GMC Duramax Transfer Case Brace - Wehrli - Flat Black - 2011–2019. Purpose-built for LML/L5P trucks with Allison, this brace adds strength where the drivetrain needs it most.

Developed and tested on high-power Duramax builds, it ties the Allison’s rear housing to the transfer case to spread load into the stronger center section. This helps cut driveline flex in off-roading, pulling, and drag racing, and helps guard against cracked tail housings, leaks, and repairs from vibration. Durable flat black single-stage powder coat. Installs with basic tools, reuses OEM fasteners; no transmission or transfer case removal.
