#4.4BBL. Shift timing is certainly one of the most crucial aspects of getting any band or drum to hold up under extreme conditions. This PATC custom band lever is made in a 4.4 to 1 ratio to optimize shift timing when used in conjunction with larger oversized intermediate servos. The larger oversized band (direct drum) servos are excellent for improving apply pressure due to the larger surface area. The larger surface area is also important for the release as well, However with the 5:1 lever side loading and bind-up is not uncommon. This new band lever alleviates these issues. This new band lever is machined from high quality 4140 HTSR steel to ensure no side loading or deflection occurs. This band lever is ideal for diesel applications where no compromises are made. Fits 46RH, 46RE, 47RH, 47RE, 518, 618, 727.
