Eagle Model RACING 2-Way Big Bore Shock Set 4WD LBL #2BS-4WD-LBL

This product is a high-precision 2-way big bore shock made from 60-61 hard aluminum processed with high-precision CNC. It is a shock absorber that allows for two types of use: an oil damper with a diaphragm and an aeration oil damper without a diaphragm. Various settings can be achieved with a combination of three types of springs with different hardness and three types of pistons with holes of 1.6, 1.7, and 1.8 mm. The diaphragm type is the most common, allowing for adjustment of damping force based on oil viscosity and piston hole size. It separates oil and air for more stable operation. The aeration type features a structure where oil and air mix, providing a progressive effect. When the piston moves, oil and air are compressed together, resulting in smooth damping force.
