Chevrolet Silverado HD Transfer Case Brace - Wehrli - Sparkle Granny Smith - 2011–2019. Purpose-built support that ties the Allison transmission to the transfer case to add strength and help control driveline flex on LML and L5P trucks.

Developed and tested for high horsepower Duramax applications, this fabricated tubular steel brace reinforces the weaker tail housing and helps distribute transfer case loads into the transmission center section. By reducing flex that can contribute to cracked housings, fluid leaks, and costly driveline damage during off-road, pulling, or drag use, it offers durable support without complicating service. Finished in single stage Sparkle Granny Smith powder coat. Installs with basic hand tools, reuses OEM fasteners, and requires no transmission or transfer case removal.
