Aluminum Third Members

For even greater weight savings, complement your Turn 9 lightweight housing with a complete ready to drop in 9-inch aluminum third member. Both the HD Pro and the Lightweight Aluminum gear cases are offered with choice of differential type, gear ratio and 1350 pinion yoke.

For severe or competitive application with hi-horsepower, we recommend the HD-Pro gear case with its 206-T4 heat treated case, thru bolt design and larger tail bearing. For more moderate applications and lightweight vehicles the Lightweight Aluminum gear case is a cost-effective solution.
