Quarter Master

<h3>Quarter Master: Race-Proven Driveline Performance Since 1958</h3><p><strong>Quarter Master®</strong> was founded in 1958 by Ed Stoffels, a racer and machinist who started the company as a quarter-mile drag race chassis builder — giving the brand its now-iconic name. In the early 1970s, Stoffels recognized a gap in the U.S. market for multi-plate racing clutches, which were widely used in Europe but nearly impossible to source domestically. He seized the opportunity and began manufacturing them himself, setting Quarter Master on a course to become the dominant force in racing clutch design.</p><p>By 1976, Quarter Master had evolved into a full-scale manufacturing and service operation, recognized industry-wide as the leader in clutch and clutch component production. The company continued to expand its scope, adding quick-change gears for midget and stock cars, flywheels, driveshafts, bellhousings, and starters to its lineup. Today, Quarter Master serves racing disciplines ranging from asphalt short track and dirt oval to road racing, open wheel, driving schools, and the NASCAR Cup Series.</p><p>At the heart of the Quarter Master catalog are its legendary <a href="/1325-quarter-master-clutch-kit-1993">clutch kits</a>, which span a complete range of applications and performance levels. Whether a racer needs a compact 5.5&quot; unit for a lightweight open-wheel machine or a heavy-duty 7.25&quot; multi-disc setup for a high-torque stock car engine, Quarter Master engineers every clutch with premium friction material for maximum torque capacity while minimizing rotational mass. Flagship lines like the Optimum-V, Optimum-RR, and Pro Series have earned podium finishes at the highest levels of motorsport.</p><p>Supporting those clutch systems is an equally comprehensive range of <a href="/1325-quarter-master-clutch-components-201267">clutch components and service parts</a>. From friction disc packs and pressure plates to floater plates, hydraulic release bearings, and flywheel bolt kits, Quarter Master ensures that every internal component can be individually inspected, serviced, and replaced — extending the life of the clutch housing and keeping racers competitive lap after lap.</p><p>Proper installation starts with precision, which is why Quarter Master's <a href="/1325-quarter-master-clutch-alignment-tool-7700">clutch alignment tools</a> are built to tighter tolerances than typical plastic alternatives, delivering more consistent disc centering. And for teams running quick-change rear ends, Quarter Master rounds out its driveline offerings with <a href="/1325-quarter-master-differential-bearing-kit-14612">differential bearing kits</a> and related rear axle components designed to work in harmony with the brand's full driveline ecosystem.</p><p>Every Quarter Master product is manufactured on state-of-the-art CNC turning centers, mills, gear-cutting, and broaching equipment, and subjected to rigorous quality control before leaving the facility. For racers who demand nothing less than the best from their driveline, Quarter Master delivers the engineering, the heritage, and the race-winning results to back it up.</p>
