GMC Sierra Transfer Case Brace - Wehrli - Bengal Blue - 08–10. Designed for 2008–2010 GMC Sierra models equipped with the Duramax LMM and Allison transmission, this single-stage, Bengal Blue powder-coated brace reinforces a known weak point in the driveline.

Developed and tested on high-power Duramax applications, the fabricated tubular steel support links the Allison rear housing to the transfer case to reduce driveline flex seen in off-road, pulling, and drag racing use. By distributing transfer-case load across the transmission center section, it helps prevent tail-housing flex that can lead to cracks, fluid leaks, and costly repairs. Installs with basic hand tools using existing OEM fasteners—no transmission or transfer case removal required.
