REVOSHOCK II for Yokomo YD-2/YD-4

DD-YS-002

AXON's newest high-performance shocks for drift cars have obtained amazing cornering performance with Big Bore Cylinders & Big Bore Pistons. The ultimate oil damper for drift cars that has significantly improved performance from the REVO SHOCK.

The piston operation is surprisingly smooth and does not hinder the movement of the suspension. The airtightness of the oil is improved and it is possible to maintain the damper performance for a long time. Also, in order to match the suspension behavior of the front and rear of the car, the specifications of the piston were changed and optimization was performed.

The ultimate piston clearance that creates amazing traction with the newly designed 12-hole & 16-hole piston.

The outer diameter of the piston, which greatly affects the maximization of damper capacity, which is important for producing high traction, is 11.5 mm, which is the size of a high big bore. And the clearance between the piston and the cylinder is only 0.035mm in order to minimize the piston runout when the piston strokes. In addition, the front and rear pistons have different specifications, and we have developed a newly designed 12-hole and 16-hole piston, which has succeeded in significantly improving performance. The inner surface of the cylinder is mirror-processed and then finished with Axon's original "HVF coating", which is formed of a strong fluorine film, achieving ultra-low friction.

Evolved and reborn the NEW O-ring floating seal structure

It is important that the suspension of the drift car has as low friction as possible. In REVOSHOCK II, the double floating O-ring used in the standard oil damper of Yokomo BD10 has been further softened, and low friction and airtightness * 1 have been greatly improved. Furthermore, the size of the O-ring chamber has been reviewed, and the precision rod guide that has been optimized by tapering the contact surface with the O-ring has been standardized to create an ideal oil seal structure.

* Airtightness does not mean that there is a minimum amount of oil bleeding required for sliding lubrication of the piston rod, and no oil leaks at all.

New "Precision Shock Bladder V2" that expands the traction range

REVOSHOCK II has developed and adopted a new diaphragm to obtain the best damper damping. Compared to the Precision Shock Bladder, the new "Precision Shock Bladder V2" has been newly designed to improve airtightness and prevent the internal pressure of the damper from changing extremely significantly. Therefore, the damper damping works widely and flexibly against changes in the behavior of the machine, preventing sudden tire grip loss and maintaining traction.

HVF coating specifications that also boast the best lubrication performance of the piston rod.

The piston rod for REVOSHOCK II has a standard dimension setting of 0.001 mm and is mirror-finished, and then finished with Axon's original "HVF coating", which is formed of a strong fluorine film like a cylinder, to produce the best damping performance.
