Knoxville Dragway 9.25.21 presented by
■ Silver Sport Transmissions , in conjunction with RAM Clutches , are proud to announce the title sponsorship of the September 25th Knoxville Tennessee event , ‘ The SST Shootout presented by RAM Clutches ’.
Silver Sport Transmissions ( Rockford , TN ) was founded by Jack Silver in 2014 . Silver had just purchased a 5-speed PerfectFit™ Kit for his 1986 Chevrolet El Camino “ Choo Choo ” when he heard about the previous owner ’ s ‘ issues ’. After investigating how a company with such great products ended up declaring bankruptcy , Silver found no fault in the staff or products . He gathered some investors and brought the popular products back to market and hired back all the old employees .
SST ’ s in-house engineering staff designs parts with an eye on quality , safety , and cost . SST ’ s technical service staff offer top notch customers guidance and product support . The sales staff have sold TREMEC and A41 PerfectFit and RestoFit ® kits for almost twenty years now . All of the staff at SST take pride in their work and are focused on how their work will impact the customer . TREMEC sales have increased allowing SST to go from a small TREMEC authorized reseller to one of the largest TREMEC Elite Distributors .
Silver Sport Transmissions has been a partner with RAM for several years and supplies RAM Clutches for their single and dual disc clutch systems and flywheels under the ‘ Advanced Friction ’ banner with their Tremec 5 and 6 speed transmission packages . SST will have a full display of their products and technical experts on hand to assist you with questions about your street and performance transmission needs .
RAM Clutches has been involved with SEGA since its founding by Quain Stott , and worked with Quain as well during all of his Pro Mod days of the 1980 ’ s into the 2000 ’ s . The majority of the racers in the SEGA are using RAM single disc sintered iron race clutches .
RAM was founded in 1973 by John Norcia in Canton , Ohio , and moved to Columbia SC in 1983 . It is now run by second generation sons Mike and Pat Norcia , who share a love for all manually shifted performance and racing vehicles . ‘ The Southeast Gassers have been big a shot in the arm to keeping stick shift drag racing alive and well , and along with the many other stick shift only groups around the country . We have been incredibly busy trying to keep up with the multitude of new cars being assembled for the SEGA , as well as keeping all the current customer units serviced ’, stated Mike Norcia .
