Many modern and European-style shift knobs use a metric M16 x 1.5 thread, which will not install on the smaller SAE-threaded shifter sticks found in most domestic and aftermarket shifters. This adapter kit bridges that gap, letting you run an M16 x 1.5 knob on a stick with a common imperial thread instead of replacing the stick or re-tapping the knob.

Hurst 16900HST Features:

• Adapts M16 x 1.5 threaded shift knobs to most smaller imperial threaded shifter sticks
• Includes eight threaded inserts: 1/4 in.-20, 5/16 in.-18, 5/16 in.-24, 3/8 in.-16, 3/8 in.-24, 7/16 in.-14, 1/2 in.-13 and 1/2 in.-20
• Matching stainless steel jam nuts lock the knob in the desired orientation
• Aluminum, steel and stainless steel construction
• Check your stick thread size before installation to select the correct insert
