Chevrolet Silverado Transfer Case Brace – Wehrli – Illusion Blueberry – 2011–2019. A bolt-on brace for LML/L5P Duramax trucks with the Allison transmission that adds strength and reduces driveline flex.

Developed and tested for demanding use—off-roading, pulling, and drag racing—this fabricated tubular-steel support ties the Allison rear housing to the transfer case, spreading load across the transmission center section. Reinforcing the tail-housing area helps prevent cracks, fluid leaks, and costly damage from vibration caused by issues like a bad u-joint or driveshaft. Finished in Illusion Blueberry single-stage powder coat and built to install with basic hand tools.
