BOSCH Rev-limiting rotors.
These little things can save your motor, if you miss a shift or want to limit
the max RPM your motor will see.
The 5,400rpm unit is good for Bus (you cant hear the engine way in the back!)
Also good for sand rail's, you can't lift off the gas as fast as the rpms can climb!
