New standard silver
SMJ silver line springs are high-performance springs to satisfy all drivers, including top-class drivers.
New standard Short-type shock springs (20mm). We selected wire 1.4mm in diameter and accurately coiled and plated it. All the shock springs in different spring rates have the same specifications other than the number of turns in a coil so that it is easy to feel the difference between springs in different rates.
