Product Description

The BMR PSB001R Pinion Support Brace is a precision-engineered drivetrain upgrade designed for 2004-2007 Cadillac CTS-V models equipped with rear-wheel drive. On the first-generation CTS-V, the front differential bushing can allow excessive movement under high torque or aggressive acceleration, which may lead to drivetrain lash, unwanted vibration, and accelerated U-joint wear. The PSB001R addresses these issues by adding a robust polyurethane support at the front differential mount, dramatically reducing deflection and pinion rise for more consistent power delivery and improved throttle response.

This support brace is constructed from durable steel with a 95-durometer polyurethane bushing and finished in a corrosion-resistant red powdercoat. It installs quickly as a 100% bolt-on application with no welding or fabrication required, making it ideal for street performance vehicles and enthusiast builds that demand improved drivetrain stability. By limiting unwanted differential movement, the PSB001R helps maintain correct pinion angle and supports smoother, more predictable acceleration and braking response while preserving reliability and durability for spirited driving.
