Trail-Gear Dual Case Adapter Couplers

Trail-Gear dual case adapter couplers are designed to work with OEM and Trail-Gear input gear splines. These high-strength splined couplers are made from heat-treated and carburized SCM415 alloy steel and used to upgrade your rear input from 21-spline to 23-spline, or to replace a worn coupler. These dual case adapter couplers are available in 21- or 23-spline (please count the input splines on your rear case input shaft) and may not work with other manufacturer's aftermarket gears. The 26-spline models are designed to fit 2.7 manual transmission style adapters only! Choose the dual case adapter couplers in the model designed for fitment on your application.
