About us

QUARTER MASTER provides winning clutches & driveline components to racers from Super Speedway to the Bullring...from IRL to Rally... from NASCAR to the "Weekend Warrior"!

QUARTER MASTER began operations in 1972,
and since that date, QUARTER MASTER
products have enjoyed a long history of
track-proven race-winning results. That
long-standing enjoyment has come from a
“race-team like effort” with attention to detail,
and from listening and responding to the racer.
Our products are built to exceed the racer’s
demand and need for reliability, high-performance
& durability. Our passion & our commitment is to
the racer’s goal…winning!
