Shootout

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 .

■ The toughest GM 4L80-E input shaft ever made for 1,000 + horsepower vehicles is now available from Sonnax . It ’ s an extreme duty shaft designed for extreme applications , when drivers want to go all out on the street or strip without worrying about transmission failure .

The input shaft in the 4L80-E and 4L85-E is a major weak point in these otherwise very capable units where both OE and aftermarket shafts commonly fail under added power .

The company ’ s new , extreme duty input shaft is made from an exceptionally tough , highstrength Aermet steel alloy that undergoes custom heat treatment for added durability .
