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.
Specially selected inner diameters of the upper S and lower SS-sized O-rings ensure the shocks are still as leak-free as possible while the HVF-coated piston shaft further reduce overall friction. The result is a shock absorber that is able to generate more traction due to being as smooth as possible.
Included in the set come the shock bodies, upper and lower caps, spring pre-load collar as well as the piston rods and pistons. The plastic parts, pivot balls and shock springs are not included as these are parts that can be taken from the standard Yokomo shocks.
