Convert a smooth, non-threaded shift lever into a secure attachment point for aftermarket selector knobs with this precision-machined aluminium adapter. Built from hardened aluminium alloy, the unit features an outer threading of either M10x1.5 or M12x1.25, allowing direct bolt-on compatibility across widely used manual transmission setups. The M12x1.25 variant seats perfectly into BMW and Mini selector levers, while the M10x1.5 version aligns with most Honda manual gearboxes. A 13mm inner bore accepts male splitter or splined shaft ends, eliminating lever play and restoring crisp shifting action. Available in six distinct finishes, this upgrade replaces cracked factory bases without requiring welding or custom fabrication.

Benefits & Tips

  • Measure your existing shifter rod and match the outer thread specification before ordering to guarantee a straight-fit exchange.
  • Clean oil residue from the inner shaft using electrical contact cleaner so the included plastic sleeves seat tightly and prevent rotation.
  • Thread each set screw into the designated holes and snug them down incrementally to maintain consistent feedback during aggressive cornering shifts.
