Whiteline Billet Aluminum Pitch Stop Mount - 1993-2026 Subaru WRX, STI, Forester, Impreza

Eliminate Drivetrain Slop & Improve Throttle Response
Subaru designed the factory pitch stop mount to control engine and drivetrain movement, but the OEM plastic body and soft rubber bushings prioritize cabin quietness over performance. The Whiteline KBR39 Pitch Stop Mount is the solution for enthusiasts who want a more connected feel. By replacing the flexible factory unit with a rigid 6061-T6 Billet Aluminum arm, you dramatically reduce engine "pitch" during hard shifts, heavy acceleration, and aggressive braking.

Low-Compliance Bushing Technology
The KBR39 features Whiteline’s signature low-compliance synthetic elastomer bushings. These are engineered to eliminate the twisting and shudder found in factory mounts, allowing for faster, more responsive power delivery. Whether you’re piloting a classic GC Impreza or the latest 2026 WRX GT, this mount provides the positive feedback necessary for precision driving.

• Billet Construction: CNC machined from 6061-T6 aluminum for ultimate strength and weight savings.
• Anodized Protection: Finished in a protective coating to resist corrosion and look great under the hood.
• Enhanced Connectivity: Dramatically reduces engine movement for faster power delivery to the wheels.
• Rally-Proven Durability: Built to handle high-G loads and extreme performance environments.
