link kits use specific bushings and hardware that aren’t interchangeable with other service parts — this kit ensures you have everything you need to install the arms correctly and service them in the future.

DETAILS

• Service kit for Whiteline lateral link kits KTA108, KTA109, and KTA123
• Contains correct bushings and hardware for proper installation
• Required for complete and correct assembly of these lateral link kits
• Fitment: 2002-2007 Subaru WRX and STI

Why the Correct Service Kit Matters
Whiteline’s adjustable rear lateral link kits use proprietary bushing geometry and hardware spec to achieve their alignment correction function. Using incorrect or generic hardware during installation or service can compromise the adjustment function and reduce durability. This kit contains the correct components.

Keeping Lateral Links Serviceable
Whiteline designs their lateral link kits for long-term serviceability — the hardware can be replaced without having to buy an entirely new arm kit. Stocking this service kit before you need it means a quick fix when the time comes rather than an extended wait for parts.

Complete Your GD Subaru Rear Suspension Build
The KTA108, KTA109, and KTA123 lateral links are key components in any GD WRX or STI rear suspension build. Getting the installation correct the first time — with the correct hardware from this service kit — protects the investment in the links themselves.

Why Choose Whiteline

Whiteline has been engineering suspension components from their facility in Australia since 1979. Every product in their catalog is developed with a clear goal: measurable improvement in handling, stability, and tyre contact. Whiteline’s polyurethane bushings, sway bars, control arms, and alignment correction kits are engineered using finite element analysis and validated on track before they reach the market. Their components are direct-fit, bolt-on solutions designed for enthusiasts who want real performance gains without fabrication or custom work.
