Transmission & Transfer Case Upgrades

Everything the engine makes has to go through the transmission and transfer case before it reaches the axles, which makes these components the bottleneck in any serious power or capability build. Transmission & Transfer Case Upgrades address that weak point with hardware designed to handle the added torque, heat, and stress that come with larger tires, lifted suspensions, and higher output engines.

 

Automatic transmission builds typically start with a shift kit or valve body upgrade before moving into billet input shafts and drum assemblies built to handle higher torque loads. Transfer case upgrades cover everything from skid plates and armor to full replacement cases with better gear reduction ratios for dedicated trail rigs.

 

Transmission & Transfer Case Upgrades are one part of a driveline conversation that extends through the rest of the drivetrain. The full range of off-road drivetrain components is at Off-Road 4x4 Drivetrain Parts, top-selling parts across all categories are at Most Popular, and gear ratio changes that work alongside transfer case upgrades are at Ring & Pinion Gears.
