V-Drive Clutch Logs 4000 Laps And Still Going Strong
Karl Fredrickson, editor of Speedway Illustrated & accomplished racer, has been running a Quarter Master® 5.5” V-Drive clutch in his 600-horsepower, 2600-pound modified car with 15"-wide tires. For over 4000 laps, it has performed flawlessly without a single slip. At 2000 laps, he opened the clutch up for inspection, but everything looked fine so he put it back together and ran another 2000 laps. Now, at over 4000 laps, the plates are still .100" thick.
Fredrickson attributes his success with the V-Drive clutch to its ultra-high quality parts, following instructions, using a winch to load and unload the car, and pulling the car out of gear to coast through the pits instead of slipping the clutch.
Karl’s clutch has been essentially service free, but when rebuild time does arrive, Quarter Master® has the perfect solution. Quarter Master® offers Clutch Service Packs so a do-it-yourself racer like Karl can replace just the parts that wear, in his own shop, without the expense of having to replace the whole clutch or the wasted time of shipping it back to the manufacturer. Quarter Master® Service Packs for 5.5" Clutches maximize the integrity of your clutch unit to avoid failure and enhance performance.
During clutch inspection, racers and builders examine the friction discs but often overlook the pressure plate and floater plates contained within the clutch housing. These parts may not suffer as high a wear rate as the friction disc does, but they are still susceptible to some wear. Without full attention to every component within the clutch, a competitor may be sidelined prematurely. Don’t let this happen to you. Use the Quarter Master® Service Packs for 5.5" Clutches to change the used internal clutch components.
The new components in these clutch packs increase both holding and torque capacity while improving pedal feel and drivability. Quarter Master® Service Packs include all the appropriate disc packs, utilizing the latest in friction material, floaters, pressure plates, flange nuts and washers for each unique application. These complete kits ensure a racer’s competitiveness on the track by providing an simple and affordable option to replacing a complete clutch unit.
While Karl has had his success with a Quarter Master® 5.5” V-Drive clutch, Service Packs are available for all Quarter Master® 5.5" Pro Series, V-Drive and Optimum V-Drive 2 or 3 Disc Clutches. Learn more at
