King Shocks Pure Race Series 3.5 X 18 4 Tube Bypass Piggyback Reservoir Shock - RS3518-BP4P

The magic all happens with the piston which creates the King ride quality that sets us apart. Each bypass stage is separately tunable and operates independently from the others. King Pure Race series bypass shocks offer the ultimate in performance and adjustability. After plating we take the time to precision bore and hone our shock tubes to size within +/- .001 to insure cylindricity and a tight piston seal which maximizes flow characteristics and valving function. Every aspect of their design has been optimized for all out racing. King uses high strength heat treated adjusting screws that don't bend or break like low quality set screws do. The bypass tube design maximizes flow while maintaining a compact low profile envelope. With the position sensitive design, compression tubes have no influence on rebound tubes and vice versa. The bypass ports in the shock tubes are cnc drilled then hand deburred and polished before the bypass tubes are aircraft quality tig welded by our certified welders.The finished assemblies are then pressure tested to 300 psi and sent out for plating. King offer the only shock in the world with this feature. Kings extensive knowledge of fluid dynamics has been put to use in the port designs on our cold drawn 2024 billet aluminum piston. The o-ring seals are made from Viton material to endure sustained high temperatures and the wiper seal is a carbon composite m Pure race series;3.5 diameter body;18 travel;4 tube bypass design;Compressed length: 30.06;Extended length: 48.06;Replaceable Teflon lined stainless steel spherical bearings eyelet mounts;California Residents: WARNING Due to the tight tolerances we maintain our valves have a high level of precise adjustability, 14 turns to be exact. King bypass valves and springs are made from the same heat treated stainless steel alloy as our valve shims to provide consistent fade free operation with no unregulated bypass flow. Each bypass shock is custom made for your application so you have many options available when determining the quantity and location of the bypass tubes. The piston glides on a Teflon bronze wear band made from the same material used on the beds and ways of precision CNC machines.
