The Japanese RC brand Team Axon announced the new Revoshock dampers. These big bore shock absorbers are designed for the Yokomo YD-2 and YD-4 drift cars and utilise 11.5mm diameter 16-hole shock pistons (with HVF-coated threaded alloy shock bodies for ultra low friction). The clearance between the piston and shock body is only 0.025mm, ensuring minimal oil blow-by and thus predictable shock performance.
The Revoshock uses a new piston shaft seal design with the lower cartridge seals with a smaller diameter compared to standard P3 O-rings, which ensures the seals are not being pinched by the shock body which created a floating design that leads to virtually no friction between the seals and the shock shaft.
