The Heavy Hitter ETM RTR Billet Shift Lock with Delrin Slider is a CNC-machined billet aluminum shift lock bracket for the ETM RTR and RTR Lite, built as a lighter and stronger alternative to the flat-cut steel shift locks used by competitors. Inner and outer gussets add rigidity and impact resistance without adding weight. The fully machined Delrin slider peg provides a low-friction surface for smooth slides and is designed as a controlled break point in a crash protecting the frame and bracket from damage.
