Shifter Knob Adapter 3/8-16

The Shifter Knob Adapter 3/8-16 by LOKAR is a precision-engineered threading adapter designed for custom shift knob installations on manual and automatic transmissions. This adapter serves as the critical mechanical bridge between your factory or custom shift rod and an aftermarket shifter knob, allowing you to upgrade the factory unit with high-end custom replacements.

Manufactured to exacting standards by LOKAR, the Shifter Knob Adapter 3/8-16 features a 3/8-16 thread pitch specification that matches industry-standard shift rod diameters found on countless production and custom vehicles. Its compact profile—measuring 5.8 inches in overall length with a 0.9-inch diameter body—ensures clean fitment within tight engine compartments and transmission tunnel spaces without interfering with surrounding components.

Whether you're restoring a classic muscle car, building a hot rod, or modernizing your daily driver, this adapter ensures a secure, vibration-free connection that maintains the integrity of your shift linkage while accommodating quality aftermarket knob designs. Its lightweight construction at just 0.31 pounds adds negligible weight while maintaining the rigidity required to transmit precise shift inputs without play or flex, critical for smooth gear selection and positive engagement.
