Construction & Design

The bushings are crafted from premium polyurethane, a material chosen for its excellent durability and resistance to harsh environmental conditions. Unlike rubber, polyurethane maintains its shape and performance over a wide temperature range, ensuring consistent handling and response. The kit's components are precisely molded to match OEM specifications, allowing for a direct bolt-in replacement without the need for modifications.

Prothane's design emphasizes longevity and performance, with bushings that resist cracking, tearing, and compression set. The kit includes all necessary hardware and mounting components, making installation straightforward for experienced DIY enthusiasts or professional mechanics. The result is a suspension system that feels tighter, more responsive, and more predictable.

The Prothane Suspension Bushing Kit is designed as a direct bolt-on upgrade for your Subaru Impreza or WRX from 1998 to 2005. No cutting, drilling, or complex modifications are required. The installation process involves removing the existing rubber bushings and pressing in the new polyurethane components using standard tools. Basic suspension knowledge is recommended, but the process is straightforward for those familiar with suspension work.

• Includes all necessary bushings for sway bars, control arms, trailing arms, and shifter linkage.
• Installation typically takes a few hours depending on your experience and tools available.
• Ensure proper lubrication during installation to facilitate pressing in the bushings and to prevent squeaks.
