Chevrolet Silverado Transfer Case Brace by Wehrli, LB7/LLY/LBZ, Gloss White, 2001–2007. For Duramax/Allison trucks, it adds rigid support between the transmission and transfer case.

Tested for high-power use—off-roading, pulling, and drag racing—it reduces driveline flex and the risk of cracking the Allison tail housing. By spreading transfer case loads into the transmission center section, it limits vibration damage from failed u-joints or driveshafts. Tubular steel, gloss white single-stage powder coat. Installs with basic tools; no transmission or t-case removal; reuses OEM fasteners.
