The earliest red shocks were 8mm on the outside but were only a 6mm bore. TS/Ultima/Optima red shocks were 8mm bore and the Kyosho Golds and Platinums shocks were 10mm bore...like the RC10 shocks. Then you got the Big Pressure shocks from the Burns which were 12mm like many modern "big bore" shocks.
