Schumacher Cat L1 Evo layshaft lockout conversion
Schumacher’s new layshaft lockout conversion for the Cat L1 Evo reduces the rotating mass and the overall weight of the car. It incorporates a slipper lock out and is great for stock racing where maximum acceleration is required. The set includes a super lightweight titanium layshaft and fixing screw as well as 71T and 76T slipper lockout spur gears.
